As believers, our citizenship is not ultimately in the place we were born or where we live, but in a place we've not yet been. We're citizens of the country to which we're heading. Paul's earthly citizenship lie in one country that would be gone as he knew it within a decade (Israel), and in another that was being built up for its great fall (Rome). But his true citizenship lie in a better country, the heavenly one that lay ahead of him.
