1JN 5:10

10 He that believeth in the Son of God, hath the witnessing of God in him. He that believeth not to the Son, maketh him a liar; for he believeth not in the witnessing that God witnessed of his Son. (He who believeth in the Son of God, hath God’s testimony in him. He who believeth not in the Son, maketh him out to be a liar; for he believeth not in the testimony that God testified about his Son.)
