Roles of a church planter

In additional to the expectations that are common to all Christians (family life, integrity, personal spiritual growth and health...) church planters (people who start new congregations) have to think like:

a) missionaries -- ability to get inside the minds and hearts of those who do not believe for the purpose of helping them eventually come to belief
b) pastors -- ability to lead, care for, teach, and nurture those who do believe
c) structural engineers -- ability to develop the organizational structure which will allow a sustained Christian community to develop and grow.

The challenge is in knowing which of these roles to emphasize in any given moment.
