The story has been told of a do it yourselfer who went into a hardware store early in the morning and asked for a saw. The salesman took a chain saw from the self and commented that it was their "newest model, with the latest in technology, guaranteed to cut ten cords of firewood a day." The customer thought that sounded pretty good, so he bought if on the spot.

The next day the customer returned, looking somewhat exhausted. "Something must be wrong with this saw, " he moaned. "I worked as hard as I could and only managed to cut three cords of wood. I used to do four with my old fashioned saw." Looking confused, the salesman said, "Here, let me try it out back on some wood we keep there." They went to the woodpile, the salesman pulled the cord, and as the motor went Vvvroommmm, the customer leaped back and exclaimed, "What's that noise?"

The customer trying to saw wood without the power of the saw to help him is very much like the believer who attempts to live the Christian life without the daily empowerment of the Holy Spirit.
