The Imitation of Christ, by Thomas a Kempis, tr. by William Benham , at sacred-texts.com
O how great is the abundance of Thy sweetness, O Lord, which Thou hast laid up for them that fear Thee. When I call to mind some devout persons who draw nigh to Thy Sacrament, O Lord, with the deepest devotion and affection, then very often I am confounded in myself and blush for shame, that I approach Thine altar and table of Holy Communion so carelessly and coldly, that I remain so dry and without affection, that I am not wholly kindled with love before Thee, my God, nor so vehemently drawn and affected as many devout persons have been, who out of the very earnest desire of the Communion, and tender affection of heart, could not refrain from weeping, but as it were with mouth of heart and body alike panted inwardly after Thee, O God, O Fountain of Life, having no power to appease or satiate their hunger, save by receiving Thy Body with all joyfulness and spiritual eagerness.
2. O truly ardent faith of those, becoming a very proof of Thy Sacred Presence! For they verily know their Lord in the breaking of bread, whose heart so ardently burneth within them(1) when Jesus walketh with them by the way. Ah me! far from me for the most part is such love and devotion as this, such vehement love and ardour. Be merciful unto me, O Jesus, good, sweet, and kind, and grant unto Thy poor suppliant to feel sometimes, in Holy Communion, though it be but a little, the cordial affection of Thy love, that my faith may grow stronger, my hope in Thy goodness increase, and my charity, once kindled within me by the tasting of the heavenly manna, may never fail.
3. But Thy mercy is able even to grant me the grace which I long for, and to visit me most tenderly with the spirit of fervour when the day of Thy good pleasure shall come. For, although I burn not with desire so vehement as theirs who are specially devout towards Thee, yet, through Thy grace, I have a desire after that greatly inflamed desire, praying and desiring to be made partaker with all those who so fervently love Thee, and to be numbered among their holy company.
