Remember that part of being a disciple is making disciples—obeying Jesus’s Matthew 28 command (which applies to us, as it endures “to the end of the age”). This means as you make disciples (through the enabling of the authority of Jesus), you should expect them to also begin making disciples. Consider a manager at a small business. As he trains people to do more and more of what he does, his trainees soon start to train others as well. This is perhaps the manager’s main job, and thus it soon becomes one of the trainee’s main jobs as well. Each trainee, though continually being trained by the manager, also becomes a trainer. Imagine the growth capacity of such a business. So it is with disciples in God’s kingdom.
