Would you Please Explain Romans 4:15 and 5:13?
Paul does not say there was no law in the day of Abraham or even before that. That is not his point at all. He merely says that where there is no law then there is no transgression. What then is the point? His point is that when God gave the promise to Abraham, that promise was given without law. Hence that promise was made to Abraham upon the condition of faith, not upon the condition of law.
