1 Thessalonians 5:2-5

2For you yourselves know perfectly that the day of the Lord so comes as a thief in the night.

3For when they say, “Peace and safety!” then sudden destruction comes upon them, as labor pains upon a pregnant woman. And they shall not escape.

4But you, brethren, are not in darkness, so that this Day should overtake you as a thief.

5You are all sons of light and sons of the day. We are not of the night nor of darkness.
