Good job Marie!  The Holy Sprit revealed this to me about 7 years ago.  That is, America is not found in Revelation BECAUSE our nation will basically collapse after the Rapture of the church.
 
Though we are imperfect sinners, no one in the world is doing more in spreading the Gospel than is the American Church.  Also, the prayers of the saints are keeping our nation strong and protected.  This is not said in arrogance or with pride.  We are sinners saved by grace.  However, IT IS the Church made up, for the most part, of simple, down-to-earth "folks" that is the backbone of our nation.  Sadly, once we are gone, our nation will collapse.
 
I pastor a church in the southeast and I have been teaching this since the Holy Spirit revealed it to me seven years ago. Though we don't know the when, I sincerely believe that this, will in fact, be the case.
