Yea there are three that bear witness, the Spirit, and the water, and the blood:

These things have I written to you, who believe on the name of the son of God, that ye may know that ye have eternal life, and that ye may the more firmly believe on the name of the Son of God.

And the testimony is this, that God hath given to us eternal life; and this life is in his Son.

And this is the confidence, which we have towards Him, that if we ask any thing according to his will, He heareth us:

Whosoever believeth that Jesus is the Christ is born of God: and every one, that loveth Him that begat, loveth Him also that is begotten of Him:

and these three agree in one.

For whatsoever is born of God overcometh the world: and this is the victory that vanquisheth the world, even our faith.

For this is the love of God, that we keep his commandments: and his commandments are not grievous.

We know that we are of God, and the whole world lieth under the wicked one.

But we know that the son of God is come, and hath given us understanding, that we may know Him that is true, and we are in Him that is true, and in his son Jesus Christ: He is the true God, and eternal life.

He that hath the Son hath life: he that hath not the Son of God hath not life.

If any one see his brother commit a sin which is not unto death, let him pray for him, and God will give him life, that is for them that do not sin unto death. There is a sin unto death: and for that I do not say that he should pray.

We know that whosoever is born of God, doth not practise sin: but keepeth himself from it, and the wicked one doth not touch him.

and if we know that He heareth us in whatsoever we ask; we know that we shall have the petitions, which we have requested of Him.

All unrighteousness indeed is sin, and yet there is a sin not unto death.

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

He, that believeth on the Son of God, hath the witness in himself: he, that believeth not God, hath in effect made Him a liar, because he believed not the testimony which God hath testified of his Son.

Little children, keep yourselves from idols. Amen.

This is He that came by water and by blood, even Jesus the Messiah; not with water only, but with water and blood: and of this the Spirit beareth witness, for the Spirit is truth.

Now if we admit the testimony of men, sure the testimony of God is greater: and this is the testimony of God, which He hath testified concerning his Son.

and in this we know that we love the children of God, since we love God and keep his commandments.
