1 Now concerning how and when all this will happen, dear brothers and sisters,*5:1 Greek brothers; also in 5:4, 12, 14, 25, 26, 27. we don’t really need to write you. 2 For you know quite well that the day of the Lord’s return will come unexpectedly, like a thief in the night. 3 When people are saying, "Everything is peaceful and secure," then disaster will fall on them as suddenly as a pregnant woman’s labor pains begin. And there will be no escape.
