1 Peter

1Chapter

Greeting

1Peter, an apostle of Jesus Christ: To those chosen, living as exiles dispersed abroad in Pontus, Galatia, Cappadocia, Asia, and Bithynia, chosen 2according to the foreknowledge of God the Father, through the sanctifying work of the Spirit, to be obedient and to be sprinkled with the blood of Jesus Christ. May grace and peace be multiplied to you.

A Living Hope

3Blessed be the God and Father of our Lord Jesus Christ. Because of his great mercy he has given us new birth into a living hope through the resurrection of Jesus Christ from the dead 4and into an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you. 5You are being guarded by God’s power through faith for a salvation that is ready to be revealed in the last time. 6You rejoice in this, even though now for a short time, if necessary, you suffer grief in various trials 7so that the proven character of your faith —more valuable than gold which, though perishable, is refined by fire —may result in praise, glory, and honor at the revelation of Jesus Christ. 8Though you have not seen him, you love him; though not seeing him now, you believe in him, and you rejoice with inexpressible and glorious joy, 9because you are receiving the goal of your faith, the salvation of your souls.
10Concerning this salvation, the prophets, who prophesied about the grace that would come to you, searched and carefully investigated. 11They inquired into what time or what circumstances the Spirit of Christ within them was indicating when he testified in advance to the sufferings of Christ and the glories that would follow. 12It was revealed to them that they were not serving themselves but you. These things have now been announced to you through those who preached the gospel to you by the Holy Spirit sent from heaven —angels long to catch a glimpse of these things.

A Call to Holy Living

13Therefore, with your minds ready for action, be sober-minded and set your hope completely on the grace to be brought to you at the revelation of Jesus Christ. 14As obedient children, do not be conformed to the desires of your former ignorance. 15But as the one who called you is holy, you also are to be holy in all your conduct; 16for it is written, Be holy, because I am holy. 17If you appeal to the Father who judges impartially according to each one’s work, you are to conduct yourselves in reverence during your time living as strangers. 18For you know that you were redeemed from your empty way of life inherited from your ancestors, not with perishable things like silver or gold, 19but with the precious blood of Christ, like that of an unblemished and spotless lamb. 20He was foreknown before the foundation of the world but was revealed in these last times for you. 21Through him you believe in God, who raised him from the dead and gave him glory, so that your faith and hope are in God.
22Since you have purified yourselves by your obedience to the truth, so that you show sincere brotherly love for each other, from a pure heart love one another constantly, 23because you have been born again —not of perishable seed but of imperishable—through the living and enduring word of God. 24For All flesh is like grass, and all its glory like a flower of the grass. The grass withers, and the flower falls, 25but the word of the Lord endures forever. And this word is the gospel that was proclaimed to you.
2Chapter

The Living Stone and a Holy People

1Therefore, rid yourselves of all malice, all deceit, hypocrisy, envy, and all slander. 2Like newborn infants, desire the pure milk of the word, so that by it you may grow up into your salvation, 3if you have tasted that the Lord is good. 4As you come to him, a living stone—rejected by people but chosen and honored by God— 5you yourselves, as living stones, a spiritual house, are being built to be a holy priesthood to offer spiritual sacrifices acceptable to God through Jesus Christ. 6For it stands in Scripture: See, I lay a stone in Zion, a chosen and honored cornerstone, and the one who believes in him will never be put to shame.
7So honor will come to you who believe; but for the unbelieving, The stone that the builders rejected— this one has become the cornerstone,
8and A stone to stumble over, and a rock to trip over. They stumble because they disobey the word; they were destined for this.
9But you are a chosen race, a royal priesthood, a holy nation, a people for his possession, so that you may proclaim the praises of the one who called you out of darkness into his marvelous light. 10Once you were not a people, but now you are God’s people; you had not received mercy, but now you have received mercy.

A Call to Good Works

11Dear friends, I urge you as strangers and exiles to abstain from sinful desires that wage war against the soul. 12Conduct yourselves honorably among the Gentiles, so that when they slander you as evildoers, they will observe your good works and will glorify God on the day he visits.
13Submit to every human authority because of the Lord, whether to the emperor as the supreme authority 14or to governors as those sent out by him to punish those who do what is evil and to praise those who do what is good. 15For it is God’s will that you silence the ignorance of foolish people by doing good. 16Submit as free people, not using your freedom as a cover-up for evil, but as God’s slaves. 17Honor everyone. Love the brothers and sisters. Fear God. Honor the emperor.

