I have no information on that Bible study, but I have seen it in the catalog and have wondered about it myself.
I agree with pollysoup about the family discussions. I have an 8 year old girl, a 7 year old boy and a 4 year old girl. After dinner we read a chapter of the Bible (although because of the ages of my kids, some things are skimmed over more, especially sexual stuff). We have read through the Bible once this way (took us quite a while, my son was probably about 4/5 when we started!) and now we are on our second time round.
We just finished Leviticus and one of the things my husband keeps emphasizing is that all of these rules are for a purpose: this is a fairly new nation (just out of Egypt) and they need some guidelines on living, they need to be set apart from the nations around them, as well as they need to understand who this great God is. Then he turns it around to us - how should we live today? We don't burn sacrifices anymore, but the outward acts of the Old Testament were a symbol of the inward heart. So we are constantly challenging the children on what is in our hearts. Do we give God the honor and reverence that He is due? Do we treat each other as God's creation? etc. We also do what pollysoup does and talk about the people - their choices, their attitudes, the lessons we can apply today. It is amazing how much they get out of these discussions!
Sorry, I know you probably wanted more info on the actual Bible study, but just wanted to throw this in.
