This is how the Witnesses may defend this account. Abraham had reasoned in his head that god could resurrect his son. He came to this conclusion because god had, in effect, resurrected Sarah's womb. You see? He had full faith that god would resurrect Isaac, based on god's promise that Abraham would become a great nation through the child he had with Sarah. Sarah was 90-years-old when she got pregnant in her resurrected womb, so god had already proven himself. Just trying to get you ready for the show down.
Problematic isn't it?

Edited to say: I just can't read larsinger's post again. I couldn't get through it the first time. It made me ill halfway through. Of course it's god's right to limit a human's lifespan. Bloodthirsty god. UGH---I'm so glad I'm free of it!
In fact, there are Bible verses that represent precisely that? That is, if your eye offended you, wouldn't you pluck it out to save the rest of the body and preserve life? Of course!
DUH, WELL OF COURSE!!! Who wouldn't want to worship a god that requires self-mutilation. I haven't seen many bible believers plucking out their own eyes. Hmmmm---faithless mothers aren't they?
