Isaac asked Abraham where is the sacrifice and was reassured not to worry because God would provide the sacrifice - and God did. Just as promised.
So your modern day apologetic is to assert that God rendered physical sacrifice unnecessary hundreds (if not thousands) of years BC. Congratulations, you’ve just rendered Jesus’ death unnecessary.
And yes, I think you can argue that God trusted Abraham.
Trusted Abraham to do what? Keep their mutually agreed upon secret to pretend to murder and burn alive Abraham’s son?
Can't you see what the take-home message of the story is?
Obey your father or he’ll pretend to slit your throat and burn you alive because the voice in his head wanted to play a terrifying and unnecessary prank on you?
So let’s recap your apologetics and what they necessarily entail. When God tells Abraham to murder his son as a physical sacrifice to God (because such a being requires its creations to brutally murder each other as a sacrifice to it for no possible legitimate reason, just ineffable whim), Abraham knew God was lying to him and instead what God wanted was not to test Abraham, but to pull a prank on Isaac.
So Abraham—knowing that God wanted to pull this terrifying, cruel prank on Isaac—decided to go along with God’s lie by pretending that he was going to slit his son’s throat and burn him alive, but at some point in the charade, Abraham must have forgotten that his was what God was going to do, because God has to intervene and stop Abraham from actually murdering his own child.
So now it’s a story about a prankster God and a loving father who knows God doesn’t actually want him to kill his own son, but to make it authentic and REALLY scare the absolute shit out of his own son for no discernible reason other than terror for terror’s sake, Abraham suddenly behaves as if God has not lied to him, he doesn’t know that God is pulling a prank and proceeds to actually slit his son’s throat, only to be stopped at the last minute by God.
I mean, it’s a hilarious practical joke, no doubt, but if literal, it means Abraham is a psychopath and Isaac’s life is psychologically destroyed and if parable, it means that God rendered human sacrifice completely unnecessary centuries before Jesus, so bang goes sacrificial atonement “for our sins”—which means there can be no life after death—and Jesus must therefore have been a false prophet and all that fun stuff.
I get why you’d spin the nonsense about Abraham knowing it’s all a prank and yet God unnecessarily having to stop Abraham (if it’s a prank, Abraham was never going to actually kill his son, so there would have been no reason to stop him) and all, but no. The lesson to be learned (if there can be any kind of lesson learned aside from do what your told by the cult leaders) is that God knows true faith (aka, obedience)—that God knows what’s in your heart and what’s in your head.
Which means that Abraham had to firmly believe that God wanted him to kill his son and was going to kill his son precisely because God wanted him to and only at the last minute did God stop him because he could see that Abraham’s obedience to God was absolute. The asshole was going to murder his own son for God, but God didn’t actually need a human sacrifice to act. He mislead Abraham into thinking that was the case in order to test Abraham’s faith, but stopped the sacrifice of a father’s innocent son as being unnecessary.
Bang goes the NT.
