Christ the One Foundation.
Let us consider a few of the senses in which Christ makes good this title of corner-stone.
I. How, do we think, did the first preachers to the heathen win converts? By appealing to men's deepest sense of need, to the felt necessity of a centralising, consolidating principle of human life. Two things, at least, we must secure if life is not to be a failure. (1) One is something certainly true, a truth to stand by amid uncertainties. As we advance in our earthly journey, perplexities gather round on all sides; life has not verified our first expectations; it raises questions which it does not answer; there is a confusion and discord of theories, but where is that which we can depend upon and grasp firmly, looking life and death in the face? The answer is in the words of Jesus, "I am the Truth." (2) Again, man needs a power of moral and spiritual rectification. He wants to be cleansed from his own unholiness, relieved of his own sense of guilt, otherwise he cannot build in peace; how should he? Life, to be worth having, must be a life with a quiet conscience. To believers in Christ He is all-precious, because He can and does help them to become pure and single-hearted, high in aim and active in duty.
II. In His relation to the several doctrines and institutions of His kingdom, Christ sustains the character of the one foundation. (1) It is so in regard to doctrines; He is the one object whom they set before us. (2) He is also the foundation of all His ordinances. (3) If Christ be in these ways the foundation of our spiritual life in all its aspects, should He not be also the foundation of all that we do? Let us "consider our ways," and resume the building of the spiritual house within us, being assured that the promise will be abundantly verified to us, "Be strong, and work, for I am with you."
