195. He who has received that Jesus is the Christ has certified that God is true.

Jn 3:32 And what he hath seen and heard, that he testifieth; and no man receiveth his testimony. 33 He that hath received his testimony hath set to his seal that God is true.

To deny that Jesus is the Christ is to make God a liar. (1 Jn 5:10)

1 Jn 5:10 He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
