What are some ways that the theme of victorious conquest in Joshua applies to present-day Christians?
The theme of victorious conquest over the land of Canaan in the book of Joshua is very important to us as Christians today for several reasons. First, conquering the land was a fulfillment of God’s promises to Abraham in the context of the covenant. God fulfilled these promises by his mighty hand through Joshua and the army of the people of Israel. But the other important thing for us as Christians is that, in the victory of Israel over the people of the land of Canaan, we see the faithfulness of God in fulfilling his covenant, and we see God’s hand going before Joshua and the army in triumphing and winning over the people. For us, this means an important thing, because, in Christ, we always walk in Christ’s triumphal procession. God leads us in this triumph. Just as Joshua led the people in their war against the Canaanites, who exemplified the ungodly on earth at that time, Christ did the same thing on the cross. He triumphed over his enemies — Satan and his followers — over evil and over sin. This gives us, his followers, the privilege to walk, always, in Christ’s triumphal procession.