Submission of Slaves to Masters

18Household slaves, submit to your masters with all reverence not only to the good and gentle ones but also to the cruel. 19For it brings favor if, because of a consciousness of God, someone endures grief from suffering unjustly. 20For what credit is there if when you do wrong and are beaten, you endure it? But when you do what is good and suffer, if you endure it, this brings favor with God.
21For you were called to this, because Christ also suffered for you, leaving you an example, that you should follow in his steps. 22He did not commit sin, and no deceit was found in his mouth; 23when he was insulted, he did not insult in return; when he suffered, he did not threaten but entrusted himself to the one who judges justly. 24He himself bore our sins in his body on the tree; so that, having died to sins, we might live for righteousness. By his wounds you have been healed. 25For you were like sheep going astray, but you have now returned to the Shepherd and Overseer of your souls.
3Chapter

Wives and Husbands

1In the same way, wives, submit yourselves to your own husbands so that, even if some disobey the word, they may be won over without a word by the way their wives live 2when they observe your pure, reverent lives. 3Don’t let your beauty consist of outward things like elaborate hairstyles and wearing gold jewelry or fine clothes, 4but rather what is inside the heart —the imperishable quality of a gentle and quiet spirit, which is of great worth in God’s sight. 5For in the past, the holy women who put their hope in God also adorned themselves in this way, submitting to their own husbands, 6just as Sarah obeyed Abraham, calling him lord. You have become her children when you do what is good and do not fear any intimidation.
7Husbands, in the same way, live with your wives in an understanding way, as with a weaker partner, showing them honor as coheirs of the grace of life, so that your prayers will not be hindered.

Do No Evil

8Finally, all of you be like-minded and sympathetic, love one another, and be compassionate and humble, 9not paying back evil for evil or insult for insult but, on the contrary, giving a blessing, since you were called for this, so that you may inherit a blessing.
10For the one who wants to love life and to see good days, let him keep his tongue from evil and his lips from speaking deceit, 11and let him turn away from evil and do what is good. Let him seek peace and pursue it, 12because the eyes of the Lord are on the righteous and his ears are open to their prayer. But the face of the Lord is against those who do what is evil.

Undeserved Suffering

13Who then will harm you if you are devoted to what is good? 14But even if you should suffer for righteousness, you are blessed. Do not fear them or be intimidated, 15but in your hearts regard Christ the Lord as holy, ready at any time to give a defense to anyone who asks you for a reason for the hope that is in you. 16Yet do this with gentleness and reverence, keeping a clear conscience, so that when you are accused, those who disparage your good conduct in Christ will be put to shame. 17For it is better to suffer for doing good, if that should be God’s will, than for doing evil.
18For Christ also suffered for sins once for all, the righteous for the unrighteous, that he might bring you to God. He was put to death in the flesh but made alive by the Spirit, 19in which he also went and made proclamation to the spirits in prison 20who in the past were disobedient, when God patiently waited in the days of Noah while the ark was being prepared. In it a few—that is, eight people —were saved through water. 21Baptism, which corresponds to this, now saves you (not as the removal of dirt from the body, but the pledge of a good conscience toward God) through the resurrection of Jesus Christ, 22who has gone into heaven and is at the right hand of God with angels, authorities, and powers subject to him.
4Chapter

Following Christ

1Therefore, since Christ suffered in the flesh, arm yourselves also with the same understanding —because the one who suffers in the flesh is finished with sin — 2in order to live the remaining time in the flesh no longer for human desires, but for God’s will. 3For there has already been enough time spent in doing what the Gentiles choose to do: carrying on in unrestrained behavior, evil desires, drunkenness, orgies, carousing, and lawless idolatry. 4They are surprised that you don’t join them in the same flood of wild living—and they slander you. 5They will give an account to the one who stands ready to judge the living and the dead. 6For this reason the gospel was also preached to those who are now dead, so that, although they might be judged in the flesh according to human standards, they might live in the spirit according to God’s standards.

End-Time Ethics

7The end of all things is near; therefore, be alert and sober-minded for prayer. 8Above all, maintain constant love for one another, since love covers a multitude of sins. 9Be hospitable to one another without complaining. 10Just as each one has received a gift, use it to serve others, as good stewards of the varied grace of God. 11If anyone speaks, let it be as one who speaks God’s words; if anyone serves, let it be from the strength God provides, so that God may be glorified through Jesus Christ in everything. To him be the glory and the power forever and ever. Amen.

