Jericho falls through God’s intervention. The impossible happened. It reminds us of what Jesus said “With man this is impossible, but with God all things are possible.” Impossibility just isn’t in God’s vocabulary. One of the deepest theological messages of Joshua ch.6 is that God is teaching us to trust Him instead of trusting our own cleverness. God is still in the business of breaking down walls today. You never know what God will set in motion with one small step of obedience.
