Missed Opportunity

A couple of nights ago, Michael and I were at WalMart late in the evening. We were buying a lot of frozen foods and Michael had already expressed concern about our food melting. We attempted to choose the best line to check-out from. We got in a short line, behind a man and his teenage daughter. When they got to the cashier and tried to pay, it didn't work. He was trying to pay with food stamps and his card was not working. We stood there for at least 10 minutes. The thoughts going through my mind were: man, I'm blessed...our food is melting...we chose the wrong line...poor guy...there's about a dozen people in line now. Never did I think to pay for this man's food. Michael was there as well and it didn't hit him that we should have paid until we were in the car. We felt horrible! Michael and I are so blessed and I just stood there with credit card in hand while this man and his daughter were turned away. In Matthew 25, we are told to feed the hungry and give drink to the thirsty. Am I so caught up in myself that I can't have my heart moved to help someone in need? Michael and I have been touched and we are actively seeking those strangers that are in need. Maybe we can make up our missed opportunity one day soon.
