Romans 3:3-4

3What then? If some did not believe or were unfaithful [to God], their lack of belief will not nullify and make invalid the faithfulness of God and His word, will it?

4Certainly not! Let God be found true [as He will be], though every person be found a liar, just as it is written [in Scripture], “That You may be justified in Your words, And prevail when You are judged [by sinful men].”
