1 John 5:10-11

New King James Version

¹⁰ He who believes in the Son of God ^(A)has the witness in himself; he who does not believe God ^(B)has made Him a liar, because he has not believed the testimony that God has given of His Son. ¹¹ And this is the testimony: that God has given us eternal life, and this life is in His Son.
