1 John 5:8 (KJV)

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

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

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 water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.

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

He that hath the Son hath life; and he that hath not the Son of God hath not life.

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.
