'Therefore, whosoever heareth these sayings of Mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock.... 25. And every one that heareth these sayings of Mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand.'--Matt. vii. 24, 25.
Our Lord closes the so-called Sermon on the Mount, which is really the King's proclamation of the law of His Kingdom, with three pairs of contrasts, all meant to sway us to obedience. The first is that of the two ways: one broad, and leading down to abysses of destruction; the other narrow, and leading up to shining heights of life. The second is that of the two trees, one good and one bad, each bearing fruit according to its nature; by which our Lord would teach us that conduct is the outcome and revelation of character, and the test of being a follower of His. The third is that of our text, the two houses on the two foundations, and their fate before the one storm; by which our Lord would teach us that the only foundation on which can be built a life that will stand the blast of final judgment is His sayings and Himself.
Now, there are many very important and profound links of connection and relation between these three contrasted pictures, but I only point to one thing here, and that is that in all of them Jesus Christ most decisively divides all His hearers--for it is about them that He is speaking--into two classes: either on the broad road or on the narrow, not a foot in each; either the good tree or the bad; either the house on the sand or the house on the rock. Such a sharp division is said nowadays to be narrow, and to be contradicted by the facts of life, in which the great mass of men are neither very white nor very black, but a kind of neutral grey. Yes, they are--on the surface. But if you go down to the bottom, and grasp the life in its inmost principles and essential nature, I fancy that Jesus Christ's narrowness is true to fact. At all events, there it is.
Now, following out the imagery of our text, I wish to bring before you the two foundations, the two houses, the one storm, the two endings.
I. The two foundations: Rock, Sand.
Now, to build on the Rock, Jesus Christ Himself explains to us as being the same thing as to hear and do His sayings. The one representation is plain fact, the other is metaphor which points precisely in the same direction. It is scarcely a digression if I pause for a moment, and point you to the singular and unique attitude which this Carpenter's Son of Nazareth takes up here, fronting the whole race with that 'whosoever,' and alleging that _His_ sayings are an infallible law for conduct, and that _He_ has the right absolutely to command every man, woman, and child of the sons and daughters of Adam. And the strange thing is that the best men have admitted His claim, have recognised that He had the right, and have seen that His precepts are the very ideal of human conduct, and, if they have ventured to criticise at all, their criticism has only been that the precepts are too good to be obeyed, and contemplate an ideal that is unreachable in human society. Be that as it may, there stands the fact that this Man, in this Sermon on the Mount, which so many people say has no doctrinal teaching in it, assumes an attitude which nothing can warrant and nothing explain except the full-toned belief that in Him we have God manifest in the flesh.
But what I desire to point to now is the significance of this demand that He makes, that we shall take His sayings as the foundation of our lives. The metaphor is a very plain one, by which the principles that underlie or dominate and mould our conduct are regarded as the foundation upon which we build the structure of our lives. But the Sermon on the Mount is not all of these 'sayings of Mine.' It is fashionable in certain quarters to-day to isolate these precepts, and to regard them as being the part of Christian Revelation by which men who set little store by theological subtleties, and reject the mysteries of the Incarnation and the Atonement, may still abide. But I would have you notice that it is absurd to isolate this Sermon on the Mount, or to deal with it as if it were the very centre of the Christian Revelation. It is nothing of the sort. Beautiful as it is, wonderful as it is as a high ideal of human conduct, it is a law still, though it is a perfect law; and it has all the impotences and all the deficiencies that attach to a law, if you take it and rend it out of its place, and insist upon dealing with it as if it stood alone. There is not a word in it that tells you how to keep its precepts. There is no power in it, or raying from it, to make a man obey any one of its commandments. It comes radiant and beautiful, but imperative, and just because no man keeps it to the full, its very beauty becomes menacing, and it stands there over against us, showing us what we ought to be, and, by consequence, what we are not. And is that all that Jesus Christ came into the world to do? God forbid! If He had only spoken this Sermon on the Mount--which some of you take for the _Alpha_ and the _Omega_ of Christianity as far as you are concerned--He would not have been different in essence from other teachers,--though high above them in degree,--who speak to us of the shining heights of duty that we are to scale, but leave us grovelling in the mire.
