5 This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all.6 If we say we have fellowship with him while we walk in darkness, we lie and do not practice the truth.7 But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin.
Ephesians 5
8 for at one time you were darkness, but now you are light in the Lord. Walk as children of light9 (for the fruit of light is found in all that is good and right and true),10 and try to discern what is pleasing to the Lord.11 Take no part in the unfruitful works of darkness, but instead expose them.
