The Gentiles Came, Colonized, and Desolate Places became Inhabited

"For more are the children of the desolate, than the children of the married wife" (Isaiah 54:1). To me, that seems to be saying there are more people adopted to the covenant and to the House of Israel than there are those who are of literal descent. 

The next verse is often used to speak of how the Church is throughout all the world, and of how everyone need not come to Salt Lake City to be part of the gathering. That is surely true. "Enlarge the place of thy tent, and let them stretch forth the curtains of thy habitations," says that passage.  I wonder if it also could be saying that the adoption of people into the House of Israel is the enlarging of the tent, and the stretching of the curtains. To adopt the Gentiles, it requires such an expansion. With what is on each side of this verse, it would seem that is one of the meanings of what is being said. 

And, the next verse says, "Thy seed shall inherit the Gentiles and make the desolate cities to be inhabited." The land of Israel was hardly populated for centuries. It was not until the return of the Jews that it became populated. But, this verse speaks not of that, for this verse refers to the Gentiles inhabiting the "desolate cities." Rather, It seems to me to be referring to the United States. The U.S. was not heavily populated, as a whole, before its settlement by the "Gentiles." It is not so inaccurate to call it desolate, I don't believe. But, with the arrival of the Pilgrims and the colonization of America, this scripture was fulfilled. "Thy seed shall inherit the Gentiles and make desolate cities to be inhabited." The Gentiles were adopted to the House of Israel, and came to America and made the desolate cities to be inhabited.
