Do you actually see DT leading America to repent when he never asks forgiveness himself? My prayer for him is that he openly acknowledges the One True God like Nebuchadnezzar. What a way to glorify God!
Nebuchadnezzar was a dictator over many nations. Donald Trump is a world-class businessman who stands to be duly elected by the people. Your comparison is a red herring.
Besides, DJT shows more love for people than many so-called Christians in that he doesn’t “sound a trumpet” to promote his generosity.
Now that he is a public figure, specific instances of heretofore unknown generosity and “loving his neighbor as himself” (which is the Law of the Lord), have been brought to the surface by OTHERS, NOT BY HIM.
