1 Peter 4:1-2
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.
Since Christ suffered in His body, arm yourselves also with the same attitude, because whoever suffers in the body is done with sin.
Since Christ suffered in the flesh and died for us, arm yourselves like warriors with the same purpose being willing to suffer for doing what is right and pleasing God, because whoever has suffered in the flesh being like-minded with Christ is done with intentional sin having stopped pleasing the world.
As a result, they do not live the rest of their earthly lives for evil human desires, but rather for the will of God.
So he can no longer spend the rest of his natural life living for human appetites and desires, but lives for the will and purpose of God.
