1 Thessalonians 5:4-8

WNT(i) 4 But you, brethren, are not in darkness, that daylight should surprise you like a thief; 5 for all of you are sons of Light and sons of the day. We belong neither to the night nor to darkness. 6 So then let us not sleep, like the rest of the world, but let us keep awake and be sober. 7 For those who sleep, sleep at night, and those who drink freely, drink at night. 8 But let us, belonging--as we do--to the day, be sober, putting on the breastplate of faith and love, and for a helmet the hope of salvation.
