The Launch Large model of church planting allows the planter to utilize the zeal they have amassed based on the confident call they have on their lives and the enthusiasm of the people they have been able to gather to help them plant. If the Church Planter and their Launch Team have done the groundwork in the community, the community should also have a sense of anticipation for the church launch.
It is not unusual for a church to have 50% fewer people the 1st Sunday after its initial launch. Thats why Launching Large, with at least 200 people, seems to give the right amount of people momentum for continued church growth and avoids growth stagnation. This is of course contingent upon there being other evangelistic activities, as well as, the leadership abilities of the Pastor.
