The Great Commission says that we are to "Go and make disciples of all nations..." The "go" is better translated, "as you are going". Therefore, disciplemaking is not about taking a course, or filling in the blanks in a workbook. Instead, it is about sharing one's life with others. Back in biblical times, disciples of a particular rabbi were described as "covered with the dust of their rabbi". Hence, the idea of hanging out with people and letting them see how you relate to God, family, other people, etc. is what disciplemaking is all about. The pattern that Jesus used was...

I do it

I do it and they (disciples) see me

They do it and I'm in the background.

That pattern is spelled out by the Apostle Paul in his second letter to Timothy (2 Timothy 2:2)

"...and the things that you have heard from me in the presence of many witnessess, commit to faithful men who will be able to teach others also."

They do it and I'm gone to the Father.