Christian Suffering

12Dear friends, don’t be surprised when the fiery ordeal comes among you to test you, as if something unusual were happening to you. 13Instead, rejoice as you share in the sufferings of Christ, so that you may also rejoice with great joy when his glory is revealed. 14If you are ridiculed for the name of Christ, you are blessed, because the Spirit of glory and of God rests on you. 15Let none of you suffer as a murderer, a thief, an evildoer, or a meddler. 16But if anyone suffers as a Christian, let him not be ashamed but let him glorify God in having that name. 17For the time has come for judgment to begin with God’s household, and if it begins with us, what will the outcome be for those who disobey the gospel of God?
18And if a righteous person is saved with difficulty, what will become of the ungodly and the sinner?
19So then, let those who suffer according to God’s will entrust themselves to a faithful Creator while doing what is good.
5Chapter

About the Elders

1I exhort the elders among you as a fellow elder and witness to the sufferings of Christ, as well as one who shares in the glory about to be revealed: 2Shepherd God’s flock among you, not overseeing out of compulsion but willingly, as God would have you; not out of greed for money but eagerly; 3not lording it over those entrusted to you, but being examples to the flock. 4And when the chief Shepherd appears, you will receive the unfading crown of glory. 5In the same way, you who are younger, be subject to the elders. All of you clothe yourselves with humility toward one another, because God resists the proud but gives grace to the humble.

Conclusion

6Humble yourselves, therefore, under the mighty hand of God, so that he may exalt you at the proper time, 7casting all your cares on him, because he cares about you. 8Be sober-minded, be alert. Your adversary the devil is prowling around like a roaring lion, looking for anyone he can devour. 9Resist him, firm in the faith, knowing that the same kind of sufferings are being experienced by your fellow believers throughout the world.
10The God of all grace, who called you to his eternal glory in Christ, will himself restore, establish, strengthen, and support you after you have suffered a little while. 11To him be dominion forever. Amen.
12Through Silvanus, a faithful brother (as I consider him), I have written to you briefly in order to encourage you and to testify that this is the true grace of God. Stand firm in it! 13She who is in Babylon, chosen together with you, sends you greetings, as does Mark, my son. 14Greet one another with a kiss of love. Peace to all of you who are in Christ.

Chapter 3
CSB

What Is Apologetics?

First Peter 3:15 says Christians must be “ready at any time to give a defense to anyone who asks you for a reason for the hope that is in you.” Simply put, that’s apologetics. But in this short description, we discover three important details.

Doing apologetics means playing defense. The Greek word for “defense” is apologia , from which we get the word apologetics. Think about a football game. At any time during the game, one team is trying to score (the offense) while the other is trying to stop them (the defense). If your team has a really bad defense, you’ll get blown away. Similarly, maybe you’ve been roughed up by some really tough objections to Christianity. You’ve heard the challenges before. “How can a good God allow suffering?” “The Bible is full of errors.” “Jesus can’t be the only way to God.” Apologetics helps us defend Christianity against tough questions like these.

Doing apologetics means playing offense.Back to the football analogy. A good defense is vital but you can’t win if you don’t score. The offense must advance the ball to score points. In the same way, apologetics attempts to give a reason for our hope by advancing arguments in favor of Christianity. We offer evidence for God’s existence, reasons to trust the Bible, and arguments for the bodily resurrection of Jesus. By playing offense, we give nonbelievers good reasons to decide that Christianity is true.

Doing apologetics means giving hope. What are you defending and giving evidence for? “The hope that is in you” (1Pt 3:15). Ultimately, apologetics points people to our hope, Jesus himself. That’s why “we demolish arguments and every proud thing that is raised up against the knowledge of God, and we take every thought captive to obey Christ” (2Co 10:4-5). Objections raised against Jesus must be demolished. But notice something. The Bible doesn’t say we demolish people. Rather, we demolish false arguments . Belittling others is not our goal. Merely winning arguments is not enough. Instead, we remove obstacles of doubt to Christianity so people can take a serious look at Christ, the only source of hope for this world. True apologetics is hopeful.

Further illustrating this point, notice that our earlier quote of 1Pt 3:15 is sandwiched between two important sentences. Peter starts the verse with a challenge: “in your hearts regard Christ the Lord as holy. . .” Apologetics should be done amidst a certain kind of life, one where we surrender more and more to Christ. When we do this, he transforms us. So a transformed life is the beginning point for our apologetics. What will this kind of apologetic look like? Defense doesn’t mean being defensive , and offense doesn’t mean being offensive . Rather, v. 16 tells us our defense is made “with gentleness and respect.” Doing apologetics with Jesus as Lord and Master of our lives means our encounters will be marked by humility, warmth, grace, and love even while we stand boldly for the truth. By doing so, we follow in the way of Jesus, who was “full of grace and truth” (Jn 1:14).

