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.
