The book of Joshua is a very positive book in the Bible. It is a book about the faithfulness of God, written to strengthen our faith in his promises, particularly the promise that Jesus Christ is preparing a new home for us where we can enjoy rest in his presence (Hebrews 4:1–16). It is also a book about our responsibility toward God. The Lord has made promises to us; he has shown himself to be worthy of our trust, and in this book we will see how the Lord calls us to now be faithful to him.

In light of the purpose of Joshua, the goal of your sermon must be to show how God has been faithful to us, and what response the Lord is calling us to. With Joshua 21:43–45 having asserted that the Lord kept all his promises, Joshua 22:1–34 focuses on the response of obedience that ought to come from God’s people. Specifically we are encouraged to pursue unity, to treat each other as brother and sister in God’s church, and not to look down on those from a different ethnicity, gender, social class, or level of education.