TWISTED SCRIPTURE

1 Peter 3:15-16

Does Peter’s command to “be ready at any time to give a defense” mean that Christianity is based on suspect claims, forcing us to be defensive about our beliefs? The word for “defense” is apologia. It does not mean the same thing as our modern word “apology,” which implies that you are sorry for something you’ve said or done. Instead, apologia means to make an argued defense for your beliefs. Hence Christian apologetics is the reasoned defense of the Bible and the Christian faith. This means explaining to non-Christians that Christianity is based on historically true events such as the resurrection of Jesus Christ. There are many complex questions that can arise when defending Christianity and so careful study is necessary. And in all cases we are commanded to use “gentleness and respect” (v. 16) and to speak “the truth in love” when trying to convince others to become Christians (Eph 4:15). As Christians we can be confident about the foundations of our faith. After all, a faith not worth defending is a faith not worth having!

TWISTED SCRIPTURE

1 Peter 4:6

According to the Mormon interpretation of this verse, a person can accept the gospel even after death. For this reason, living Mormons gather in Mormon temples and perform rituals on behalf of their deceased non-believing relatives. This allows the deceased to escape “Spirit Prison” and enter one of three kingdoms in the Mormon heaven. Is this what Peter had in mind? Context (vv. 3-5) shows that Peter first discussed living persons whose evil lives were causing problems for the Christians to whom he wrote. As Peter makes clear, they will face God’s judgment. He then explained that those who were already dead had the truth preached to them when they were alive. As for Peter’s statement in 3:19 that Jesus “made proclamation to the spirits in prison,” interpreters struggle to know exactly what is meant, but it is clear that the text does not say these spirits had a chance to accept the gospel and escape judgment. Elsewhere the Bible indicates that there can be no salvation after death (Lk 16:19-31; 2Co 6:2; Heb 9:27).

ESV

Responding to Suffering in a Godly Way. Believers are to endure hardship, knowing that they will receive a final reward (3:13–17). Christ suffered at his death but was raised from the dead, and thus has triumphed over all demonic powers (3:18–22). Christians are urged to give themselves wholly to God, being willing to suffer and do what is right (4:1–6). Expectation of the end times should motivate believers to live in a way that pleases God and to exercise their spiritual gifts (4:7–11).

CSB

Did Peter commend unrighteousness in directing wives to submit to their husbands? It may sound that way to modern ears, but submission to another does not signal inequality. The Scriptures clearly teach that women and men are both made in the image of God (Gn 1:26-27); they have equal access to salvation (Gl 3:28); and they share an equal destiny in heaven (1Pt 3:7). Having a different role from men does not mean that women are inferior to men. Christ, after all, submitted to the Father (1Co 15:28), but he is equal to the Father in dignity, worth, and essence. Similarly, the submission of wives to husbands does not suggest they are second-rate.

ESV

Husbands are to be the leaders in their homes (cf. Eph. 5:22–33; Col. 3:18–19), and wives are to be subject to (cf. 1 Pet. 3:5–6) and follow their leadership. If a wife has an unbelieving husband who is disobedient to the word (i.e., the gospel), she should not try to pressure him into converting. Instead, her godly conduct will testify without a word to the truth of the gospel. your own husbands. Scripture never says that women in general are to be subject to men in general, but it does affirm male headship in the home (see also Titus 2:5) and in the church (see notes on 1 Tim. 2:11–15; 3:2–3). Scripture also affirms the equality of man and woman as being made in the image of God (Gen. 1:27; cf. 1 Pet. 3:7).

ESV

For a Christian wife to have a different religion than her husband was quite astonishing for that culture. For example, the Greek historian Plutarch (c. A.D. 46–127) said, “A wife should not acquire her own friends, but should make her husband’s friends her own. The gods are the first and most significant friends. For this reason, it is proper for a wife to recognize only those gods whom her husband worships” (Advice to Bride and Groom 19, Moralia 140D). Even though Peter calls on wives to submit to their husbands, it was a different submission than was common in that culture, for the wives’ devotion was first and foremost to Christ.

