Christ suffered while he was in his body. So you should strengthen yourselves with the same kind of thinking Christ had. The person who has suffered in his body is finished with sin.
In the past you wasted too much time doing the things that the non-believers like to do. You were doing sexual sins. You were doing the evil things you wanted. You were becoming drunk, having wild and wasteful parties, having drunken parties, and doing wrong by worshiping idols (false gods).
