Romans 13:13

honestly Margin, decently, i.e. becomingly; with the true decorumof a life of obedience to the will of God.

as in the day Here again the metaphor slightly varies its point. The Gr. is, nearly lit., as by day; "as men walk by day." The Christian is thus bidden to think of himself as in the daylight; with light on him and around him. This is probably here the "light" of 1 John 1:7; the light of the knowledge of the Holy One, and of His felt presence. (See Psalms 139:12.) Such "light" is the dawning of that Day in which "we shall be like Him, for we shall see Him as He is;" and this accords with the imagery of Romans 13:12.

rioting Cp. Galatians 5:21; 1 Peter 4:3.

drunkenness The Gr. (as in Gal. and 1 Pet. just quoted) is plural; drinking-bouts.

chambering Again plural: indulgences of lustful pleasure.

wantonness Again plural: the varietiesof lascivious sin are suggested.

Such warnings as these, addressed to the justified and believing, not to a mass of merely conventional Christians, are indications of the immense force of moral corruption in the heathen world out of which the Christians had lately come, and which everywhere surrounded them. But they also indicate the permanent fact that the most sincere Christian, in the happiest times, is never in his own strength invulnerable even by gross temptation.

not in strife and envying Sins of the temper are here classed with lusts of the flesh; as often. See e.g. Galatians 5:19-20.