ESV

Do not let your adorning be external. Peter’s instructions here were common in his day (see Seneca, Epistles, To Helvia 16.3–4; Dio Chrysostom, Orations 7.117; Juvenal, Satire 6.457–463; 490–511; Plutarch, Advice to Bride and Groom, Moralia 141E; Epictetus, Handbook 40). Such “external … adorning” can be witnessed in portraits and sculptures from the first century, where the elaborate braiding of women’s hair and the wearing of ostentatious jewelry was common in upper-class Roman society. In contrast to this, the Christian woman should focus on inner (hidden) beauty of the heart. What matters to God is the godly character of the wife, characterized by a gentle and quiet spirit. It is clear that Peter is not literally prohibiting all braiding of hair or all wearing of gold jewelry, because if this were the case the same prohibition would apply also to wearing clothing! Instead, Peter warns against both an inordinate preoccupation with personal appearance and material excess in such matters.

ESV

Hope in God is expressed in a wife honoring her husband by submitting to him, as the venerable women in the OT did.

ESV

Sarah obeyed Abraham. Peter describes Sarah’s submission in terms of obedience. Such obedience does not mean the relationship between husbands and wives is like that of parents and children, but it does show that a wife is to follow her husband’s direction and leadership. In the culture of her day, Sarah expressed her submission by respectfully referring to Abraham as lord (see Gen. 18:12). do not fear. Peter calls on wives to model themselves after such godly women, not fearing that harm will come to them, but trusting God as Sarah did.

ESV

Peter’s advice to husbands is compressed, perhaps because he addresses at more length those under authority who are more likely to be mistreated (slaves and wives). The word likewise is merely a transition (cf. v. 1; 5:5); it does not mean husbands should submit to their wives, since Scripture never teaches this (see Eph. 5:21–33). To live … in an understanding way probably focuses on living in accord with God’s will, which includes understanding the needs of a wife. Interpreters differ over whether weaker vessel means weaker in terms of delegated authority, emotions, or physical strength. Peter is probably thinking of the general truth that men are physically stronger than women and may be tempted to threaten their wives through physical or verbal abuse. Women and men share an equal destiny as heirs … of the grace of life. Peter does not think women are inferior to men, for both are equally made in God’s image (cf. Gal. 3:28). If husbands do not treat their wives in a godly way, the Lord will pay no heed to their prayers.

ESV

Finally, all of you provides a transition from the preceding specific instructions to a list of godly virtues that all believers are called to exemplify at all times. Those who bless others will receive a blessing from God, which Peter explains in the following verses.

ESV

Peter draws on Ps. 34:12–16 (see note on 1 Pet. 2:3). To love life and see good days is the result of the “blessing” (3:9) of God in one’s life. Peter says this will come to the person who will keep his tongue from evil and who will turn away from evil and do good. Obedience to God in daily life is the path to experiencing God’s blessing (cf. Ps. 34:4–10), and by implication disobedience will lead to God’s discipline (cf. Ps. 34:16, 21; Heb. 12:4–11). Peter continues his quotation of Psalm 34: For the eyes of the Lord are on the righteous (to observe and care for them) and his ears are open to their prayer (for various needs and cares). This does not mean that God keeps obedient believers from suffering (cf. 1 Pet. 2:19–23; 3:14, 17; 4:12–19) but that God will provide his grace “to strengthen and establish” believers in the midst of suffering (5:10) and in times of great need (cf. 2 Cor. 12:9; Heb. 4:16).

ESV

even if. Peter is writing to Christians already suffering for their faith, therefore he is not saying that such suffering is improbable. His point is that no one will ultimately or finally harm Christians, “even if” they suffer now, for God will reward them (cf. Rom. 8:31). Indeed, they will be blessed by God in their sufferings (cf. Matt. 5:10).

CSB

“Defense” in v. 15 is the Greek word apologia, from which we get our term “apologetics.” These verses are crucial for understanding how apologetics should be carried out: (1) with faith and “hope” in Christ as Lord; (2) with prior preparation, so that we are always “ready;” (3) through rational and logical “defense” of the truth; (4) with “gentleness and respect,” meaning truth should be explained winsomely as errors are refuted; and (5) with “a clear conscience” so that our conduct corroborates rather than undermines the truth.

ESV

Believers should always be ready to provide a rationale for their faith, but they should do so winsomely and righteously. And if they keep a good conscience, any accusations against them will prove groundless, and their accusers will be put to shame. It is sometimes God’s will that Christians suffer for doing good.

