Much lies hidden in these few words of Christ. In the first place, Jesus says: Man is the child of two worlds, one is of earth, visible; the other is of heaven, invisible. He must adapt himself to both. As child of God and citizen of God’s kingdom his first duties are to his highest Lord. May one then conclude that Christians need not bother about worldly affairs, since they are exalted so highly? No! Just because you are a citizen of God’s kingdom, you also have duties to fulfill toward your earthly superiors. You are a member of a family, of a parish, of a body politic, and therefore God has laid upon you obligations toward parents and toward civil authority.
These obligations are not at variance with each other. The Christian must also be an upright citizen, an upright administrator, and upright employee in a factory or business. Obedience to human authority is not service toward mere men, it is true service toward God. The Christian says: You are substituting for God. God has given you power and authority; because of that and only because of that do I respect you; I honor in you the ruling power of God by only to that degree in which it has been given you. If you order anything against the divine will, you no longer are God’s delegate; then do I listen to God.
Our Savior included all this, even though it is not explicitly stated. You should be good citizens of the state and you must be good citizens of the kingdom of God. “Render to God the things that are God’s.” What are “the things of God”? All, all that you have and are; yes, everything is from God and for God. Retain nothing, therefore, for yourself. Body and soul, intellect and will, heart and mind belong to Him; dedicate all to His service. Again we are face to face with the primary commandment of God’s kingdom, “Thy will be done on earth as it is in heaven!” (The Church’s Year of Grace, Volume 5, pages 101-102)
Thank you for the sermon. Indeed everything good comes from God and I must obey legitimate authority in so far as they adhere to what God plans for mankind human and orderly development. I pray that all "Caesars" may know that they act on God's behalf and should keep their policies in accordance with the will of God.
