41 Since therefore Christ suffered in the flesh, arm yourselves also with the same intention (for whoever has suffered in the flesh has finished with sin), 2 so as to live for the rest of your earthly life no longer by human desires but by the will of God. 3 You have already spent enough time in doing what the Gentiles like to do, living in licentiousness, passions, drunkenness, revels, carousing, and lawless idolatry.
4 They are surprised that you no longer join them in the same excesses of dissipation, and so they blaspheme. 5 But they will have to give an accounting to him who stands ready to judge the living and the dead. 6 For this is the reason the gospel was proclaimed even to the dead, so that, though they had been judged in the flesh as everyone is judged, they might live in the spirit as God does.
Matthew Henry's Commentary on 1 Peter 4:1-6
Commentary on 1 Peter 4:1-6
(Read 1 Peter 4:1-6)
The strongest and best arguments against sin, are taken from the sufferings of Christ. He died to destroy sin; and though he cheerfully submitted to the worst sufferings, yet he never gave way to the least sin. Temptations could not prevail, were it not for man's own corruption; but true Christians make the will of God, not their own lust or desires, the rule of their lives and actions. And true conversion makes a marvellous change in the heart and life. It alters the mind, judgment, affections, and conversation. When a man is truly converted, it is very grievous to him to think how the time past of his life has been spent. One sin draws on another. Six sins are here mentioned which have dependence one upon another. It is a Christian's duty, not only to keep from gross wickedness, but also from things that lead to sin, or appear evil. The gospel had been preached to those since dead, who by the proud and carnal judgment of wicked men were condemned as evil-doers, some even suffering death. But being quickened to Divine life by the Holy Spirit, they lived to God as his devoted servants. Let not believers care, though the world scorns and reproaches them.
