Faith Righteousness

In our series on the Book of Romans we covered chapter four. We learned that the faith righteousness, displayed through Abraham, is the faith of the believer. It is by grace we are saved, through faith. What does righteousness mean? Are we righteous now or when we get to heaven? 

"(Abraham), fully persuaded that God had power to do what he had promised. This is why, 'it was credited to him as righteousness.'" (Romans 4:21-22)
