Yes… the hand of God has been upon this nation for over 350 years, since we came over in 1620 on the Mayflower and we have survived since.
Up until the 1950's we were VERY Christian. Christmas was illegal in Oklahoma as recently as 1912.
I personally believe that we have been allowed to go astray for the last 50 years just so that God could return us to Him to undeniably prove that the United States is a blessed nation in the end times, which have begun/very close to beginning.
