Scars of Love
Some years ago on a hot summer day in south Florida a little boy decided to go for a swim in the old swimming hole behind his house. In a hurry to dive into the cool water, he ran out of the back door, leaving behind shoes, socks and shirt as he went.
He flew into the water, not realizing that as he swam toward the middle of the lake, an alligator（短吻鳄） was getting close. The mother in the house was looking out of the window and saw the two as they got closer and closer together. In great fear, she ran toward the water, yelling to her son as loudly as she could. Hearing her voice, the little boy became alarmed and made a U-turn to swim to his mother. It was too late. Just as he reached her, the alligator reached him. From the dock, the mother grabbed her little boy by the arms just as the alligator snatched (抓住) his legs. That began an unbelievable tug-of-war (拔河比赛) between the two. The alligator was much stronger than the mother, but the mother was much too passionate to let go. A farmer happened to drive by, heard their screams, rushed from his truck, took aim and shot the alligator.
Remarkably, after weeks and weeks in the hospital, the little boy survived. His legs were extremely scarred (留下伤疤) by the terrible attack of the animal. And on his arms, were deep scratches where his mother’s fingernails dug into his flesh in her effort to hang on to the son she loved.
The newspaper reporter, who interviewed the boy after the trauma （外伤）, asked if he would show him his scars. The boy lifted the pant legs. And then, with obvious pride, he said to the reporter, “Look at my arms. I have great scars on my arms, too. I have them because my mum wouldn’t let go.”
You and I can identify with （认同） that little boy. We have scars, too. Not from an alligator, but the scars of a painful past. Some of those scars are unsightly and have caused us deep regret. But, some wounds, my friends, are because we have refused to let go.
