Ephesians 5:8-16

for ye were once darkness, but are now light in the Lord: walk as children of light (for the fruit of the light is in all goodness and righteousness and truth), proving what is well-pleasing unto the Lord; and have no fellowship with the unfruitful works of darkness, but rather even reprove them; for the things which are done by them in secret it is a shame even to speak of. But all things when they are reproved are made manifest by the light: for everything that is made manifest is light. Wherefore he saith, Awake, thou that sleepest, and arise from the dead, and Christ shall shine upon thee. Look therefore carefully how ye walk, not as unwise, but as wise; redeeming the time, because the days are evil.
