This is the message we heard from Jesus and now declare to you: God is light and there is no darkness inHim at all. So we are lying if we say we have fellowship with God but go on living in spiritual darkness; we are not practicing the truth. But if are living in the light, as God is in the light, then we have fellowship with each other, and the blood of Jesus, His Son, cleanses us from all sin.
If we claim we have no sin, we are only fooling ourselves and not loving in the truth. But if we confess our sins to Him, Hew is faithful and just to forgive us our sins and to cleanse us from all wickedness. If we claim we have not sinned, we are calling God a liar and showing that His words has no place in our hearts. (vv.5-10, NLT)
