Not long ago a couple visited us in Georgia from their home in California, and during their visit here she drove by herself to visit a friend in Atlanta, about an hour and a half away. Toward the end of the day, she called her husband from the car to report that her arrival might be later than she'd planned. He asked her to read some road signs as she passed them, so he and I could get an idea of where she was. She was in Alabama—entirely the wrong state—and was steadily moving away from us.
Her husband and I were puzzled, since she had a GPS device (global positioning system, such as Garmin) guiding her. So he asked her, "What address did you punch into the GPS?"
"I did what I always do," she said. "I pushed the button that said 'Go Home.'"
She had forgotten, however, that "Home" was California, so she had begun a three-day journey across the country.
It's important that we know exactly where we are and where we're going, or we will not arrive where we want to be. If we don't include Real Love in the destination—and use it to guide us along our way—we are certain to become lost, alone, and unhappy. If, on the other hand, we do punch "Real Love" into the destination on our "GPS," we cannot fail, regardless of the difficulties and detours we inevitably encounter.
