The book of Deuteronomy is a series of messages preached by Moses as he seeks to prepare the second generation of Israelites to enter, conquer, and possess the Promised Land. Deuteronomy was written to teach God's people how to live victorious lives. It teaches the believer how to conquer all the enemies, trials, and temptations that confront him day by day and that seek to keep him out of the land of blessing, the promised land of God.
Deuteronomy was written to stir God's people to rededicate their lives to God, to renew their commitment to obey God, and to keep the covenant made with Him. Chapter 8 deals specifically with how a person can guard against forgetting God. In short, the book of Deuteronomy is a book relevant for our day today as we Christians strive for our Promised Land, the Kingdom of God!
