After the victory of Jericho, Israel seems unstoppable. Joshua 7 and 8 show how quickly triumph can turn to defeat when God’s people drift into self-reliance and hidden sin. This sermon explores the sobering consequences of disobedience, the corporate weight of sin, and the mercy of God who restores His people when they return to Him. Above all, it points us to Jesus, the greater Joshua, who deals with our sin fully and leads us in true victory. This is a call to reject self-sufficiency, cling to God’s Word, and remember that God is not serving our mission. We are invited into His.
