1 John 5:12 (KJV)

For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.

And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.

If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.

He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.

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

These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.

And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:

And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.

If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.

All unrighteousness is sin: and there is a sin not unto death.
