For in every age of man, it is Christ who is awakening in him the hunger and thirst after righteousness, and then satisfying it with the only thing which can satisfy them, namely, his most blessed self. Yes, believe it. It is Christ in the child which makes it speak the truth; Christ in the child which makes it shrink from whatever it has been told is wrong. It is Christ in the young man, which fills him with lofty aspirations, hopes of bettering the world around him, hopes of training his soul to be all that it can be, and of putting forth all his powers in the service of Christ. It is Christ in the middle-aged man, which makes him strong in good works, labouring patiently, wisely, and sturdily; so that having drunk of the living waters himself, they may flow out of him again to others in good deeds; a fountain springing up in him to an eternal life of goodness. It is Christ in the old man, which makes him look on with calm content while his own body and mind decay, knowing that the kingdom of God cannot decay; for Christ is ruling it in righteousness; and all will be well with him, and with his children after him, and with all mankind, and all heaven and earth, if they themselves only will it, long after he has been gathered to his fathers. Yes, such a man knows in whom he has believed. He knows that the spiritual Rock has been following him through all his wanderings in this weary world; and that that Rock is Christ. He can recollect how, again and again, at his Sabbath haltings in his life's journey, it was to him in the Holy Communion as to the Israelites of old in their haltings in the wilderness, when the priests of Jehovah cried to the mystic rock, 'Flow forth, O fountain,' and the waters flowed. So can he recollect how, in Holy Communion, there flowed into his soul streams of living water, the water of life, quenching that thirst of his soul, which no created thing could slake; the water of life; of Christ's life, which is the light of men, shewing them what they ought to be and do; the life which is the light; the life which is according to the eternal and divine reason; the life of wisdom; which is the life of love; which is the life of justice; which is the life of Christ; which is the life of God. But if these things are so--and so they are, for Christ has said it, St. Paul has said it, St. John has said it--but if these things are so, will they not teach us much about Holy Communion, how we may receive it worthily, and how unworthily?
