Physiologists can tell, by studying the dentition--the system of the teeth--and the digestive apparatus of an animal, what it is meant to live upon, whether vegetables or flesh, or a mingled diet of both. And you can tell, if you will, by studying yourself, what, or whom, you are meant to live upon. The poet said, 'We live by admiration, hope, and love.' But he did not say on what these faculties, which truly nourish man's spirit, are to fix and fasten. He tells of the appetites; he does not tell of their food. My text does: 'In this mountain shall the Lord make unto all people a feast of fat things, a feast of wines on the less well refined.' Friends, look at these hearts of yours with their yearnings, with their passionate desires, with their clamant needs. Will any human love--the purest, the sweetest, the most unselfish, the most utter in its surrender--satisfy the heart-hunger of the poorest of us? No! Look at the capacities of grasping thought and truth in our spirits, which are ever seek, seek, seeking for absolutely certain foundations on which we may build the whole structure of our beliefs. You have to go deeper down than the sand of man's thinkings and teachings before you can reach what will bear without shifting the foundations of a life's credence and confidence. Look at these tumultuous wills of ours that fancy they crave to be independent, and really crave an absolute master whom it is blessedness to obey. You will find none such beneath the stars. The very elements of our being, our heart, will, mind, desires, passions, longings, all with one voice proclaim that the only food for a man is God. Jesus Christ brings the food that we need. Remember His own adaptation of this great vision of my text in more than one parable; such as the supper that was provided, and to which all men were invited, and, 'with one consent,' declined the invitation. Remember His own utterance,' I am the Bread of God which came down from heaven to give life to the world.' Remembering such words, let me plead with you to listen to the voice of warning as well as of invitation, which sounds from Cradle and Cross and Throne. 'Why will ye spend your money for that which is not bread'--you know it is not--'and your labour for that which satisfieth not?'--you know it does not. Turn to Him, 'eat, and your souls shall live.' 'In this mountain is prepared a feast... for all nations.' Notice that although it does not appear on the surface, and to English readers, this world's festival, in which every want is met, and every appetite satisfied, is a feast on a sacrifice. That touches the deepest need, about which I shall have a word or two to say presently. But in the meantime let me just press this upon you, that the Christ who died on the Cross is to be lived on by us; and that it is His sacrifice that is to be the nourishment of our spirits.
