Ephesians 2:19-21—So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord.
Simply put Christians are people who have given their allegiance to King Jesus, the true King of the world. We live as citizens of his rule and reign—his Kingdom on earth as in heaven. By the life, death, and resurrection of Jesus, we are set free from the powerful grip of Sin and Death; so, there is no longer any need to be paralyzed by fear; there is no longer any need to suffer in guilt, and we who follow Jesus can lay down our shame because we now belong to the Father and relate to Him as His people. That is, we are walking, talking, bits of New Creation. New Creation with a new identity! As Citizens of Jesus' Kingdom, we live to tell the good news that Jesus is King, and that all can become Citizens, New Creation, and have a new identity. All to the glory of Jesus our King.

We exist to know Jesus and to make Jesus known to others!
