1 John 5:8-10

New Revised Standard Version Catholic Edition

⁸ the Spirit and the water and the blood, and these three agree. ⁹ If we receive human testimony, the testimony of God is greater; for this is the testimony of God that he has testified to his Son. ¹⁰ Those who believe in the Son of God have the testimony in their hearts. Those who do not believe in God^[a] have made him a liar by not believing in the testimony that God has given concerning his Son.
