How does God carry out his decrees?
God carries out his decrees in creation and providence.
In creation, God spoke order to chaos. From nothing came a meticulously ordered creation. From all the metered movements of each heavenly body to the life cycle of the tiniest creature, all have found and remained in perfect order at the word of God. Everything remains exactly as it has always been. Spring follows winter and the sun always rises in the east. Speaking once into chaos he set the world in motion. He carries out his decrees in creation by speaking order to chaos and sustaining the perfect natural order.
Providence is that special movement of God through mankind. The interaction of God with man is what is we mean by providence. Providence works to bring glory to God. Through men as individuals, groups, or governments. He has ordered the human realm in order to reveal himself and to bring glory to his name. In order that the righteous might praise his name, and that the wicked might fear him.
Providence can be misunderstood when we view God's intention incorrectly. God is intimately concerned with his people, but he is not so concerned that he loses track of his goal. Providence reveals God to men, in order that, glory would be brought to his name Whether men worship or tremble before God, his name will be glorified. Even in his rebellion, men will bring glory to the name of God. When they become the subject of his perfectly righteous justice.
