1Now 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. 2For you know quite well that the day of the Lord’s return will come unexpectedly, like a thief in the night. 3When 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. 4But you aren’t in the dark about these things, dear brothers and sisters, and you won’t be surprised when the day of the Lord comes like a thief.#5:4 Some manuscripts read comes upon you as if you were thieves. 5For you are all children of the light and of the day; we don’t belong to darkness and night. 6So be on your guard, not asleep like the others. Stay alert and be clearheaded. 7Night is the time when people sleep and drinkers get drunk.
