Lifestyle changes are not easy to do.  After living for years one way, to give it up and adopt to a new way of life is very difficult.  But that is what God called the children of Israel to do.  They needed to change who they were and whose they were.  They were slaves to the Egyptians.  As slaves they had to do what their master told them to do.  Now at Mt. Sinai, they are now a freed and redeemed people who were serving a new master, God himself.  And so they need new rules to follow.  And as stated in my message he only gave them two major rules.  Put me (God) first and to look out for those around you in a loving way.  And while they were expanded on here (and in the following chapters and books of the Bible), they are worded this way in Deuteronomy.  These rules have not changed in the 3500+ years since then for God’s followers.  We are to put God first in everything to do and to love our neighbors as ourselves.  And this needs a permanent lifestyle change not so quickie diet.
