If you were the leader of a people, were approaching the end of your life, and had one last opportunity to pass on what you thought was most important for those people to hear, what would you say? That is, in effect, the book of Deuteronomy.
It's interesting to me that Moses begins by recounting Israel's failure. He basically tells Israel, "Here's the first thing you need to know...don't be like the generation before you. Don't ignore God. Don't be stubborn. You've seen how that goes." However, he balances that with, "The Lord keeps his promises anyway. You have seen what God did with King Sihon. Now is the time for trust."
I look forward to hearing what else Moses has to say.
