In our Christian theology, the concept of "Kingdom Culture" or "Heavenly Citizenship" refers to the idea that we as Christians, while living on Earth, are also citizens of the Kingdom of God, which is a heavenly, spiritual realm. This concept is deeply rooted in the teachings of Jesus Christ and the New Testament of the Bible. It reminds us that our ultimate allegiance is to God's Kingdom and that we are called to live according to its values and principles even as we navigate the challenges and temptations of this world.
