What does the Bible say about our citizenship in heaven?

Philippians 3:20-21 emphasizes that our citizenship is in heaven, from which we await a Savior, the Lord Jesus Christ. This heavenly citizenship signifies that believers are part of a community of grace, receiving all spiritual blessings through Christ. Just as being a Roman citizen held significant privileges in the ancient world, being a citizen of heaven confers spiritual rights and responsibilities that are far more precious and far-reaching, including redemption, sanctification, and justification.
