Both globally and locally, making disciples who can make disciples takes a training cycle. Curtis Sergeant compares it to teaching children to ride a bike. Jon Ralls compares it to potty training. We can see examples of it with Jesus and his disciples, and also in the missionary journeys of Paul — model, assist, watch and launch (or, leave). Why do we not see it in most American churches? The list of reasons why might be so long, that the task of re-engineering might seem impossible. Mainly, I think, because small groups are not emphasized and there’s not an intentionality built into the disciple maturation process. If there was, we might see disciples making disciples to the 3rd and 4th generations.
