'Day time' in the Bible

for all of you people belong to the light; you belong to the daytime. We do not belong to the night or to darkness. [Note: In this passage "light" and "daytime" refer to spiritual illumination, while "darkness" and "night" refer to spiritual ignorance].

But, since we belong to the daytime [i.e., are enlightened], we should be sober. We should put on the "flack jacket" of faith and love, and for a helmet, the hope of being saved.
