10
He who believes in the Son of God has the witness in him. He who doesn`t believe God has made him a liar, because he has not believed in the testimony that God has given concerning his Son.
11
The testimony is this, that God gave to us eternal life, and this life is in his Son.
12
He who has the Son has the life. He who doesn`t have God`s Son doesn`t have the life.
