When I graduated from seminary, I started a church with about 30 people. In eight years we had over 3000 regular constituents and over 1000 of them were active members serving in active roles in the congregation. Most church specialists recommend having about one full-time minister for every 250 constituents. Every staff member, board member, and department head was passionate about their department. And they gave a high priority to recruiting leaders who were articulate about the mission of their department as well as the organization.
Passionate leaders are able to excite passion in others.
They don't even have to work at it. Each of us on staff would spend a majority of our time recruiting passionate leaders in the areas of work we were responsible for. Recruiting passionate leadership was our highest priority. An organization that has lost its cause will never grow and make an impact. The same is true for any organization.
