5 This is the message we have heard from him and declare to you: God is light,  * and there is absolutely no darkness in him.  *6 If we say, "We have fellowship  * with him," and yet we walk in darkness,  * we are lying and are not practicing the truth.  *7 If we walk in the light  * as he himself is in the light, we have fellowship with one another, and the blood of Jesus  * his Son cleanses us from all sin.
