3 Bible Verses about Making God A Liar

(The one who believes in the Son of God has the testimony in himself. The one who does not believe God has made him a liar, because he has not believed in the testimony that God has testified concerning his Son.)

If we say that we have not sinned, we make him a liar, and his word is not in us.

How can you say, 'We [are] wise and the law of Yahweh [is] with us'? Look, surely {the lying stylus of the scribes} has made it a lie.
