1 Therefore, since Christ suffered for us in the flesh, arm yourselves also with the same mind, for he who has suffered in the flesh has ceased from sin, 2 that he no longer should live the rest of his time in the flesh for the lusts of men, but for the will of God. (1 Peter 4:1–2, NKJV)
Christ suffered for us; “the just for the unjust, that He might bring us to God” (1 Pet. 3:18). His suffering in the flesh compels Christians to equip ourselves with His mind or attitude; the decision to do good and, if need be, “to suffer for doing good” (1 Pet. 3:17; 4:1). Contrary to the “health and wealth gospel” taught by false teachers, being a Christian does not free one from suffering. The devoted Christian accepts a life of suffering for doing the will of God. In verse two, Peter says such suffering includes no longer living to fulfill the lusts of the flesh. Our devotion is to the will of God. Even when your former companions in sin think you are odd, and speak evil of you for no longer joining them in sin, remember that you have “ceased from sin” and cannot continue to practice it (1 Pet. 4:3-4, 1). Peer pressure is powerful, but we must see it for what it is; the attempt of sinful people to draw us into sinning along with them. Resist. Suffer (when it comes to that). Live for the will of God. Do not live for the lusts of men.
