Ephesians 5:9

6 Do not be turned from the right way by foolish words; for because of these things the punishment of God comes on those who do not put themselves under him.

7 Have no part with such men;

8 For you at one time were dark, but now are light in the Lord: let your behaviour be that of children of light

9 (Because the fruit of the light is in all righteousness and in everything which is good and true),

10 Testing by experience what is well-pleasing to the Lord;

11 And have no company with the works of the dark, which give no fruit, but make their true quality clear;

12 For the things which are done by them in secret it is shame even to put into words.
