For what says the scripture? Abraham believed God, and it was counted unto him for righteousness.

AD 397
I do not demand a reason from Christ. If I am convinced by reason, I deny faith. Abraham believed God. Let us also believe, so that we who are the heirs of his race may likewise be heirs of his faith.
Paul revealed that Abraham had glory before God not because he was circumcised nor because he abstained from evil, but because he believed in God. For that reason he was justified, and he would receive the reward of praise in the future. Commentary on Paul’s Epistles.
But if he was not, how did he straightway believe, as it were naturally? And if he was elect, their hypothesis is done away with, in as much as even previous to the coming of the Lord an election was found, and that saved: "For it was reckoned to him for righteousness.".
And on learning the way of truth, let us walk on the right way, without turning till we attain to what we desire: It was therefore with reason that the king of the Romans (his name was Numa), being a Pythagorean, first of all men, erected a temple to Faith and Peace. "And to Abraham, on believing, righteousness was reckoned."
For what saith the Scripture? Abraham believed God, and it was reputed to him unto justice. The Scripture, therefore, teacheth us that he became just by his faith. And as he had this faith by the grace of God, grace was the cause of his justification, and not any works without grace. And when it is said, it was reputed to him, we must not understand an imputation of being just without a true and interior justice: for to be reputed just in the sight of God, who sees the heart, and sanctifies the soul by his interior grace, is the only true justice that can make a man acceptable to God. As not to have our sins imputed in the sight of God, is to have them forgiven, and to be free from our sins. (Witham)
Reputed By God, who reputeth nothing otherwise than it is. However, we may gather from this word, that when we are justified, our justification proceedeth from God's free grace and bounty; and not from any efficacy which any act of ours could have of its own nature, abstracting from God's...
Abraham believed that God was the maker of heaven and earth, the only true God, and he also believed that God would make his seed as numerous as the stars of heaven. .
The Master proclaimed that Abraham was just because he outran the weakness of his human nature. He strained with his whole mind toward the power of him who had made the promise.
Accordingly it is patience which is both subsequent and antecedent to faith. In short, Abraham believed God, and was accredited by Him with righteousness;
