1 Thessalonians 5:4-8

4But you, brothers and sisters, are not in the dark, so that the Day might overtake you like a thief.

5For you all are sons of light and sons of day. We are not of night or of darkness—

6so then, let us not sleep as the others do, but let us remain on the alert and sober-minded.

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

8But since we are of the day, let us be sober-minded—putting on the breastplate of faithfulness and love, and the hope of salvation as a helmet.
