Genesis 22:2

2. Take now thy son. Abraham is commanded to immolate his son. If God had said nothing more than that his son should die, even this message would have most grievously wounded his mind; because, whatever favor he could hope for from God, was included in this single promise, In Isaac shall thy seed be called. Whence he necessarily inferred, that his own salvation, and that of the whole human race, would perish, unless Isaac remained in safety. For he was taught, by that word, that God would not be propitious to man without a Mediator. For although the declaration of Paul, that ‘all the promises of God in Christ are yea and Amen,’ was not yet written, (2 Corinthians 1:20,) it was nevertheless engraven on the heart of Abraham. Whence, however, could he have had this hope, but from Isaac? The matter had come to this; that God would appear to have done nothing but mock him. Yet not only is the death of his son announced to him, but he is commanded with his own hand to slay him, as if he were required, not only to throw aside, but to cut in pieces, or cast into the fire, the charter of his salvation, and to have nothing left for himself, but death and hell. But it may be asked, how, under the guidance of faith, he could be brought to sacrifice his son, seeing that what was proposed to him, was in opposition to that word of God, on which it is necessary for faith to rely? To this question the Apostle answers, that his confidence in the word of God remained unshaken; because he hoped that God would be able to cause the promised benediction to spring up, even out of the dead ashes of his son. (Hebrews 11:19.) His mind, however, must of necessity have been severely crushed, and violently agitated, when the command and the promise of God were conflicting within him. But when he had come to the conclusion, that the God with whom he knew he had to do, could not be his adversary; although he did not immediately discover how the contradiction might be removed, he nevertheless, by hope, reconciled the command with the promise; because, being indubitably persuaded that God was faithful, he left the unknown issue to Divine Providence. Meanwhile, as with closed eyes, he goes whither he is directed. The truth of God deserves this honor; not only that it should far transcend all human means, or that it alone, even without means, should suffice us, but also that it should surmount all obstacles. Here, then, we perceive, more clearly, the nature of the temptation which Moses has pointed out. It was difficult and painful to Abraham to forget that he was a father and a husband; to cast off all human affections; and to endure, before the world, the disgrace of shameful cruelty, by becoming the executioner of his son. But the other was a far more severe and horrible thing; namely, that he conceives God to contradict Himself and His own word; and then, that he supposes the hope of the promised blessing to be cut off from him, when Isaac is torn away from his embrace. For what more could he have to do with God, when the only pledge of grace is taken away? But as before, when he expected seed from his own dead body, he, by hope, rose above what it seemed possible to hope for; so now, when, in the death of his son, he apprehends the quickening power of God, in such a manner, as to promise himself a blessing out of the ashes of his son, he emerges from the labyrinth of temptation; for, in order that he might obey God, it was necessary that he should tenaciously hold the promise, which, had it failed, faith must have perished. But with him the promise always flourished; because he both firmly retained the love with which God had once embraced him, and subjected to the power of God everything which Satan raised up to disturb his mind. But he was unwilling to measure, by his own understanding, the method of fulfilling the promise, which he knew depended on the incomprehensible power of God. It remains for every one of us to apply this example to himself. The Lord, indeed, is so indulgent to our infirmity, that he does not thus severely and sharply try our faith: yet he intended, in the father of all the faithful, to propose an example by which he might call us to a general trial of faith. For the faith, which is more precious than gold and silver, ought not to lie idle, without trial; and experience teaches, that each will be tried by God, according to the measure of his faith. At the same time, also, we may observe, that God tempts his servants, not only when he subdues the affections of the flesh, but when he reduces all their senses to nothing, that he may lead them to a complete renunciation of themselves.

Thine only son Isaac, whom thou lovest. As if it were not enough to command in one word the sacrifice of his son, he pierces, as with fresh strokes, the mind of the holy man. By calling him his only son, he again irritates the wound recently indicted, by the banishment of the other son; he then looks forward into futurity, because no hope of offspring would remain. If the death of a firstborn son is wont to be grievous, what must the mourning of Abraham be? Each word which follows is emphatical, and serves to aggravate his grief. ‘Slay’ (he says) ‘him whom alone thou lowest.’ And he does not here refer merely to his paternal love, but to that which sprung from faith. Abraham loved his son, not only as nature dictates, and as parents commonly do, who take delight in their children, but as beholding the paternal love of God in him: lastly, Isaac was the mirror of eternal life, and the pledge of all good things. Wherefore God seems not so much to assail the paternal love of Abraham, as to trample upon His own benevolence. There is equal emphasis in the name Isaac by which Abraham was taught, that nowhere besides did any joy remain for him. Certainly, when he who had been given as the occasion of joy, was taken away, it was just as if God should condemn Abraham to eternal torment. We must always remember that Isaac was not a son of the common order, but one in whose person the Mediator was promised.
