God rules in the affairs of men by asking His prophets to anoint or ordain a leader and equip him to serve in leadership capacity. For as long as such people fear God, obey Him and serve the people, they remain in power. But when they become self-seeking and arbitrary, Almighty God sends the same prophet to anoint another, and in one political enclave, you have the power to rule the governments. You all know the story of King Saul and David as well as the role of Prophet Samuel in this regard. God still removes kings and raises kings.
