Eugene Peterson, in his book, Run with the Horses, shared a humorous story that vividly illustrates the meaning of repentance.
A few years ago I was in my backyard with my lawnmower tipped on its side. I was trying to get the blade off so I could sharpen it. I had my biggest wrench attached to the nut but couldn’t budge it. I got a four-foot length of pipe and slipped it over the wrench handle to give me leverage, and I leaned on that—still unsuccessfully.
