'Righteousness' in the Bible

I do not misapply God's grace, for if righteousness comes about by doing what the Law requires, then the Messiah died for nothing.

In the same way, Abraham "believed God, and it was credited to him as righteousness."

So is the Law in conflict with the promises of God? Of course not! For if a law had been given that could give us life, then certainly righteousness would come through the Law.
