I agree that probably simplicity is best. However, that foreshadowing raises further questions (to me) since G-d REJECTS this kind of sacrifice and thus an animal is offered in Isaac’s place. Of course, Christ is likened to the Lamb of G-d but, in reality, is He an unwitting Lamb, Who does not know what will happen to Him and does not ask G-d why He has been forsaken? Besides which, as I have previously noted, the blood of the lamb is connected to the Hebrews’ mocking of an EGYPTIAN god during the initial Passover.
Kind David stated that he would not offer G-d a sacrifice which cost him nothing. That is the very definition of sacrifice, and the year-old, blemish free animal was the best of the best - specified in the sacrifice. Yet, the L-rd does not enjoy the sacrifice, and He does not benefit from it. It is for our atonement - therefore it must have repentance and some cost involved.
In Christianity, the Christ, proceeding from the Father, knows all things was was well aware of the sequence of events and their eternal import. His face was “set like flint” to go to His death at Jerusalem. At Gethsemane, He commanded the apostles, “Rise! Let us be going! See, my betrayer is at hand.”
It sounds trite due to repetition, but G-d so loved the world that He gave His only Son that those who believe in Him should not perish. Love, which has its source in G-d, and of which the L-rd consists, desires the good of the other. love does not count the cost. Thus, the only Son was knowingly and freely given.
In this case, the sacrifice was earth-shaking - literally, and forever changed our relationship with the Father. We lowly Gentiles, having never been counted among G-d’s chosen, and so poorly and rightly spoken of in the scriptures, now had hope in a true G-d, rather than the plethora of hopeless idols which gave some outlet to man’s innate desire for a G-d.
