Why is understanding the spiritual kingdom important for Christians?

Recognizing the spiritual kingdom is essential for Christians as it emphasizes that membership in God's covenant community is based on faith and grace rather than ethnic lineage or national identity. This understanding fosters unity among believers, affirming that there are no distinctions of Jew or Gentile, as all are one in Christ. The spiritual kingdom of God signifies a new reality established through the resurrection of Jesus, allowing believers to comprehend their identity as part of a divine family destined for eternal communion with God. It also cultivates a sense of belonging and purpose as members of the body of Christ.
