1 John 5:9-12
5:9 If we accept the testimony of men, the testimony of God is greater, because this is the testimony of God that he has testified concerning his Son.
5:10 (The one who believes in the Son of God has the testimony in himself; the one who does not believe God has made him a liar, because he has not believed in the testimony that God has testified concerning his Son.)
5:11 And this is the testimony: God has given us eternal life, and this life is in his Son.
5:12 The one who has the Son has this eternal life; the one who does not have the Son of God does not have this eternal life.
