That which we have seen and heard declare we unto you, that ye may have fellowship with us, and that our fellowship may be with the father, and his son Jesus Christ.

but and if we walk in light even as he is in light, then have we fellowship together, and the blood of Jesus Christ his son cleanseth us from all sin.

My little children, these things write I unto you, that ye should sin not: if, though, any man sin, yet we have an Advocate with the father, even Jesus Christ, which is righteous.

Who is a liar, but he that denieth that Jesus is Christ? The same is the antichrist that denieth the father and the son.

And this is his commandment, that we believe on the name of his son Jesus Christ, and love one another, as he gave commandment.

Hereby shall ye know the spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh, is of God.

And every spirit that confesseth not that Jesus Christ is come in the flesh, is not of God. And the same is that spirit of antichrist, of whom ye have heard, how that he should come: and even now already is he in the world.

Whosoever confesseth that Jesus is the son of God, in him dwelleth God, and he in God.

All that believe that Jesus is Christ, are born of God. And all that loveth him which begat, loveth him also which was begotten of him.

Who is it that overcometh the world: but he which believeth that Jesus is the son of God?

This Jesus Christ is he that came by water and blood, not by water only: but by water and blood.

We know that the son of God is come, and hath given us understanding, to know him that is true: and we be in the truth through his son Jesus Christ. He is very God, and eternal life.
