The first great lesson which the interposition of the Divine voice teaches us, is that obedience is complete when the inward surrender is complete. The outward act was needless. Abraham would have done no more if the flashing knife had buried itself in Isaac's heart. Here is the first great proclamation of the truth which revolutionizes morality and religion, the beginnings of the teaching which culminates in the ethics of the Sermon on the Mount, and in the gospel of salvation, not by deeds, but through faith. The will is the man, the true action is the submission of the will. The outward deed is only the coarse medium through which it is made visible for men: God looks on purpose as performance.
Again, faith is rewarded by God's acceptance and approval. I know that thou fearest God,' not meaning that He learned the heart by the conduct, but that, on occasion of the conduct, He breathes into the obedient heart that calm consciousness of its service as recognized and accepted by Him, which is the highest reward that His friend can know. To be well pleasing to Him' is our noblest aim, which, cherished, makes sacrifice sweet, and all difficult things easy. Nor know we anything more fair Than is the smile upon Thy face.'
Again, faith is rewarded by a deeper insight into God's will. Much has been said about the sacrifice of Isaac in its bearing upon the custom of human sacrifice. We do not believe that Abraham was led to his act by a mistaken idea, borrowed from surrounding idolatries. His position as the sole monotheist amid these, the absence of evidence that human sacrifice was practiced then among his neighbors, and, above all, the fact of the divine approval of his intention, forbid our acceptance of that theory. Nor can we regard the condemnation of such sacrifices as the main object of the incident. But no doubt an incidental result, and, we may perhaps say, a subsidiary purpose of it, was to stamp all such hideous usage's with the brand of God's displeasure. The mode of thought which led to them was deeply rooted in the consciousness of the Old World, and corresponded to a true conception of the needs of humanity. The dark sense of sin, the conviction that it required expiation, and that procurable only by death, drove men to these horrid rites. And that ram, caught in the thicket, thorn-crowned and substituted for the human victim, taught Abraham and his sons that God appointed and provided a lamb for an offering. It was a lesson won by faith. Nor need we hesitate to see some dim forecast of the great Substitute whom God provided, who bears the sins of the world.
Again, faith is rewarded by receiving back the surrendered blessing, made more precious because it has been laid on the altar. How strange and solemn must have been the joy with which these two looked in each other's faces! What thankful wonder must have filled Abraham's heart as he loosed the cord that had bound his son! It would be many days before the thrill of gratitude died away, and the possession of his son seemed to Abraham, or that of life seemed to Isaac, a common thing. He was doubly now a child of wonder, born by miracle, delivered by miracle. So is it ever. God gives us back our sacrifices, tinged with a new beauty, and purified from earthly alloy. We never know how sweet our blessings are till we have yielded them to Him. There is no man that hath left' anything or any person for Christ's sake and the gospel's who will not' receive a hundred-fold more in this life, and in the world to come life everlasting.'
Lastly, Abraham was rewarded by being made a faint adumbration, for all time, of the yet more wondrous and awful love of the divine Father, who, for our sakes, has surrendered His only-begotten Son, whom He loved. Paul quotes the very words of this chapter when he says: He that spared not His own Son, but delivered Him up for us all.' Such thoughts carry us into dim regions, in which, perhaps, silence is best. Did some shadow of loss and pain pass over the divine all-sufficiency and joy, when He sent His Son? Was the unresisting innocence of the son a far-off likeness of the willing eagerness of the sinless Sufferer who chose to die? Was the resolved surrender of the father a faint prelude of the deep divine love which gave His only Son for us? Shall we not say, Now I know that Thou lovest me, because Thou hast not withheld Thy Son, Thine only Son, from me'? Shall we not recognize this as the crown of Abraham's reward, that his act of surrender of his dearest to God, his Friend, has been glorified by being made the mirror of God's unspeakable gift of His Son to us, His enemies?
