Can a good Christian reject human authority?
“Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God.”
To say God gives authority goes against the theory of "free will".
Dictators use their own "free will" to ascend to power. They aren't placed there by god.
Elected officials are placed there by people using their "free will" to vote for their leadership.
It is ironic to quote the NT Bible, when referring to God giving authority to government ... when much of the NT was written when a pagan pantheon ruled.
So IF they did get authority from a deity to rule - it would be from their pantheon, not the God of Abraham.
