Mother churches are significant beneficiaries of church planting. Bob Logan’s research suggests that churches that plant churches grow 3x faster than churches that do not. Also, when churches send people, it requires unengaged participants to step forward and fill the roles of those who left on mission. Those who leave on mission also set an example of living by faith, that is often emulated by those left behind. Even though the new volunteers stepping forward may be inexperienced, they are stepping into a much more exciting scenario—filling in because someone left on mission rather than filling in because the previous person burned out.
Church plants also reinvigorate current churches by innovating new methodologies to meet changing populations. Larger and more established churches tend to use methodologies that are tried and true and they continue to exercise ministry forms that continue to work, particularly among the people who already participate. Church plants often target different people and are usually more nimble and desperate and therefore pioneer new ways of meeting needs and addressing ministry challenges. These innovations often are adopted by the other churches around. Also, smaller churches often meet people who will never attend a larger more established church. Then, these new Christians will often move on to the more established churches that have more ministries in order to have their broader set of needs met. They bring with them young faith and fresh ideas from the church plant. Alpha, Celebrate Recovery, are significant examples of this, but it often happens in much more smaller, less nationally noticeable forms. Small Groups, contemporary worship, and even coffee in the worship center were forms that were experimented with first in church plants and then adopted into the broader church community.
