That which we have seen and heard declare we to you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son, Jesus Christ:

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.

My beloved children, I write these things to you, that ye may not sin. But if any one sin, we have an advocate with the Father, Jesus Christ, the righteous, And he is the propitiation for our sins;

Who is that liar, but he that denieth that Jesus is the Christ? He is Antichrist who denieth the Father and the Son.

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

Hereby ye know the spirit of God: every spirit which confesseth Jesus Christ come in the flesh, is of God.

And every spirit which confesseth not Jesus Christ come in the flesh, is not of God: and this is that spirit of Antichrist, whereof ye have heard that it should come; and now already it is in the world.

Whosoever shall confess, that Jesus is the Son of God, God abideth in him, and he in God.

Whosoever believeth that Jesus is the Christ is born of God; and every one who loveth him that begat, loveth him also that is begotten of him.

Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?

This is he that came by water and blood; even Jesus Christ; not by the water only, but by the water and the blood: and it is the Spirit who testifieth; because the Spirit is truth.

But we know that the Son of God is come; and he hath given us an understanding that we may know the true one; and we are in the true one, even in his Son Jesus Christ; this is the true God and eternal life.
