Peter begins with the example of Christ. Since Christ suffered in the flesh, believers should arm themselves with the same mind. They should live the rest of their time not for human lusts, but for the will of God. They have already spent enough time on the ways of the nations. Former friends think it strange that they no longer run with them into the same excess, and they speak evil of them. Yet everyone will give account to him who is ready to judge the living and the dead.
Because the end of all things is near, Peter calls for a sober and loving community. Be of sound mind, self-controlled, and sober in prayer. And above all things be earnest in your love among yourselves, for love covers a multitude of sins. Be hospitable to one another without grumbling. As each has received a gift, employ it in serving one another, as good managers of the grace of God in its various forms. Speaking and serving gifts both come from God, so that in all things God may be glorified through Jesus Christ.
Peter then speaks frankly about suffering. Beloved, don’t be astonished at the fiery trial which has come upon you to test you, as though a strange thing happened to you. They share in Christ’s sufferings, and if they are insulted for the name of Christ, they are blessed, because the Spirit of glory rests on them. A believer should never suffer as a wrongdoer or a meddler. But if one of you suffers for being a Christian, let him not be ashamed; but let him glorify God in this matter. Judgment begins with the household of God. Those who suffer according to God’s will should entrust their souls to a faithful Creator in doing good.
