I'd been travelling for long hours on a lonely country road when I had a flat tire. So I had to stop and get the tools to  36 the problem. It certainly wasn’t  37 doing this with a white shirt and suit on.
Nightfall was approaching. Suddenly a car pulled  38 from behind me. A man got out and offered to  39 me. Seeing his unpleasant appearance and tattoos(纹身)on his arm, I became  40 as thoughts of robberies flashed through my mind. But  41 I could say anything he had already begun to take the tools to change the  42 . While watching him I happened to look back at his car and noticed someone sitting in the passenger seat. This had  43 me.
Then, without  44 , it began to rain. He suggested that I wait in his car because my car was unsafe. As the rain increased, getting us wet within seconds, I  45 agreed. When I settle into the back seat, a woman’s voice came from the front seat. “Are you all right?” She turned around to me. “Yes, I am.’’ I replied with much  46  when seeing an old woman there. It must be his Mom, I thought. To my  47 , the old woman was a neighbor of the man who was helping me. “Jeff insisted on stopping when he saw you  48 with the tire. ”“I am grateful for his help, ” I said. “Me, too!” she said with a smile. He helped drive her to see her husband twice a week in a nursing home. She also said that he  49 at the church and tutored disadvantaged students.
The rain stopped and Jeff and I changed me tire. I tried to offer him money and of course he  50 it. It was shameful that I judged people by the way they  51 . As we shook hands I began to apologize for my  52 . He said, ‘‘I experience that same  53 often. People who look like me don’t do nice things. I  54 thought about changing the way. But then I saw this as a chance to make a  55 . So I’ll leave you with the same question I ask everyone who takes time to know me. If Jesus returned tomorrow and walked among us again, would you recognize Him by what He wore or by what He did?’’
