The book of Joshua is a very positive book in the Bible. It’s 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. It is also a book about our responsibility towards God. The Lord has made promises to us, he has shown himself to be worthy of our trust, and in this book we 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. Joshua 10 shows us an example of Joshua and Israel’s faith. They trust the Lord’s promise to be with them in battle and therefore they go and fight against an enemy who outnumbers them and is much stronger than they are. They act in faith. The Lord then shows his faithfulness to his promises by miraculously intervening to destroy the armies of the Amorite kings and help Israel to also take their cities. Given the emphasis of this chapter on the Lord’s listening to the voice of a man (Joshua 10:14), it seems appropriate that your sermon will focus on prayer. Prayer to God is part of the response that God expects from us to his faithfulness.
