Trump is the President he is not a personal President.
'Personal president' is almost a cringe-worthy phrase to hear.
Just imagine a political opponent of Trump giving a speech where he says that Trump is not a 'personal president'-- with no explanation. It would just sound weird, cringe worthy. If newscasters did not like the speech, they might play that clip over again.
How many evangelicals say, "You have to accept Jesus as your Personal Savior" with no expectation as if their listeners understand the extraneous use of the word 'personal'. Sometimes the person who uses the phrases uses it robotically, following the traditional script that dates back maybe 100 or 130 years, without thinking of what it means or without realizing that the phrase 'personal Savior' was not important enough to make it into the Bible.
And this reinforces American individualism, and the idea that Christianity is 'all about a personal relationship with Jesus Christ'-- which is unbiblical because our fellowship with other believers and how we relate to our fellow human beings is important to God, too.
Even with explanation, 'personal president' is a pretty weird-sounding phrase. 'Personable' maybe. 'Personal'...no.
Is there any reason to defend the use of 'personal Savior' in Gospel presentations other than the fact that it is (relatively new) church tradition that goes back a few generations? The average Joe on the street is probably not going to guess that 'personal Savior' is supposed to have something to do with having a personal relationship with the Savior.