ESV

A key statement on the substitutionary atonement of Christ. He suffered and died as the righteous one in place of the unrighteous, in order to bring us to God. One interpretation of being put to death in the flesh but made alive in the spirit is that “in the flesh” means in the visible, physical realm in which Jesus was crucified and “in the spirit” (as in 4:6) means in the invisible, spiritual realm where Christ now lives. Another view is that Jesus died physically but was raised from the dead by the Holy Spirit.

ESV

spirits in prison. There is much debate about the identity of these spirits. The Greek term pneuma (“spirit”), in either singular or plural, can mean either human spirits or angels, depending on the context (cf. Num. 16:22; 27:16; Acts 7:59; Heb. 12:23; etc.). Among the three most common interpretations, the first two fit best with the rest of Scripture and with historic orthodox Christian doctrine. These are:

(1) The first interpretation understands “spirits” (Gk. pneumasin, plural) as referring to the unsaved (human spirits) of Noah’s day. Christ, “in the spirit” (1 Pet. 3:18), proclaimed the gospel “in the days of Noah” (v. 20) through Noah. The unbelievers who heard Christ’s preaching “did not obey … in the days of Noah” (v. 20) and are now suffering judgment (they are “spirits in prison,” v. 19). Several reasons support this view: (a) Peter calls Noah a “herald of righteousness” (2 Pet. 2:5), where “herald” represents Greek kēryx, “preacher,” which corresponds to the noun kēryssō, “proclaim,” in 1 Pet. 3:19. (b) Peter says the “Spirit of Christ” was speaking through the OT prophets (1:11); thus Christ could have been speaking through Noah as an OT prophet. (c) The context indicates that Christ was preaching through Noah, who was in a persecuted minority, and God saved Noah, which is similar to the situation in Peter’s time: Christ is now preaching the gospel through Peter and his readers (v. 15) to a persecuted minority, and God will save them.

(2) In the second interpretation, the spirits are the fallen angels who were cast into hell to await the final judgment. Reasons supporting this view include: (a) Some interpreters say that the “sons of God” in Gen. 6:2–4 are angels (see note on Gen. 6:1–2) who sinned by cohabiting with human women “when God’s patience waited in the days of Noah” (1 Pet. 3:20). (b) Almost without exception in the NT, “spirits” (plural) refers to supernatural beings rather than people (e.g., Matt. 8:16; 10:1; Mark 1:27; 5:13; 6:7; Luke 4:36; 6:18; 7:21; 8:2; 10:20; 11:26; Acts 5:16; 8:7; 19:12, 13; 1 Tim. 4:1; 1 John 4:1; Rev. 16:13–14; cf. Heb. 1:7). (c) The word “prison” is not used elsewhere in Scripture as a place of punishment after death for human beings, while it is used for Satan (Rev. 20:7) and other fallen angels (2 Pet. 2:4; Jude 6). In this case the message that Christ proclaimed is almost certainly one of triumph, after having been “put to death in the flesh but made alive in the spirit” (1 Pet. 3:18).

(3) In a third view, some have advocated the idea that Christ offered a second chance of salvation to those in hell. This interpretation, however, is in direct contradiction with other Scripture (cf. Luke 16:26; Heb. 9:27) and with the rest of 1 Peter and therefore must be rejected on biblical and theological grounds, leaving either of the first two views as the most likely interpretation.

ESV

A comparison is drawn between salvation in the ark and baptism. In both instances, believers are saved through the waters of judgment, since baptism portrays salvation through judgment. The mere mechanical act of baptism does not save, for Peter explicitly says, “not as a removal of dirt from the body,” meaning that the passing of water over the body does not cleanse anyone. Baptism saves you because it represents inward faith, as evidenced by one’s appeal to God for the forgiveness of one’s sins (for a good conscience). Furthermore, baptism “saves” only insofar as it is grounded in the death and resurrection of Jesus Christ. Baptism is a visual representation of the fact that Christians are clothed with Christ (cf. Gal. 3:27), and in union with Christ they share his victory over sin. Though Christians have disagreed about the proper mode of water baptism beginning in the early history of the church, Christians have generally agreed (irrespective of denominational differences) that water baptism is an outward sign of the inward reality of regeneration, which is the result of the work of the Holy Spirit (cf. John 3:5, 8; Titus 3:5), and which may be received only by grace through faith (see Eph. 2:8).

ESV

The central truth of vv. 18–22 is that Christ has triumphed over his enemies. He is now ascended to the right hand of God, and all angels and demonic powers are subjected to him since he is Lord and Christ. Christians can therefore rejoice in their sufferings, knowing that Christ has triumphed.
