Critics tend to read into the Bible what they want, irrespective of both tradition and scholarship. And this is a subject that has been brought up repeatedly with the same typical conclusions: God is a horrible entity that clearly is bloodthirsty, unreasonable with a propensity to murder the innocent.
Little will come of it here except to get it out of your system. You ignore everything (ancient and modern) that’s been written on it and your mind is made up.
Sacrifice is (and was during the time of Abraham) a tradition that pointed the way to Christ’s atoning sacrifice. The sacrifice of an animal would have no meaning to an all-powerful deity unless it was a teaching device to benefit the children of men. The animals sacrificed had to be perfect, without blemish, to represent the perfect nature of the Son of God. And God commanded Abraham to sacrifice his only begotten son as a way of pointing to the time when Christ would be offered up as a sacrifice for sin.
“God too acted strangely!” you conclude. “No introduction of the subject with sufficient reasons.” But how do you know this? We only have what was passed down. In other accounts, Abraham reasons that God would either prevent him from sacrificing his son or that He would resurrect Isaac in the event he had to go through with it. Abraham knew that human sacrifice had been condemned by God, so he had good reason to conclude this. Either way, the agony suffered by Abraham was what Abraham had to wrestle with, and it teaches us that the Atonement of Christ also was a huge matter with the Father, and one in which the Father suffered greatly.
In one ancient document, we have this exchange between
the Father and the Messiah:
And He (the Father) heaved sighs over him, saying, ‘If I put breath into this [man], he must suffer many pains.’ And I said unto My Father, ‘Put breath into him; I will be an advocate for him.’ And My Father said unto Me, ‘If I put breath into him, My beloved Son, Thou wilt be obliged to go down into the world, and to suffer many pains for him before Thou shalt have redeemed him, and made him to come back to his primal state.’ And I said unto My Father, ‘Put breath into him; I will be his advocate, and I will go down into the world, and will fulfil Thy command.’”
There are souls that have been put away with thee under My throne, and it is their sins which will bend thee down under a yoke of iron and make thee like a calf whose eyes grow dim with suffering, and will choke thy spirit as with a yoke; because of the sins of these souls thy tongue will cleave to the roof of my mouth. Art thou willing to endure such things? … The Messiah will say: Master of the universe, with joy in my soul and gladness in my heart I take this suffering upon myself…. Such are the things I desire, and for these I am ready to take upon myself [whatever Thou decreest]. (Discourse on the Abbaton)
The question of why Jesus
had to die is another question altogether. When Jesus asked the Father to
remove the “bitter cup,” the Father inexplicably declined. Islam asks, if God is truly all
powerful, why could He not wave the requirement of blood for sin? This is a
more profound question than why he commanded the sacrifice of Isaac. We only
know that God’s power is predicated on laws and concepts of justice and mercy
that we don’t yet presently comprehend.
