1 Thessalonians 5:6-8 (NLT)

6Therefore let us not sleep, as do others; but let us watch and be sober.

7For they that sleep sleep in the night; and they that be drunken are drunken in the night.

8But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation.
