Yet again I have been studying Genesis 22. It seems to me that most of the philosophical investigations of this story miss the mark. If this is not used as a test, it is not viewed in context.
What I find most fascinating is this: the story is not a test of whether Abram will trust God against all reason. It is a test of whether he will trust God in the absence of understanding. God is not asking us to deny reason. Reason by itself could justify only a trust that goes well beyond understanding.
