The book of Joshua reveals four powerful gospel threads that point to Jesus Christ. First, the memorial stones teach us about redemptive remembrance, showing how God wants each generation to share His story of faithfulness rather than just religious rules. Second, the inclusion of Rahab demonstrates God's heart for outsiders, while Achan's exclusion shows the consequences of rebellion. Third, Joshua's encounter with the Commander of the Lord's army reveals that we must submit to God's agenda rather than enlisting Him into ours. Finally, the conquest narrative illustrates God's justice and mercy, pointing to Jesus as our greater Joshua who won the ultimate victory.
