Romans 3:3-5

3What then? If some did not believe, does their unbelief nullify the faithfulness of God?

4Absolutely not! Let God be proven true, and every human being shown up as a liar, just as it is written: “so that you will be justified in your words and will prevail when you are judged.”

5But if our unrighteousness demonstrates the righteousness of God, what shall we say? The God who inflicts wrath is not unrighteous, is he? (I am speaking in human terms.)
