There is no discplemaking without small groups. It is the way Jesus did it. He gathered a group together and taught them. He taught them in the context of a group; in the context where they could discuss what was taught. This is how life-change happens. This is how Jesus did it and it is how we can do it.

Consider these words from Robert Coleman:

It all started by Jesus calling a few men to follow him. This revealed immediately the direction his evangelistic strategy would take. His concern was not with programs to reach the multitudes, but with men whom the multitudes would follow. Remarkable as it may seem, Jesus started to gather these men before he ever organized an evangelistic campaign or even preached a sermon in public. Men were to be his method of winning the world to God.

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.
