1 Peter

1Chapter

Greeting

1Peter, an apostle of Jesus Christ, To those who are elect exiles of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia, 2according to the foreknowledge of God the Father, in the sanctification of the Spirit, for obedience to Jesus Christ and for sprinkling with his blood: May grace and peace be multiplied to you.

Born Again to a Living Hope

3Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, 4to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, 5who by God's power are being guarded through faith for a salvation ready to be revealed in the last time. 6In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, 7so that the tested genuineness of your faith—more precious than gold that perishes though it is tested by fire—may be found to result in praise and glory and honor at the revelation of Jesus Christ. 8Though you have not seen him, you love him. Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory, 9obtaining the outcome of your faith, the salvation of your souls.
10Concerning this salvation, the prophets who prophesied about the grace that was to be yours searched and inquired carefully, 11inquiring what person or time the Spirit of Christ in them was indicating when he predicted the sufferings of Christ and the subsequent glories. 12It was revealed to them that they were serving not themselves but you, in the things that have now been announced to you through those who preached the good news to you by the Holy Spirit sent from heaven, things into which angels long to look.

Called to Be Holy

13Therefore, preparing your minds for action, and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ. 14As obedient children, do not be conformed to the passions of your former ignorance, 15but as he who called you is holy, you also be holy in all your conduct, 16since it is written, “You shall be holy, for I am holy.” 17And if you call on him as Father who judges impartially according to each one's deeds, conduct yourselves with fear throughout the time of your exile, 18knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold, 19but with the precious blood of Christ, like that of a lamb without blemish or spot. 20He was foreknown before the foundation of the world but was made manifest in the last times for the sake of you 21who through him are believers in God, who raised him from the dead and gave him glory, so that your faith and hope are in God.
22Having purified your souls by your obedience to the truth for a sincere brotherly love, love one another earnestly from a pure heart, 23since you have been born again, not of perishable seed but of imperishable, through the living and abiding word of God; 24“All flesh is like grass and all its glory like the flower of grass. The grass withers, and the flower falls,
25but the word of the Lord remains forever.” And this word is the good news that was preached to you.
2Chapter

A Living Stone and a Holy People

1So put away all malice and all deceit and hypocrisy and envy and all slander. 2Like newborn infants, long for the pure spiritual milk, that by it you may grow up into salvation— 3if indeed you have tasted that the Lord is good.
4As you come to him, a living stone rejected by men but in the sight of God chosen and precious, 5you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. 6“Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.”
7“The stone that the builders rejected has become the cornerstone,”
8“A stone of stumbling, and a rock of offense.” They stumble because they disobey the word, as they were destined to do.
9But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. 10Once you were not a people, but now you are God's people; once you had not received mercy, but now you have received mercy.
11Beloved, I urge you as sojourners and exiles to abstain from the passions of the flesh, which wage war against your soul. 12Keep your conduct among the Gentiles honorable, so that when they speak against you as evildoers, they may see your good deeds and glorify God on the day of visitation.

Submission to Authority

13Be subject for the Lord's sake to every human institution, whether it be to the emperor as supreme, 14or to governors as sent by him to punish those who do evil and to praise those who do good. 15For this is the will of God, that by doing good you should put to silence the ignorance of foolish people. 16Live as people who are free, not using your freedom as a cover-up for evil, but living as servants of God. 17Honor everyone. Love the brotherhood. Fear God. Honor the emperor.
18Servants, be subject to your masters with all respect, not only to the good and gentle but also to the unjust. 19For this is a gracious thing, when, mindful of God, one endures sorrows while suffering unjustly. 20For what credit is it if, when you sin and are beaten for it, you endure? But if when you do good and suffer for it you endure, this is a gracious thing in the sight of God. 21For to this you have been called, because Christ also suffered for you, leaving you an example, so that you might follow in his steps. 22He committed no sin, neither was deceit found in his mouth. 23When he was reviled, he did not revile in return; when he suffered, he did not threaten, but continued entrusting himself to him who judges justly. 24He himself bore our sins in his body on the tree, that we might die to sin and live to righteousness. By his wounds you have been healed. 25For you were straying like sheep, but have now returned to the Shepherd and Overseer of your souls.
3Chapter

Wives and Husbands

1Likewise, wives, be subject to your own husbands, so that even if some do not obey the word, they may be won without a word by the conduct of their wives, 2when they see your respectful and pure conduct. 3Do not let your adorning be external—the braiding of hair and the putting on of gold jewelry, or the clothing you wear— 4but let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God's sight is very precious. 5For this is how the holy women who hoped in God used to adorn themselves, by submitting to their own husbands, 6as Sarah obeyed Abraham, calling him lord. And you are her children, if you do good and do not fear anything that is frightening.
7Likewise, husbands, live with your wives in an understanding way, showing honor to the woman as the weaker vessel, since they are heirs with you of the grace of life, so that your prayers may not be hindered.

