5 This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. 6 If we claim to have fellowship with him yet walk in the darkness, we lie and do not live by 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, purifies us from all sin.
8 If we claim to be without sin, we deceive ourselves and the truth is not in us. 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word has no place in our lives.
It is important to note that the apostle John makes it clear that this message is not his but Christ’s. And what is this message? God is light and we are to walk in this light. “Light” and “love” and “life” are key words in this short epistle. I took a highlighter to my Bible to emphasize these important concepts. Re-read verse 7 and consider the awesome promise there. Then do what it says in verse 9 — you don’t need to confess to a priest or anyone else, just confess to God and he will forgive you. It's pretty awesome to know you can be purified from all unrighteousness.
