The Kingdom Model of a true Servant Leader is presented in the gospel of Luke 22: 26 as this. Jesus said to His disciples, "But you are not to be like that. Instead, the greatest (meizon) among you should be (ginomai) like the youngest, and the one who rules like the one who serves." It is not that a leader does NOT have authority, but that he exercises it in a different way. The authority is not established by virtue of office but by virtue of service. Here is the difference which is indeed very profound. One can exercise authority in such a way as to advance himself and his own agenda, rather than serve and to benefit those whom he is serving.
"For whether is greater, he that sitteth at meat, or he that serveth? (Luke 22:27) The answer, it is not the one who sits at the table that is greater, it is the one who serves.
Everything rises and falls on a great leader. He/she must continually ask, "Am I a serving leader, or a self-serving leader?" A leader cannot be microwaved! They don't become great overnight or at a moment's notice - it is one day at a time over their entire lifetime. It is about seeing the future and creating a compelling vision and a personal statement about it so that he that sees the vision may run with it. And though it tarry, we should all patiently wait for it. In the end, it would prove to be truth and not lie and it shall come to pass.
