John Calvin Commentary 1 Peter 4:2

"that ye no longer should live the rest of your time in flesh to the lusts of men, but to the will of God." — 1 Peter 4:2 (ASV)

That he no longer. Here he sets forth the way to cease from sin: that renouncing the covetings of men, we should strive to conform our lives to the will of God. Thus, he includes here the two things in which renovation consists: the destruction of the flesh and the vivification of the spirit. The course of good living, therefore, is to begin with the former, but we are to advance to the latter.

Moreover, Peter here defines the rule of right living: that a person is to depend on the will of God. Therefore, it follows that nothing is right and well-ordered in a person’s life when he wanders from this rule. Furthermore, we should notice the contrast between God’s will and the covetings or lusts of men. From this, we understand how great our depravity is, and how we ought to strive to become obedient to God. When he says, the rest of time in the flesh, the word flesh means the present life, as in Hebrews 5:7.
