"But it is not as though the word of God has failed. For not all who are descended from Israel belong to Israel," -Romans 9:6
I am, much, a patriot. Not necessarily by proxy, not only because of ancestry (though both are factors) ....but by choice, a choice of adherence, and dedication, to a foundational, and fundamental, truth that all men are created equal, with certain inalienable rights ...given to us by our Creator.
These are truths which find their very premise in God's word. To be "American" is, at it's very origin and core, a choice, more so than even a birthright. Case in point ...one does not have to "defect", as it were, if they so choose to seek, and apply for, citizenship elsewhere.
Therefore, it stands to reason that not everyone who calls him / herself "American" is in agreement, or in alignment, with the principles which this sovereign nation holds dear.
In his letter to the church in Rome ...the Apostle Paul makes clear that being a descendant, alone, does not make one "God's chosen". Likewise, Matthew's record of the gospel boldly states... ""Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. -Matt 7:21
This is the, much debated, doctrine of election. Who can become an "American"? Anyone who agrees to her laws. Who are "God's chosen"? Any who will call on His name, seek His face, and turn from (repent) of their wicked ways.
