Picture the scene to yourselves—the white-robed priests toiling up the pathway, the crowd in the court, the sparkling water poured out with choral song. And then, as the priests stood with their empty vases, there was a little stir in the crowd, and a Man who had been standing watching, lifted up a loud voice and cried, 'If any man thirst, let him come unto _Me_, and drink.' Strange words to say, anywhere and anywhen, daring words to say there in the Temple court! For there and then they could mean nothing less than Christ's laying His hand on that old miracle, which was pointed to by the rite, when the rock yielded the water, and asserting that all which it did and typified was repeated, fulfilled, and transcended in Himself, and that not for a handful of nomads in the wilderness, but for all the world, in all its generations. So here is one more instance to add to those to which I have directed your attention on former occasions, in which, in this Gospel, we find Christ claiming to be the fulfilment of incidents and events in that ancient covenant, Jacob's ladder, the brazen serpent, the manna, and now the rock that yielded the water. He says of them all that they are the shadow, and the substance is in Him. I. So then, we have to look, first, at Christ's view of humanity as set forth here. You remember the story of how the people in the wilderness, distressed by that most imperative of all physical cravings, thirst, turned upon Moses and Aaron and said, 'Why have ye brought us here to die in the wilderness, where there are neither vines nor pomegranates,' but a land of thirst and death? Just as Christ, in the former instances to which we have already referred, selected and pointed to the poisoned and serpent-stricken camp as an emblem of humanity, and just as He pointed to the hunger of the men that were starving there, as an emblem, go here He says: 'That is the world—a congregation of thirsty men raging in their pangs, and not knowing where to find solace or slaking for their thirst.' I do not need to go over all the dominant desires that surge up in men's souls, the mind craving for knowledge, the heart calling out for love, the whole nature feeling blindly and often desperately after something external to itself, which it can grasp, and in which it can feel satisfied. You know them; we all know them. Like some plant growing in a cellar, and with feeble and blanched tendrils feeling towards the light which is so far away, every man carries about within himself a whole host of longing desires, which need to find something round which they may twine, and in which they can be at rest.
