1 John 1:5-7

5 This is the word which came to us from him and which we give to you, that God is light and in him there is nothing dark.

6 If we say we are joined to him, and are walking still in the dark, our words are false and our acts are untrue:

7 But if we are walking in the light, as he is in the light, we are all united with one another, and the blood of Jesus his Son makes us clean from all sin.
