David G. Firth interprets the book of Joshua with a sensitivity to its place as Christian Scripture. Joshua is marginalized in many churches, often because its message is misunderstood. Firth reveals that, rather than simply being a story of conquest, Joshua is concerned with matters of identity and faithfulness. Joshua exhorts God’s people to live out their calling in light of God’s promises. While Israelites like Achan fall short, others—often gentiles—show surprising faith in God. Firth also probes the book’s theological themes, such as the promised land, government, rest, and promise. The book of Joshua boldly challenges the complacent in faith to be a nation committed to God.
