1 Thessalonians 5

4 But ye, brethren, are not in darkness, that the day should overtake you as a thief: 5 for all ye are sons of light and sons of day; we are not of night nor of darkness.

6 So then do not let us sleep as the rest do, but let us watch and be sober; 7 for they that sleep sleep by night, and they that drink drink by night; 8 but we being of the day, let us be sober, putting on the breastplate of faith and love, and as helmet the hope of salvation; 9 because God has not set us for wrath, but for obtaining salvation through our Lord Jesus Christ,
