After the victory over Jericho, Joshua commands his army to overtake the next city, Ai. However, there is 'hidden sin' in the camp of Israel. Achan stole items that were devoted to destruction. As a consequence to that sin, Israel was initially defeated, 36 men killed, and ultimately Achan would lose his life. God takes sin very seriously. We must root out and deal with the sin in our lives immediately. In so doing, we can live in God's grace through faith, covered by the blood of Jesus, keep in step with His Spirit, and be the beneficiary of God's blessings.
