1 Thessalonians 5:2-8

For you yourselves know very well that the day of the Lord will come just like a thief in the night. When they say, “Peace and security,” then sudden destruction will come upon them, like labor pains on a pregnant woman, and they will not escape. But you, brothers and sisters, are not in the dark, for this day to surprise you like a thief. For you are all children of light and children of the day. We do not belong to the night or the darkness. So then, let us not sleep, like the rest, but let us stay awake and be self-controlled. For those who sleep, sleep at night, and those who get drunk, get drunk at night. But since we belong to the day, let us be self-controlled and put on the armor of faith and love, and a helmet of the hope of salvation.
