The world needs to understand the doctrine of sin. The Ten Commandments are not just a moral standard; they are the stipulations of God's covenant, flowing from His very moral being. To break them is to break covenant with a holy God. Every one of us has broken this covenant and fallen short. We cannot stand before God and claim to be better than Achan. The only hope any of us has is to recognize the seriousness of our sin—that it is a covenant-breaking act with eternal consequences—and turn to the only remedy. The remedy is to repent and believe. The death of Achan and his family at the end of the chapter only makes sense when we grasp the profound seriousness of sin. But our hope is not in trying harder. Our hope is in the one who perfectly fulfilled the covenant command: the Lord Jesus Christ. The final prayer and hymn served as a call to action: to see our sin, to recognize it as a covenant-breaking act, and to flee to our strong Savior, whose perfect life, broken body, and shed blood are our only hope. We must not be legalists who trust in our own performance, but humble believers who find our rest in Christ alone.
