1 John 5:9-11

Revised Standard Version Catholic Edition

⁹ If we receive the testimony of men, the testimony of God is greater; for this is the testimony of God that he has borne witness to his Son. ¹⁰ He who believes in the Son of God has the testimony in himself. He who does not believe God has made him a liar, because he has not believed in the testimony that God has borne to his Son. ¹¹ And this is the testimony, that God gave us eternal life, and this life is in his Son.
