1 Thessalonians 5:4-7

5:4 But you, brothers and sisters, are not in the darkness for the day to overtake you like a thief would. 5:5 For you all are sons of the light and sons of the day. We are not of the night nor of the darkness. 5:6 So then we must not sleep as the rest, but must stay alert and sober. 5:7 For those who sleep, sleep at night and those who get drunk are drunk at night.
