1 Thessalonians 5:4-7

4But you, brothers and sisters, are not in the dark, for this day to surprise you like a thief.

5For you are all children of light and children of the day. We do not belong to the night or the darkness.

6So then, let us not sleep, like the rest, but let us stay awake and be self-controlled.

7For those who sleep, sleep at night, and those who get drunk, get drunk at night.
