Why was Abraham blessed in the first place?

After looking at the Abrahamic covenants in Genesis 15 and 17 last week, we backtrack slightly in the story to explore what God had in mind when He called Abraham. The "call of Abraham" is in Genesis 12, and we end up discussing some intriguing details of Genesis 23. This episode is a slightly disjointed because Cameron's recording somehow vapourised, so you'll need to exercise your imagination about his comments in places. As always, comments are welcome at [email protected] - and bonus marks if you can deduce where Cameron would have quoted Adrian Plass or Lewis!
