I John 1:6-2:6
"If we say that we have
fellowship with him, and walk in darkness, we lie, and do not the truth: But if
we walk in the light, as he is in the light, we have fellowship one with
another, and the blood of Jesus Christ his Son cleanseth us from all sin. If we
say that we have no sin, we deceive ourselves, and the truth is not in us. If we
confess our sins, he is faithful and just to forgive us our sins, and to cleanse
us from all unrighteousness. If we say that we have not sinned, we make him a
liar, and his word is not in us. My little children, these things write I unto
you, that ye sin not. And if any man sin, we have an advocate with the Father,
Jesus Christ the righteous: And he is the propitiation for our sins: and not for
ours only, but also for the sins of the whole world. And hereby we do know that
we know him, if we keep his commandments. He that saith, I know him, and keepeth
not his commandments, is a liar, and the truth is not in him. But whoso keepeth
his word, in him verily is the love of God perfected: hereby know we that we are
in him. He that saith he abideth in him ought himself also so to walk, even as
he walked."
