1 Thessalonians 5:2-8

2For you yourselves are fully aware that the day of the Lord will come like a thief in the night. 3While people are saying, “There is peace and security,” then sudden destruction will come upon them as labor pains come upon a pregnant woman, and they will not escape. 4But you are not in darkness, brothers, for that day to surprise you like a thief. 5For you are all children of light, children of the day. We are not of the night or of the darkness. 6So then let us not sleep, as others do, but let us keep awake and be sober. 7For those who sleep, sleep at night, and those who get drunk, are drunk at night. 8But since we belong to the day, let us be sober, having put on the breastplate of faith and love, and for a helmet the hope of salvation.
