God is serious about our commitment to Him. Our prayers must be carefully crafted and come from an obedient heart and an expectant faith. Chan summarizes examples from Scripture where God shows His holiness by punishing sin. The flood and the destruction of Sodom and Gomorrah indicate His holy wrath. The judgment of Joshua upon the family of Achan shows God’s use of His people to carry out His justice. We must be careful to make our own lives pure and pray for the purity of our brothers and sisters in Christ.
