And maybe if I was a Muslim I might wonder why I don't hear more about how Abraham was told to sacrifice Isaac in Judaism. Now I know very little about Islam, and my minor Wikipedia investigation on this subject has lead me to believe that there is some question in Islam about which one was to be sacrificed, but I'm also reminded of the story of Cain and Abel. Sibling rivalry has apparently been around for a very long time. And I'm pretty sure it wouldn't come as a shock to anybody who knows about the two different accounts of the event that to the casual observer it looks as if the roots of the discrepancy might reside in jealousy. The jealousy resulting from the question of who God loves more, the Muslims, or the Jews (and by extension Christians).
Normally people look at things in the context of their own religion. In that context either story may make sense, but could it make sense in the larger context of a particular group of people wanting to be God's favorite? And isn't it odd that we seem to determine how much God loves us by whether or not God asked Abraham for our ancestor to be sacrificed? I'm not trying to belittle any religion here, but I can't help but wonder sometimes if God isn't trying to tell us something.
