Book 14 says the decisive qualification for leadership is not degree, competence, or rank, but devotion. The leader is the person who has loved, served, and borne responsibility more deeply than others.
This is not anti-skill. It is anti-detachment. A movement can survive a leader who lacks polish more easily than it can survive one who lacks costly loyalty.
It is also a useful cross-domain check. In church, mentoring, and team life, the real question is often not “who knows the most?” but “who has paid the most for the good of the whole?”
