Jesus’ method of making disciples–a method we should all follow–is set forth in this short verse:
He appointed twelve that they might be with him and that he might send them out to preach Mark 3:14 (NIV2011)
Robert Coleman explains Jesus’ methodology this way:
Having called his men, Jesus made a practice of being with them. This was the essence of his training program—just letting his disciples follow him.
When one stops to think of it, this was an incredibly simple way of doing it. Jesus had no formal school, no seminaries, no outlined course of study, no periodic membership classes in which he enrolled his followers. None of these highly organized procedures considered so necessary today entered into his ministry. Amazing as it may seem, all Jesus did to teach these men his way was to draw them close to himself. He was his own school and curriculum.
The natural informality of this teaching method of Jesus stood in striking contrast to the formal, almost scholastic procedures of the scribes. These religious teachers insisted on their disciples adhering strictly to certain rituals and formulas of knowledge which distinguished them from others; whereas Jesus asked only that his disciples follow him. Knowledge was not communicated by the Master in terms of laws and dogmas, but in the living personality of One who walked among them. His disciples were distinguished, not by outward conformity to certain rituals, but by being with him, and thereby participating in his doctrine (John 18:19).
It was by virtue of this fellowship that the disciples were permitted “to know the mysteries of the kingdom of God” (Luke 8:10). Knowledge was gained by association before it was understood by explanation. This was best expressed when one of the band asked, “How know we the way?” reflecting his frustration at the thought of the Holy Trinity. Jesus replied: “I am the way, the truth, and the life” (John 14:5–6), which was to say that the point in question already was answered, if the disciples would but open their eyes to the spiritual reality incarnated in their midst.

If you would like to lead your people to make disciples using the “With Him” principle, you will need, of course, to model the principle by spending time with your people.
