Ephesians 5:7-11 New Revised Standard Version (NRSV)
7 Therefore do not be associated with them. 8 For once you were darkness, but now in the Lord you are light. Live as children of light— 9 for the fruit of the light is found in all that is good and right and true. 10 Try to find out what is pleasing to the Lord. 11 Take no part in the unfruitful works of darkness, but instead expose them.
