1 Thessalonians 5:4-6

Holman Christian Standard Bible

⁴ But you, brothers, are not in the dark, for this day to overtake you like a thief.^{(A) 5} For you are all sons of light and sons of the day. We do not belong to the night or the darkness.^{(B) 6} So then, we must not sleep, like the rest, but we must stay awake and be serious.
