1 Thes 5:1-6

Vigilance. 1Concerning times and seasons, brothers, you have no need for anything to be written to you.^a 2For you yourselves know very well that the day of the Lord will come like a thief at night.^b 3When people are saying, “Peace and security,” then sudden disaster comes upon them, like labor pains upon a pregnant woman, and they will not escape.

4But you, brothers, are not in darkness, for that day to overtake you like a thief.^c 5For all of you are children of the light^* and children of the day. We are not of the night or of darkness. 6Therefore, let us not sleep as the rest do, but let us stay alert and sober.^d
