1 Thessalonians 5:4-8
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.
5:8 But since we are of the day, we must stay sober by putting on the breastplate of faith and love and as a helmet our hope for salvation.
