What is the descriptive definitive source of the word "Christian" and were do you see Trump becoming penitent and being converted and baptized, and following the Lord with a Bible-believing body of believers, worshiping and praising the Lord, (Acts 2:38-47) and evangelizing/preaching the gospel in humility and bold faith, (Acts 8:4) and with contrite heart confessing his faults in striving to be more like Christ? (1 John 1:8,9)?
Note that beneficial civil leaders are not always Christian, though they are well suited for the job, and Christians may not be as good a leader as a non-Christian, and thank God Trump, whom i voted for, was elected, but despite his positive qualities I do not see a Christian testimony of regeneration and its basic profound transformation, nor penitent repentance for his faults
I guess you’ve missed the prayer meetings and bi-monthly gathering of pastors at the White House? Plenty of it online. Do some homework.
