Discipleship isn’t about learning to witness, getting someone to make a profession of faith, and teaching them to witness.
Discipleship isn’t about learning doctrine and teaching others doctrine.
Discipleship is about deep Kingdom relationships that revolutionize lives and multiply transformation into other lives and into communities.
The core teaching of discipleship is about the Kingdom. Witnessing and fruit-bearing happen naturally as people experience transformation. Doctrine study happens as disciples deepen. But witness training and doctrine study, apart from Kingdom relationships that revolutionize, will never make or multiply true disciples.
