“You know that the rulers of the Gentiles Lord it over them”.
Why humans seek power? With power comes influence. With influence comes relevance. Just nearly all humans want to remain relevant. It didn’t come surprising to Jesus when the mother of James and john brought her two sons to him in order to occupy seats of power. Jesus uses that opportunity to call the attention of his apostles to the mundane pursuit of power which is not for the purpose of the kingdom. We exercise power at different levels of our existence. We are not to follow the world in the existence of our power.
