What does the Bible say about being a citizen of God's household?

In Ephesians 2:19-22, Paul emphasizes the transformation of believers from being strangers and foreigners to becoming fellow citizens with the saints and members of God's household. This change signifies a deep and intimate relationship with God through Christ. Believers have full rights as citizens in the heavenly kingdom, which includes having God as their Father and being part of a divine family. They are no longer alienated from God's promises but have a place within His community of grace.
