I've learned a lot about making disciples from Curtis Sergeant. You can read more about Curtis at www.obeygc2.com.
Curtis has put together 28 videos that are for those wanting to learn how to make disciples who make disciples who make disciples.
They are a great resource and I think you will find these extremely helpful. I would encourage you to take the next 28 days to watch one video each day. Most are between 3 - 7 minutes long.
You can watch all of the videos here: Multiplication Concepts
And just to get you started, I'll post the first four videos below.
