Romans 3:4-6

RKJNT(i) 4 God forbid: let God be true, even if every man is a liar; as it is written, That you might be justified in your words, and might overcome when you are judged. 5 But if our unrighteousness demonstrates the righteousness of God, what shall we say? That God is unrighteous who takes vengeance? (I speak as a man) 6 God forbid: for then how shall God judge the world?
