And say that no angel would come to stop you, unlike Abraham's case.
Atheists, pretend there is an almighty and all-righteous God, and there is a good reason that he can't share with you. Would you do it?
I could not tell you. I would have to be tested then I would know if I would do it. Keep in mind that God spoke to Abraham, so it wasn't Abraham's idea to do this. Another thing is God promised that he would provide a sacrifice, so Abraham was standing on a promise when he did this. So Abraham was not lying when he told Isaac "God will provide the sacrifice".
