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.)
11. And this is the testimony: that God has given us eternal life, and this life is in his Son.
12. The one who has the Son has the life; the one who does not have the Son of God does not have the life.
13. These things I have written to you who believe in the name of the Son of God, in order that you may know that you have eternal life.
