3 Bible Verses about Making God A Liar

The one who believes in the Son of God [who adheres to, trusts in, and relies confidently on Him as Savior] has the testimony within himself [because he can speak authoritatively about Christ from his own personal experience]. The one who does not believe God [in this way] has made Him [out to be] a liar, because he has not believed in the evidence that God has given regarding His Son.

If we say that we have not sinned [refusing to admit acts of sin], we make Him [out to be] a liar [by contradicting Him] and His word is not in us.

“How can you say, ‘We are wise,
And the law of the Lord is with us [and we are learned in its language and teachings]’?
Behold, [the truth is that] the lying pen of the scribes
Has made the law into a lie [a mere code of ceremonial observances].
