1 Thessalonians 5:1-4

The Day of the Lord

Now concerning the times and the seasons, brothers, you have no need to have anything written to you.
2 For you yourselves are fully aware that the day of the Lord will come like a thief in the night. 3 While people are saying, “There is peace and security,” then sudden destruction will come upon them as labor pains come upon a pregnant woman, and they will not escape. 4 But you are not in darkness, brothers, for that day to surprise you like a thief.
