3 Bible Verses about Making God A Liar

He who is believing in the Son of God, hath the testimony in himself; he who is not believing God, a liar hath made Him, because he hath not believed in the testimony that God hath testified concerning His Son;

if we may say -- 'we have not sinned,' a liar we make Him, and His word is not in us.

How do ye say, We are wise, And the law of Jehovah is with us? Surely, lo, falsely it hath wrought, The false pen of scribes.
