1 Thessalonians 5:4-8

But ye, brethren, are not in darkness, that that day should overtake you as a thief.

Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.

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

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

But 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.
