1 Thessalonians 5:2-5

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.
