My favorite Old Testament book for sometime has been the book of Deuteronomy. It is a fascinating text after the famous "Exodus" from Egypt. Moses stands up in a series of oracles and reminds the people where they are from, to whom they belong, and what they are promised. It's an ancient text that speaks volumes to our current generation. The format of the book is identified as an ancient Near east contract or treaty referred to as a Suzerain/Vassal Treaty. Essentially it is a contract between king and servant. The broad lay out is a definition of parties involved, commitments, and consequences (blessings or punishment).
Side note: The themes of social justice, communal care, and simple obedience are powerful to say the least. The history sharing is a powerful reminder to divine intervention for all humanity. There is a wealth of principles that deserve one's full attention.
I have taught various classes on Deuteronomy since 2011. I have passed down to students a cliche that has been taught for years...obedience = blessings. While it's not entirely wrong. It has the wrong beginning. The starting point isn't our obedience but His blessings. Thus, the paradigm is more accurate to say, we obey because we have been blessed. As a generous God, He both blesses on the front and back end of our obedience. This can be defined simply as God's Love. I John 4:19
So, I was wrong. I am not dutiful bound to obedience in hopes of a perk. I have been blessed. Thus, I'll look back and move forward in obedience because I was first loved.
