For you are all sons of light and sons of the day; we are not of the night or of darkness. So then let us not sleep, as others do, but let us keep awake and be sober. For those who sleep at night, and those who get drunk are drunk at night. But, since we belong to the day, let us be sober, and put on the breastplate of faith and love, and for a helmet the hope of salvation.
1 Thessalonians 5:5-8 RSV
