The scope of service is not limited to great gestures like giving big donations to public institutions. They also serve who express their love in little things. A word that gives courage to a drooping heart or a smile that brings hope and cheer in the midst of gloom has as much claim to be regarded as service as onerous sacrifices and heroic self-denials. A glance that wipes out bitterness from the heart and sets it throbbing with a new love is also service, although there may be no thought of service in it. When taken by themselves, all these things seem to be small; but life is made up of many such small things. If these small things were ignored, life would be not only unbeautiful but unspiritual.
