If you can reach people for Jesus and multiply them into three groups, then you’re 80% of the way to being a church planter. Potential planters start a missional community that multiplies to three functioning communities– and that’s the core of a church plant.
After that some planters may want to move on to plan somewhere else, leaving those groups to be led by others. Or they may choose to stay on and organize those communities. Either way, the skills involved in getting those first three groups up and running are what demonstrates you’re a church planter.
At that point you can ask, “What additional skills might I need?” These are things like preaching, coaching, or time management. You might also ask what biblical or theological competency you need to fully ramp up. TruthQuest is a great one for helping people involved in real life, day-to-day ministry ramp up on basic theology.
