The Old Testament conquest of Canaan often troubles modern readers, but understanding the spiritual warfare context changes everything. The Israelites weren't engaging in ethnic cleansing but removing demonic strongholds and corrupt practices like child sacrifice. Ancient Canaanite cities housed Nephilim descendants and spiritual darkness that threatened God's redemptive plan. Just as Israel had to remove evil to establish God's kingdom, Christians today fight spiritual battles using different weapons - prayer, Scripture, and faithful living. The real question isn't about ancient warfare, but what spiritual strongholds need to be conquered in our own lives.
