I realized something the other day that I had never picked up on before.  Genesis opens up with an account of man’s creation and fall.  I’ve always taken it as obvious that Moses included the story because he wanted to detail the history of Israel all the way back to creation.  Additionally, however, I think Moses had a very practical reason for including the story: It served as a warning to the nation of Israel.  Just as God had prepared a garden for the first humans to live in, God had also prepared the land of Canaan for the Israelites to inhabit.  And just as God expelled Adam and Eve from the Garden of Eden because of their disobedience to God’s covenant with them, likewise God would expel the children of Israel from the land of Canaan if they disobeyed the covenant God had made with them.  Adam and Eve’s experience served as a literary and historical example for Israel to learn from, lest they experience the same fate in Canaan.
