Today, we wrap up our study of the sacrifice of Isaac. Over the past three weeks we've looked at it from Abraham's point of view and now God's point of view. Having passed the test, Abraham now stands approved. And, now, God gives Abraham the final evaluation and the final word of revelation for his long life.

Abraham has believed, obeyed, and seen Christ’s day. Over the course of these many years since his first calling, he has been pulled from a pagan culture, shaped and re-identified as the father of a new people, a unique people of God’s own choosing. He has slipped into the manner of the old way time and again, but by God’s gracious intervention he has had his thinking and actions corrected and reformed. The land has been declared his and his seed’s by promise. Abraham has believed in his heart and acted with his hand the faith that God has declared righteous. Now, the Lord speaks to him for the last time in a sort of capstone declaration that matches closely the initial call that began Abraham’s journey:
By myself I have sworn, declares the LORD, because you have done this and have not withheld your son, your only son, I will surely bless you, and I will surely multiply your offspring as the stars of heaven and as the sand that is on the seashore. And your offspring shall possess the gate of his enemies and in your offspring shall all the nations of the earth be blessed, because you have obeyed my voice. (Genesis 22:16-18)
This brief word resonates with reminders of the highlights of the relationship that has developed between Abraham and the LORD. When God says, “By myself I have sworn,” it hearkens to the covenant cutting ceremony back in Genesis 15 when God passed through the slain carcasses alone. In that formal ceremony God’s actions declared that the covenant’s fulfillment is certain, else his very character and nature are for naught. Now, he re-confirms that action with a further word of explanation.
Though Abraham did not pass through the pieces, he has taken the covenantal obligations seriously. He bears the mark of covenant in his very flesh, as do the males of his household and his sons. As God declares here, Abraham has not withheld his son: he circumcised the boy, marking him as one of his own and thus one of God’s own. The mark has not proven to be vain for Abraham stands on the mount, knife in hand, ready to offer Isaac unto the God whose mark they both bear. This is an act of monumental faith! He’s been told, “through Isaac shall your offspring be named” (Genesis 21:12). Fairburn comments, “According to this word, God’s purpose to bless was destined to have its accomplishment especially and peculiarly through Isaac; so that to slay such a son appeared like slaying the very word of God, and extinguishing the hope of the world."[1] To slay Isaac the child of promise is to slay the promises that God had given Abraham in the beginning. Without Isaac Abraham will not be a great nation. Without Isaac his name will not be great but a byword. Without Isaac the nations will not be blessed. The hope of what Paul calls the “gospel beforehand to Abraham” will be snuffed out when Isaac’s breath abates and his blood spills on the altar. Abraham is ordered to destroy all that he has hoped for, longed for, suffered for. He has believed in the surety of the promises of God but if God wants to cut off their possible fulfillment, Abraham will obey.
Abraham’s faith has been justly evaluated and proven true and now God reiterates the very promises that had been so desperately threatened. God will “surely” bless him and “surely” multiply him. These promises are certain and, what’s more, they are on a worldwide scale. God extends and compounds two of the metaphors that he had used before—dust and stars. As God had told Abraham when the covenant had been cut (Genesis 15:5), he tells him again: his offspring shall be “as the stars of heaven.” Prior to this God had said they would be “as the dust of the earth” (Genesis 13:16); now he says they shall be “as the sand that is on the seashore.” Wherever Abraham goes, that which is most numerous at his head and that which is most numerous at his feet shall picture for him the fullness of his descendants.
God then adds something to the promises that has not been spoken before. Abraham’s offspring shall “possess the gate of his enemies.” This is an image of sure possession of the land. Abraham has been informed that for now and for a few generations to come, he and his offspring are but sojourners in the land. Ah, but someday, they shall possess the land. Someday, their enemies shall not prevail against them. This is God’s reassertion that Abraham’s enemies shall be his enemies. It is, for we the reader, a prophetic image of the coming day of the Exodus and the conquest of the land of promise. Beyond that, it is a picture of the coming dominion of Christ, as the strong man is bound, as every thought is brought into obedience to him, as every knee bows and every tongue confesses that he is Lord.
Finally, God repeats the promise that is the gospel beforehand, the promise that is the one hope for all the world: “in your offspring shall all the nations of the earth be blessed.” Abraham has not withheld Isaac from God and so God proclaims that he will not withhold his blessing to all the earth. God will make good the word and the action that he has bound himself to. God is satisfied in his judgment and satisfies any anxiety or uncertainty that may have crept into Abraham’s soul. The Patriarch turns and heads down the mountain to his servant men, just as he had told them he would. And, the test complete and passed, the band returns to Beersheeba together.
