Deuteronomy is the best book of the Old Testament.
Some thoughts,
My OT professor, Roger Cotton, once told his class the following.
“The heart of the Old Testament (Tanakh) is the law. And the heart of the law is Deuteronomy. If we understand Deuteronomy, we will understand why the prophets rebuked Israel and the nations,”
I would add that, if we understand Deuteronomy rightly…
We will understand:
why David sang..
why Israel responded the way she did to Jericho, Ai, Egypt, the Amorites, and the Amalekites…
We will understand also why G-d used Assyria, Babylon, Persia, and the Greeks.
My best friend once said,
“if you want to understand the blessings [of G-d through obedience] and the curses [that G-d allows through disobedience], you need intimate knowledge of Deuteronomy.”
The church does not understand grace to an extent, because the church does not understand the work of obedience, and the standards of the law.
The law is our schoolmaster to bring us to Christ.
REVISION 11/15/18:
Younger David, really? This is your wise and knowledgeable thought??? “We must be more obedient? Seriously?
You are so stupid.
We do not understand the grace to an extent not only because of obedience and standards, but moreso because we do not understand the nature of the Trinity.
