Yesterday marked the beginning of Eid al-Adha, the Muslim festival commemorating Abraham's willingness to sacrifice his son. Muslims believe it was Ishmael who was nearly sacrificed. But Genesis 22 is clear that Isaac, the child of promise, was the one to be sacrificed. And he, the child of promise, was the one who Abraham received back from the dead.
The action took place on a mountain in the region of Moriah (Gen 22:2). Mount Moriah was where the temple would later be built (2 Chron 3:1). And so as they ascend this hill the father carries the tools of judgement - the fire and knife. The son carries the wood. He asks his father about the sacrifice. "God Himself will provide the lamb" says Abraham.
On this occasion the Angel of the LORD intercepts the judgement. (v11ff) He does so from heaven which is very odd for Him - usually He is more hands-on in His interactions. But one day He would come in Person to this mountain. And on that day He would intercept the judgement of the whole world. He would be the Child of promise, the Seed of Abraham and the Lamb of sacrifice. And on that day the Father would not spare His own Son but give Him up for us all. (Rom 8:32).
In Genesis 22, a ram is provided as a substitute for Isaac (v13). But of course, Abraham had prophesied that a lamb would be provided (v8). And this prophecy was believed and proclaimed throughout the generations:
Abraham called that place "The LORD Will Provide". And to this day it is said, "On the mountain of the LORD it will be provided."
The true substitutionary sacrifice, the true promised Son, the true Seed of Abraham would die as a Lamb on that mountain in the region of Jerusalem.
Islam celebrates father Abraham, Ishmael and the sacrifice that saved him. But this is not the true Eid - the true sacrifice. All of this points to the true Father who did not spare His Son. To the true Child of Promise who was willing to lay down His life and to the true Sacrifice that was provided for all.
