Reinterpreting Abraham and Isaac's Story

The best understanding I could wring from the story of Abraham and Isaac is to see it as an injunction against human sacrifice, a way of saying that if you understand this as God's wish you had not correctly understood.  This, of course, was not what the writer had in mind but then it was a different time, a time when God had something different to say.  Now we hopefully know there is more to parenting than an act of creating and that it would be diminishing to suggest either God or Abraham had been involved in a sacrifice destructive of their own essences.
