Except if Americans would turn back to God, he would heal our Nation.  Satan only has the power that God allows him.  So the devil tests mankind.  So he can try and get God's people to turn against God, but those that belong to the Lord are shown the truth and are protected from the evil ones.

Just saying I believe in the Lord with your mouth does not make you one of his.  You have to give your heart and your very life to him and take the narrow road and fight the righteous battle.
