Trump is reminiscent of Cyrus the Great, who Ezra and Isiah called anointed by God. That does not mean he was a Godly man, but he was used by God. Cyrus conquered Babylon, freed the Jews, ordered the Temple rebuilt (and funded the building) among many other things. I believe Trump is annotated by God. Now, as far as being the greatest ever, not even close. That should be reserved for Christ.
King David was pretty human too.
