The act of creating skilled workers (disciplined followers) was a apprentice approach using extended amounts of time, unconditional love and modeling. "Do as I do" vs. "Do as I say."
We should be careful to use tools in a way that will produce optimum results. We CAN hammer in a nail with a screwdriver, but it is not necessarily the best choice.
