1 John 5:10 - 5:12
10 The one who believes in the Son of God has this witness in himself. The one who does not believe God has made Him a liar, because he has not believed in the witness which God has borne witness about His Son. 11 And the witness is this, that God gave us eternal life, and this life is in His Son. 12 He who has the Son has the life; he who does not have the Son of God does not have that life.
