1 John 5:10-11 He who believes in the Son of God has the testimony in his own heart: he who does not believe God has made Him a liar, in that he has refused to accept the testimony which God has given about His Son.

WNT⁽ⁱ⁾ ¹⁰ He who believes in the Son of God has the testimony in his own heart: he who does not believe God has made Him a liar, in that he has refused to accept the testimony which God has given about His Son. ¹¹ And that testimony is to the effect that God has given us the Life of the Ages, and that this Life is in His Son.
