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 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. For Joshua 2, this will involve an explanation of what true faith is.
1 And Joshua the son of Nun sent two men secretly from Shittim as spies, saying, “Go, view the land, especially Jericho.” And they went and came into the house of a prostitute whose name was Rahab and lodged there.
