for you are all sons of light and sons of day. We belong neither to night nor to darkness.

1 Thess. 5:4-6.

²¹ Showing what it means to be awake and to prove that we are “sons of day” rather than of darkness, Paul says at Romans 13:11-14: “You people know the season, that it is already the hour for you to awake from sleep, for now our salvation is nearer than at the time when we became believers. The night is well along; the day has drawn near. Let us therefore put off the works belonging to darkness and let us put on the weapons of the light. As in the daytime let us walk decently, not in revelries and drunken bouts, not in illicit intercourse and loose conduct, not in strife and jealousy. But put on the Lord Jesus Christ, and do not be planning ahead for the desires of the flesh.”
