10. Whoever believes in the Son of God has this testimony within himself. Whoever does not believe God has made him a liar by not believing the testimony God has given about his Son.
11. And this is the testimony: God gave us eternal life, and this life is in his Son.
12. Whoever possesses the Son has life; whoever does not possess the Son of God does not have life.
13. I write these things to you so that you may know that you have eternal life, you who believe in the name of the Son of God.
