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