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.
– 1 Thessalonians 5:4-7
