The story is told of a child psychologist who spent many hours constructing a new driveway at his home. Just after he smoothed the surface of the freshly poured concrete, his small children chased a ball across the driveway, leaving deep footprints. The man yelled after them with a torrent of angry words. His shocked wife said, "You're a psychologist who's supposed to love children." The fuming man shouted, "I love children in the abstract, not in the concrete!"

I chuckled at the alleged incident and groaned at the play on words, but the story rang true for me. While I agree in principle with the concept of self-giving love, I find myself failing to express it to the people I live and work with each day.

First Corinthians 13 describes Christian love in terms of its tangible expression: "Love suffers long and is kind; love does not envy; love does not parade itself, is not puffed up; does not behave rudely, does not seek its own, is not provoked, thinks no evil" (vv.4-5).

As a theory, love isn't worth much; as a practice, it is the world's greatest treasure. When footprints are in the driveway, people discover whether our love exists in the abstract or in the concrete.  — David C. McCasland
