1 Thessalonians 5:2-6

For you yourselves know full well that the day of the Lord is coming just like a thief in the night.

While they are saying, “Peace and safety!” then sudden destruction will come upon them like labor pains upon a pregnant woman, and they will not escape.

But you, brothers and sisters, are not in darkness, so that the day would overtake you like a thief;

for you are all sons of light and sons of day. We are not of night nor of darkness;

so then, let’s not sleep as others do, but let’s be alert and sober.
