Why do you think this is twisted reasoning?
I think the point trying to be made here is what makes the “killing” of Isaac an immoral act?
The “standard of the times” by the pagans was that it was not an immoral act but it was something good and required to be performed for the gods. No one at that time thought this was immoral. So why do you think it is unacceptable? The only answer here is because God tells us thou shalt not murder.
This is kind of the point of the story here. By His command, to sacrifice Isaac, God here is proclaiming, to Abraham and all of us, his absolute dominion over the lives of men who are the work of his hands. He is telling us that He is the author of life He can create it and He can take it away.
Then by His revocation of the order He teaches us that He does not wish this dominion to be acknowledged by the actual sacrifice of human life.
The point here is Abraham came from a land where killing children was not immoral. God was showing Abraham that although He has the power to ask for Isaac’s life that is not what He wants, He was showing him that what is most important is obedience and faith.
To me it would be similar to stealing someones money out of a vault. We would both agree this is an immoral act, however is the act still immoral if the owner of the vaults asks you to break in and steal the money?
The answer to this question lies in the intent of the owner (God). If the intent is to have you take the money so the owner can defraud his insurance company then it is immoral. If the intent is to see the security of the safe, then it isn’t immoral.
In the end God knew that Isaac wasn’t going to die He was testing, to prove to Abraham, how strong his faith really was. It all comes down to intent.
This comparison is confusing? Don’t many believe abortion is an acceptable norm in this day and age? Don’t they justify that they aren’t killing anyone? Don’t they believe it is not a sin?
Personally I don’t think it should be an acceptable norm. But why? For me because God says it is murder.
