Ephesians 5:14-16

Therefore He says, Awake, O sleeper, and arise from the dead, and Christ shall shine (make day dawn) upon you and give you light. [Isa. 26:19; 60:1, 2.] Look carefully then how you walk! Live purposefully and worthily and accurately, not as the unwise and witless, but as wise (sensible, intelligent people), Making the very most of the time [buying up each opportunity], because the days are evil.
