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 and thereby he has shown himself to be worthy of our trust. 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 should be to show how God has been faithful to us, and what response the Lord is calling us to. Joshua 14:1–15 emphasizes the response which we are to have to God’s promises. Because his promises are sure, we are to live in the light of them with wholehearted obedience to his commandments.
