For at one time you were darkness,
but now you are light in the Lord. 
Walk as children of light 
(for the 
fruit of light is found in
all that is good and right 
and true), 
and try to discern what is pleasing to
the Lord. 
Take no part in the unfruitful works
of darkness, but instead expose them. 

Ephesians 5:8-10 NASB
