Why is the spiritual nature of Christ's kingdom important for Christians?

The spiritual nature of Christ's kingdom is vital for Christians as it shapes their identity and calling. By recognizing that His kingdom is not about outward appearances or earthly power, believers are encouraged to live in accordance with spiritual truths. Romans 14:17 states, 'the kingdom of God is not in meat and drink, but righteousness, peace, and joy in the Holy Ghost.' This means that Christians are to seek righteousness and cultivate their relationship with God rather than striving for worldly achievements. This understanding fosters deeper communion with Christ and emphasizes that Christians are citizens of a heavenly kingdom, prominent in their behaviors and interactions in the world.
