Therefore those who are of faith are blessed with believing Abraham.

And Abram believed God, and it was accounted to him for righteousness.

For what does the Scripture say? "Abraham believed God, and it was accounted to him for righteousness."

But to him who does not work but believes on Him that justifies the ungodly, his faith is accounted for righteousness,

Why? Because [they did] not [seek it] by faith, but as it were, by the works of the law. For they stumbled the stone of stumbling.

Just as it is written: "Behold, I lay in Zion a stone of stumbling and rock of offense, and everyone believing on Him will not be put to shame."

And the Scripture was fulfilled which says, "Abraham believed God, and it was accounted to him for righteousness." And he was called a friend of God.

just as David also speaks of the blessing of the man to whom God accounts righteousness apart from works:

And he received the sign of circumcision, a seal of the righteousness of the faith which [he had while] in uncircumcision, so that he should be the father of all those that believe, although uncircumcised, so that righteousness should also be imputed to them,

And therefore "it was accounted to him for righteousness."

but for us also, to whom it was going to be imputed, those believing on Him who raised up Jesus our Lord from the dead,

that is, that God was in Christ reconciling the world to Himself, not reckoning their transgressions to them, and committing to us the word of this reconciliation.

For He made Him who knew no sin to be sin for us, so that we might become the righteousness of God in Him.
