1 Thessalonians 5:2-5

2For you are fully aware that the Day of the Lord will come like a thief in the night. 3While people are saying, “Peace and security,” destruction will come upon them suddenly, like labor pains on a pregnant woman, and they will not escape.

4But you, brothers, are not in the darkness so that this day should overtake you like a thief. 5For you are all sons of the light and sons of the day; we do not belong to the night or to the darkness.
