1 Thessalonians 5:4-8

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. For you are all children of the light and of the day; we don’t belong to darkness and night. So be on your guard, not asleep like the others. Stay alert and be clearheaded. Night is the time when people sleep and drinkers get drunk. 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.
