In Christianity, the "Kingdom of God" is a spiritual realm where God rules as king, representing His sovereign rule over all of creation. It is displayed in the hearts and lives of those who submit to His authority and is marked by love, justice, peace, and joy. Living according to God's will on Earth is how one experiences this realm; in other words, it is not a physical location but rather a spiritual reality where God's reign is actively present and accessible through faith in Jesus Christ.
