1 John 1
The Word of Life
1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and have touched with our hands, concerning the word of life -
2 the life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life, which was with the Father and was made manifest to us -
3 that which we have seen and heard we proclaim also to you, so that you too may have fellowship with us; and indeed our fellowship is with the Father and with his Son Jesus Christ.
4 And we are writing these things so that our joy may be complete.
Heard, seen and touched - the Apostle emphasizes the fact that he was an eye witness to the person of Jesus - both before and after the resurrection.
Walking in the light
5 This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all.
People who love to quote "God is love" (1John 4:8), another of John's sayings, often overlook the fact that he also said "God is light".
6 If we say we have fellowship with him while we walk in darkness, we lie and don't practice 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, cleanses us from all sin.
8 If we say we have no sin, we deceive ourselves, and the truth isn't in us.
Anyone who says he has no sin is lying to himself and doesn't have the truth in him.
9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
10 If we say we haven't sinned, we make him a liar, and his word isn't in us.
Anyone who say he isn't a sinner contradicts Jesus himself and is calling him a liar.
