Ephesians 5:8-13

8for ye were once darkness, but are now light in the Lord: walk as children of light 9(for the fruit of the light is in all goodness and righteousness and truth), 10proving what is well-pleasing unto the Lord; 11and have no fellowship with the unfruitful works of darkness, but rather even reprove them; 12for the things which are done by them in secret it is a shame even to speak of. 13But all things when they are reproved are made manifest by the light: for everything that is made manifest is light.
