I Peter 4:1-6
1 Therefore, 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—
2 in order to live the remaining time in the flesh no longer for human desires, but for God’s will.
3 For 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.
4 They are surprised that you don’t join them in the same flood of wild living—and they slander you.
5 They will give an account to the one who stands ready to judge the living and the dead.
6 For 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.
Suffering is a regular tool on God’s workbench of sanctification.
