How do we know our citizenship in heaven is true?

The assurance of our citizenship in heaven comes from scripture itself. In Philippians 3:20, Paul makes it unequivocally clear that 'for our citizenship is in heaven,' thus assuring believers of their heavenly identity. This citizenship is established by God's sovereign grace, not by any merit of our own. The work of Christ, as our Savior, solidifies our place in heaven, while the ongoing work of the Holy Spirit in our lives bears witness to this truth. Therefore, our faith rests upon God’s promise and not on subjective feelings.