Suffering for Righteousness' Sake

8Finally, all of you, have unity of mind, sympathy, brotherly love, a tender heart, and a humble mind. 9Do not repay evil for evil or reviling for reviling, but on the contrary, bless, for to this you were called, that you may obtain a blessing. 10“Whoever desires to love life and see good days, let him keep his tongue from evil and his lips from speaking deceit;
11let him turn away from evil and do good; let him seek peace and pursue it.
12For 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 evil.”
13Now who is there to harm you if you are zealous for what is good? 14But even if you should suffer for righteousness' sake, you will be blessed. Have no fear of them, nor be troubled, 15but in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect, 16having a good conscience, so that, when you are slandered, those who revile your good behavior in Christ may 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 once for sins, the righteous for the unrighteous, that he might bring us to God, being put to death in the flesh but made alive in the spirit, 19in which he went and proclaimed to the spirits in prison, 20because they formerly did not obey, when God's patience waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight persons, were brought safely through water. 21Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ, 22who has gone into heaven and is at the right hand of God, with angels, authorities, and powers having been subjected to him.
4Chapter

Stewards of God's Grace

1Since therefore Christ suffered in the flesh, arm yourselves with the same way of thinking, for whoever has suffered in the flesh has ceased from sin, 2so as to live for the rest of the time in the flesh no longer for human passions but for the will of God. 3For the time that is past suffices for doing what the Gentiles want to do, living in sensuality, passions, drunkenness, orgies, drinking parties, and lawless idolatry. 4With respect to this they are surprised when you do not join them in the same flood of debauchery, and they malign you; 5but they will give account to him who is ready to judge the living and the dead. 6For this is why the gospel was preached even to those who are dead, that though judged in the flesh the way people are, they might live in the spirit the way God does.
7The end of all things is at hand; therefore be self-controlled and sober-minded for the sake of your prayers. 8Above all, keep loving one another earnestly, since love covers a multitude of sins. 9Show hospitality to one another without grumbling. 10As each has received a gift, use it to serve one another, as good stewards of God's varied grace: 11whoever speaks, as one who speaks oracles of God; whoever serves, as one who serves by the strength that God supplies—in order that in everything God may be glorified through Jesus Christ. To him belong glory and dominion forever and ever. Amen.

Suffering as a Christian

12Beloved, do not be surprised at the fiery trial when it comes upon you to test you, as though something strange were happening to you. 13But rejoice insofar as you share Christ's sufferings, that you may also rejoice and be glad when his glory is revealed. 14If you are insulted for the name of Christ, you are blessed, because the Spirit of glory and of God rests upon you. 15But let none of you suffer as a murderer or a thief or an evildoer or as a meddler. 16Yet if anyone suffers as a Christian, let him not be ashamed, but let him glorify God in that name. 17For it is time for judgment to begin at the household of God; and if it begins with us, what will be the outcome for those who do not obey the gospel of God? 18“If the righteous is scarcely saved, what will become of the ungodly and the sinner?”
19Therefore let those who suffer according to God's will entrust their souls to a faithful Creator while doing good.
5Chapter

Shepherd the Flock of God

1So I exhort the elders among you, as a fellow elder and a witness of the sufferings of Christ, as well as a partaker in the glory that is going to be revealed: 2shepherd the flock of God that is among you, exercising oversight, not under compulsion, but willingly, as God would have you; not for shameful gain, but eagerly; 3not domineering over those in your charge, but being examples to the flock. 4And when the chief Shepherd appears, you will receive the unfading crown of glory. 5Likewise, you who are younger, be subject to the elders. Clothe yourselves, all of you, with humility toward one another, for “God opposes the proud but gives grace to the humble.”
6Humble yourselves, therefore, under the mighty hand of God so that at the proper time he may exalt you, 7casting all your anxieties on him, because he cares for you. 8Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour. 9Resist him, firm in your faith, knowing that the same kinds of suffering are being experienced by your brotherhood throughout the world. 10And after you have suffered a little while, the God of all grace, who has called you to his eternal glory in Christ, will himself restore, confirm, strengthen, and establish you. 11To him be the dominion forever and ever. Amen.

Final Greetings

12By Silvanus, a faithful brother as I regard him, I have written briefly to you, exhorting and declaring that this is the true grace of God. Stand firm in it. 13She who is at Babylon, who is likewise chosen, sends you greetings, and so does Mark, my son. 14Greet one another with the 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.
