1 John 5:9-13 Revised Standard Version (RSV)
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. 12 He who has the Son has life; he who has not the Son of God has not life.
13 I write this to you who believe in the name of the Son of God, that you may know that you have eternal life.
