A true and safe leader is likely to be one who has no desire to lead, but is forced into a position of leadership by the inward pressure of the Holy Spirit and the press of the external situation. Such were Moses and David and the Old Testament prophets. I think there was hardly a great leader from Paul to the present day but that was drafted by the Holy Spirit for the task, and commissioned by the Lord of the Church to fill a position he had little heart for. I believe it might be accepted as a fairly reliable rule of thumb that the man who is ambitious to lead is disqualified as a leader. The true leader will have no desire to lord it over God's heritage, but will be humble, gentle, self-sacrificing, and altogether as ready to follow as to lead, when the Spirit makes it clear that a wiser and more gifted man than himself has appeared.
