Someone once told me a story that went something like this:
Several men had gathered together at their church to relocate the congregation's playground equipment. One task was to move the giant swing set. The legs of the swing set had been pulled from the ground. However, they were still encased in concrete. The swing set could not be moved and reset until the old concrete was removed.
One of the men, "Martin", volunteered to take a swing at busting the concrete from the metal legs. He picked up a sledge hammer and went to work out of sight of the rest of the men. After a few minutes Martin returned and confessed that he could not crack the concrete even a little bit.
Another man, lets call him "Jack", offered to try. He disappeared in the direction of the swing set. After a long absence Jack returned. "Did you get it?" asked Martin. "Yep," replied Jack, covered in sweat. "It's all off."
Martin and the others were shocked. "How did you do it?" they asked. "Well," Jack said, "When you want to remove concrete, you can't just hit it." He paused for a moment. "You have to HIT it."
The moral of the story? In life, or in the church, if you want to do something, don't just do it. DO it.
