Romans 3:3-5

3So what if some did not trust? Will their lack of faith nullify God’s faithfulness?

4May it never be! Let God be true even if every man is a liar, as it is written, “that You may be righteous in Your words and prevail when You are judged.”

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