1 Thessalonians 5:2-4

For you already know quite well that the day of the Lord will come unexpectedly and as a complete surprise. For while some are saying, “Finally we have peace and security,” sudden destruction will arrive at their doorstep, like labor pains seizing a pregnant woman—and with no chance of escape! But you, beloved brothers and sisters, are not living in the dark, allowing that day to creep up on you like a thief coming to steal.
