5 Now concerning how and when all this will happen, dear brothers and sisters,^[a] 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.

⁴ But 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.^{[b] 5} For you are all children of the light and of the day; we don’t belong to darkness and night. ⁶ So be on your guard, not asleep like the others. Stay alert and be clearheaded. ⁷ Night is the time when people sleep and drinkers get drunk. ⁸ But let us who live in the light be clearheaded, protected by the armor of faith and love, and wearing as our helmet the confidence of our salvation.

⁹ For God chose to save us through our Lord Jesus Christ, not to pour out his anger on us. ¹⁰ Christ died for us so that, whether we are dead or alive when he returns, we can live with him forever. ¹¹ So encourage each other and build each other up, just as you are already doing.
