Joshua and the Israelites have crossed into the Promised Land and have conquered the first city, Jericho. God performed another miracle by causing the walls around the city to fall. The next city to take is Ai, but this time God’s people are defeated. Joshua knows God is no longer with them, but why? One man named Achan took some of the plunder when God instructed them not to. Achan’s one small sin had the potential to derail what God had planned for his people. In the same way, our small, and seemingly harmless, mistakes have the potential to derail what God wants to do in us.
