There is a time honored story about a pastor who was supposedly a great lover of children. One day he looked at the sidewalk leading up to his house that had been freshly poured. Some youngsters were playing in it and leaving footprints in the fresh cement. He rushed out and yelled at the children. 

Someone said to him; "Well pastor, we thought you liked children."

He said, "Yes, I love them in the abstract but not in the concrete." 

The world is looking for concrete demonstrations of Christian love in action.
