Certainly not! God must be true, even though all human beings are liars. As the scripture says, "You must be shown to be right when you speak; you must win your case when you are being tried."
But what if our doing wrong serves to show up more clearly God's doing right? Can we say that God does wrong when he punishes us? (This would be the natural question to ask.)
Why not say, then, "Let us do evil so that good may come"? Some people, indeed, have insulted me by accusing me of saying this very thing! They will be condemned, as they should be.
Well then, are we Jews in any better condition than the Gentiles? Not at all! I have already shown that Jews and Gentiles alike are all under the power of sin.
Now we know that everything in the Law applies to those who live under the Law, in order to stop all human excuses and bring the whole world under God's judgment.
But now God's way of putting people right with himself has been revealed. It has nothing to do with law, even though the Law of Moses and the prophets gave their witness to it.
God offered him, so that by his blood he should become the means by which people's sins are forgiven through their faith in him. God did this in order to demonstrate that he is righteous. In the past he was patient and overlooked people's sins; but in the present time he deals with their sins, in order to demonstrate his righteousness. In this way God shows that he himself is righteous and that he puts right everyone who believes in Jesus.
