My theological beliefs are such that I don't believe God controls viruses or changes outcomes if lobbied by enough people.  I do believe that God (for lack of a better term) is constantly "nudging" all of us toward goodness, and it is up to us to position ourselves to be able to discern those nudges and respond.  So my prayer for Donald Trump is that this experience (of contracting coronavirus) helps him to become more empathetic and circumspect.
