What does it mean to be a fellow citizen in the household of God?

In Ephesians 2:19, the Apostle Paul declares that believers are no longer strangers or foreigners but fellow citizens with the saints of the household of God. This signifies that through faith in Christ, individuals, regardless of their background, are united in one family that transcends cultural or ethnic boundaries. It highlights the communal aspect of salvation, affirming that we are not isolated but part of a larger body, the Church, with Jesus as our cornerstone. This family aspect encourages belonging, unity, and support among believers as we await our eternal home.
