1John:5:10-11
nkjv@1John:5:10 @ He who believes in the Son of God has the witness in himself; he who does not believe God has made Him a liar, because he has not believed the testimony that God has given of His Son.
nkjv@1John:5:11 @ And this is the testimony: that God has given us eternal life, and this life is in His Son.
