Feeling gratitude and not expressing it is like wrapping a present and not giving it. (William Arthur Ward, late prolific inspirational writer)
When someone treats us well or gives us a gift, we most often feel grateful and appreciative for the kindness of the donor. But, too many times, we fail to express our thanks promptly—and then, we forget about it. As Ward suggests, the initial thought of gratitude is not enough. For our own good and the pleasure of the donor, we need to express our appreciation soon.
You must show your appreciation to all who serve so well. (1 Corinthians 16:18)
