1 John 1-2:5
1We declare to you what was from the beginning, what we have heard, what we have seen with our eyes, what we have looked at and touched with our hands, concerning the word of life— 2this life was revealed, and we have seen it and testify to it, and declare to you the eternal life that was with the Father and was revealed to us— 3we declare to you what we have seen and heard so that you also may have fellowship with us; and truly our fellowship is with the Father and with his Son Jesus Christ. 4We are writing these things so that our joy may be complete.
5This is the message we have heard from him and proclaim to you, that God is light and in him there is no darkness at all. 6If we say that we have fellowship with him while we are walking in darkness, we lie and do not do what is true; 7but 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.
8If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9If we confess our sins, he who is faithful and just will forgive us our sins and cleanse us from all unrighteousness. 10If we say that we have not sinned, we make him a liar, and his word is not in us.
2My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous; 2and he is the atoning sacrifice for our sins, and not for ours only but also for the sins of the whole world.
3Now by this we may be sure that we know him, if we obey his commandments. 4Whoever says, “I have come to know him,” but does not obey his commandments, is a liar, and in such a person the truth does not exist; 5but whoever obeys his word, truly in this person the love of God has reached perfection. By this we may be sure that we are in him.
