Thou hast given so much to me,
Give me one thing more – a grateful heart;
Not thankful when it pleaseth me,
As if Thy blessings had spare days;
But such a heart whose pulse may be
Thy praise.
~ George Herbert
Light gives of itself freely, filling all available space. It does not seek anything in return; it asks not whether you are friend or foe. It gives of itself and is not thereby diminished.
