1 Thessalonians 5:1-6

1 There is no need to write you, friends, about the times and occasions when these things will happen.
2 For you yourselves know very well that the Day of the Lord will come as a thief comes at night. 1
3 When people say, "Everything is quiet and safe," then suddenly destruction will hit them! It will come as suddenly as the pains that come upon a woman in labor, and people will not escape.
4 But you, friends, are not in the darkness, and the Day should not take you by surprise like a thief.
5 All of you are people who belong to the light, who belong to the day. We do not belong to the night or to the darkness.
6 So then, we should not be sleeping like the others; we should be awake and sober.
