The Bible shows that true successful leadership in public office is done by those who fear the true Lord & who do not worship false gods/idols. The OT is replete w/ such examples. The Israelites had secular kings, not presidents, but the leadership principles are oft' transferable.
And that doesn't mean that these kings' or tp leaders' ministrations were/are any less a "ministry." Romans 13 makes it clear that public office is also a "ministry." Those who contend against this are openly militating against this Scripture. It doesn't mean that public officeholders administrate in a parochial way; it just means that public office is a "ministry of service" just like the soup kitchen down the street. History (biblical & otherwise) shows that the more pagan or counterfeit god that a leader holds, the more trouble that leader's "exhaust" settles on the people-at-large. Kings & presidents need all the grace, mercy, & guidance possible, since God gets more credit for preserving & directing leaders than we care to give Him credit for. Therefore, one who worships a false god & has no true relationship w/the living God is stifling access to God's resources; & a nation may suffer for that.
