Living thus we shall make each hour radiant with the radiancy of duty well done, and radiant hours will make radiant years. But the missing of privileges and the neglecting of duties will leave days and years marred and blemished and make the life at last like a moth-eaten garment. We must catch the sacred meaning of our opportunities if we would live up to our best. CHAPTER XX. THE SIN OF INGRATITUDE. "The sun may shine upon the clod till it is warm, Warm for its own poor darkling self to live. He smites the diamond, and oh, how glows the gem, Chilling itself, irradiant, to give. "The silent soul, that takes but gives not out again, In shining thankfulness, a smile, a tear, Absorbing, makes none other glad, and misses so The purest and the best of love's rich cheer." --MARY K. A. STONE. A blessing given ought always to have some return. It is better to be a diamond, lighted to shine, than a clod, warmed to be only a dull, dark clod. We all receive numberless favors, but we do not all alike make fitting return. Krummacher has a pleasant little fable with a suggestion. When Zaccheus was old he still dwelt in Jericho, humble and pious before God and man. Every morning at sunrise he went out into the fields for a walk, and he always came back with a calm and happy mind to begin his day's work. His wife wondered where he went in his walks, but he never spoke to her of the matter. One morning she secretly followed him. He went straight to the tree from which he first saw the Lord. Hiding herself, she watched him to see what he would do. He took a pitcher, and carrying water, he poured it about the tree's roots which were getting dry in the sultry climate. He pulled up some weeds here and there. He passed his hand fondly over the old trunk. Then he looked up at the place among the branches where he had sat that day when he first saw Jesus. After this he turned away, and with a smile of gratitude went back to his home. His wife afterward referred to the matter and asked him why he took such care of the old tree. His quiet answer was, "It was that tree which brought me to him whom my soul loveth." There is no true life without its sacred memorial of special blessing or good. There is something that tells of favor, of deliverance, of help, of influence, of teaching, of great kindness. There is some spot, some quiet walk, some room, some book, some face, that always recalls sweet memories. There is something that is precious to us because in some way it marks a holy place in life's journey. Most of us understand that loving interest of Zaccheus in his old tree, and can believe the little fancy to be even true. In what life is there no place that is always kept green in memory, because there a sweet blessing was received?
