Genesis 22 - Do not lay your hand on the boy

Genesis is a foundation for many of the symbols and images that become significant throughout the Bible. 

But it is fascinating to reconsider just how detailed these introductions actually are. What is the resolution of the imagery in Genesis, and does it add value forwards through time? Could some of it only make sense in retrospect? We focus particularly on themes of "the lamb" and sacrifice, and it seems much is left unresolved (from our Christian perspective) in the book of Genesis itself.
