Ephesians 5:11-14 (KJV)
11 And have no fellowship with the unfruitful works of darkness, but rather reprove them.
12 For it is a shame even to speak of those things which are done of them in secret.
13 But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light.
14 Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.
