Knock, Knock, Who is there?

About an hour ago my doorbell rang. It is 7:30 pm & dark outside. I turned on the porchlight & peered thru my beveled glass window in my front door. I did not recognize the stranger outside. 'Yes', I said ....'Can you help me, Ma'am?.....I have run out of gas just below the hill in front of your house, do you have a gas can with enough gas to get me to a station? ' I think so', I responded without hesitation. 'Go around to my garage door, I will open it. There should be a gas can next to the lawn mower' There was a can with enough gasoline to send him on his way. Within 10 minutes he returned. ' Thank you, ma'am, I appreciate your hospilallity, I have knocked on four doors, no one would answer, so I appreciate your help......I can bring you some money tomorrow'. 'Never mind, ...I am happy to help you'. He was very appreciative & cast blessings upon me. I think it is a wonderful feeling to be able to help someone in need, even tho it is kind of scary during the onset. I always remember the phrase: Fear knocked at the door, Faith answered, 'and no one was there'.
