1 Thessalonians 5:2-6

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.

6Therefore let us not sleep, as others do, but let us watch and be sober.
