1 Peter 4:2

Peter clarified commitment to God’s will in this verse. "Flesh" refers to one’s mortal lifetime on earth, not to carnal living (cf. 1 Peter 3:18; 1 Peter 4:6).

". . . ’the flesh’ is not used here or anywhere else in 1 Peter (it is used seven times; all but one of them are in 1 Peter 3:18 to 1 Peter 4:6) in the Pauline sense of the sinful nature in human beings (as, e.g., in Romans 7-8), but in the normal Jewish sense of human existence as weak, fallen, and therefore subject to pain and death." [Note: Davids, p. 150.]

"We may not always understand what He [God] is doing, but we know that He is doing what is best for us. We do not live on explanations; we live on promises." [Note: Wiersbe, 2:420.]
