1 John 5:10-12

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.
