1 Thessalonians 5:2-8 (New King James Version)

² For you yourselves know perfectly that the day of the Lord so comes as a thief in the night. ³ For when they say, “Peace and safety!” then sudden destruction comes upon them, as labor pains upon a pregnant woman. And they shall not escape. ⁴ But you, brethren, are not in darkness, so that this Day should overtake you as a thief. ⁵ You are all sons of light and sons of the day. We are not of the night nor of darkness. ⁶ Therefore let us not sleep, as others do, but let us watch and be sober. ⁷ For those who sleep, sleep at night, and those who get drunk are drunk at night. ⁸ But let us who are of the day be sober, putting on the breastplate of faith and love, and as a helmet the hope of salvation.
