1 Thessalonians 5:1-6

Revised Standard Version Catholic Edition

5 But as to the times and the seasons, brethren, you have no need to have anything written to you. ² For you yourselves know well that the day of the Lord will come like a thief in the night. ³ When people say, “There is peace and security,” then sudden destruction will come upon them as travail comes upon a woman with child, and there will be no escape. ⁴ But you are not in darkness, brethren, for that day to surprise you like a thief. ⁵ For you are all sons of light and sons of the day; we are not of the night or of darkness. ⁶ So then let us not sleep, as others do, but let us keep awake and be sober.
