Genesis 15:6

And he believed in the Lord; and he counted it to him for righteousness - This I conceive to be one of the most important passages in the whole Old Testament. It properly contains and specifies that doctrine of justification by faith which engrosses so considerable a share of the epistles of St. Paul, and at the foundation of which is the atonement made by the Son of God: And he (Abram) believed האמן heemin, he put faith) in Jehovah, ויחשבה לו vaiyachshebeita lo, and he counted it - the faith he put in Jehovah, to Him for righteousness, צדקה tsedakah, or justification; though there was no act in the case but that of the mind and heart, no work of any kind. Hence the doctrine of justification by faith, without any merit of works; for in this case there could be none - no works of Abram which could merit the salvation of the whole human race. It was the promise of God which he credited, and in the blessedness of which he became a partaker through faith. See at Genesis 15:19 (note); see also on Romans 4 (note).

And Abram believed in the Lord. - Thus, at length, after many throes of labor, has come to the birth in the breast of Abram "faith in Yahweh," on his simple promise in the absence of all present performance, and in the face of all sensible hinderance. The command to go to the land which the Lord would show him, accompanied with the promise to make of him a great nation, had awakened in him a certain expectation; which, however, waited for some performance to ripen it into faith. But waiting in a state of suspense is not faith, but doubt; and faith after performance is not faith, but sight. The second and third renewal of the promise, while performance was still unseen in the distance, was calculated to slay the expectancy that still paused for realization, to give it the vitality of a settled consent and acquiescence in the faithfulness of God, and mature it into conviction and confession.

What was there now, then, to call forth Abram's faith more than at the first promise? There was the reiteration of the promise. There was the withholding of the performance, leaving room for the exercise of pure faith. There was time to train the mind to this unaccustomed idea and determination. And, lastly, there was the sublime assurance conveyed in the sentence, "I am thy shield, thy exceeding great reward," transcending all the limits of time and place, comprehending alike the present and the eternal, the earthly and the heavenly. This, coupled with all the recorded and unrecorded dealings of the Lord, leads him to conceive the nobler feeling of faith in the Promiser, antecedent to any part of the execution, any unfolding of the plan, or any removal of the obvious difficulty. The moment of deliverance draws nigh, when Abram at length ventures to open his mouth and lay bare, in articulate utterance, the utmost questionings of his soul before the Lord. And then, in due time is effected the birth of faith; not by commencing the accomplishment of the promise, but by the explicit reassertion of its several parts, in the light of that grand assurance which covers it in its narrowest and in its most expanded forms. Thus, faith springs solely from the seed of promise. And from that moment there stands up and grows within the breast of man the right frame of mind toward the God of mercy - the germ of a mutual good understanding between God and man which will spread its roots and branches through the whole soul, to the exclusion of every noxious plant, and blossom forth unto the blessed fruit of all holy feelings and doings.

And he counted it to him for righteousness. - First. From this confessedly weighty sentence we learn, implicitly, that Abram had no righteousness. And if he had not, no man had. We have seen enough of Abram to know this on other grounds. And here the universal fact of man's depravity comes out into incidental notice, as a thing usually taken for granted, in the words of God. Second. Righteousness is here imputed to Abram. Hence, mercy and grace are extended to him; mercy taking effect in the pardon of his sin, and grace in bestowing the rewards of righteousness. Third. That in him which is counted for righteousness is faith in Yahweh promising mercy. In the absence of righteousness, this is the only thing in the sinner that can be counted for righteousness. First, it is not of the nature of righteousness. If it were actual righteousness, it could not be counted as such. But believing God, who promises blessing to the undeserving, is essentially different from obeying God, who guarantees blessing to the deserving. Hence, it has a negative fitness to be counted for what it is not. Secondly, it is trust in him who engages to bless in a holy and lawful way. Hence, it is that in the sinner which brings him into conformity with the law through another who undertakes to satisfy its demands and secure its rewards for him. Thus, it is the only thing in the sinner which, while it is not righteousness, has yet a claim to be counted for such, because it brings him into union with one who is just and having salvation.

It is not material what the Almighty and All-gracious promises in the first instance to him that believes in him, whether it be a land, or a seed, or any other blessing. All other blessing, temporal or eternal, will flow out of that express one, in a perpetual course of development, as the believer advances in experience, in compass of intellect, and capacity of enjoyment. Hence, it is that a land involves a better land, a seed a nobler seed, a temporal an eternal good. The patriarchs were children to us in the comprehension of the love of God: we are children to those who will hereafter experience still grander manifestations of what God has prepared for them that love him. The shield and exceeding great reward await a yet inconceivable enlargement of meaning.

15:6 And he believed in the Lord - That is, believed the truth of that promise which God had now made him, resting upon the power, and faithfulness of him that made it: see how the apostle magnifies this faith of Abram, and makes it a standing example, Rom 4:19 - 21. He was not weak in faith; he staggered not at the promise: he was strong in faith; he was fully persuaded. The Lord work such a faith in every one of us. And he counted it to him for righteousness - That is, upon the score of this he was accepted of God, and, by faith he obtained witness that he was righteous, Heb 11:4. This is urged in the New Testament to prove, that we are justified by faith without the works of the law, Rom 4:3,Gal 3:6, for Abram was so justified, while he was yet uncircumcised. If Abram, that was so rich in good works, was not justified by them, but by his faith, much less can we. This faith, which was imputed to Abram for righteousness, had newly struggled with unbelief, Ge 15:2, and coming off, conqueror, it was thus crowned, thus honoured.
