He is the foundation for all noble and pure living. He is the fixed pattern to which it may be conformed. Otherwise man's notions of what is virtuous and good are much at the mercy of conventional variations of opinion. This class, that community, this generation, that school, all differ in their notions of what is true nobleness and goodness of life. And we are left at the mercy of fluctuating standards unless we take Christ in His recorded life as the one realised ideal of manhood, the pattern of what we ought to be. We cannot find a fixed and available model for conduct anywhere so useful, so complete, so capable of application to all varieties of human life and disposition as we find in Him, who was not this man or that man, in whom the manly and the feminine, the gentle and the strong, the public and the private graces were equally developed. In Christ there is no limitation or taint. In Christ there is nothing narrow or belonging to a school. This water has no taste of any of the rocks through which it flowed. You cannot say of Jesus Christ that He is a Jew or a Gentile, that He is man or woman, that He is of the ancient age or the modern type, that He is cut after this pattern or that. All beauty and all grace are in Him, and every man finds there the example that he needs. So, as the perfect pattern, He is the foundation for all noble character. As the one sufficient motive for holy and beauteous living, He is the foundation. 'If ye love Me, keep My commandments.' That is a new thing in the world's morality, and that one motive, and that motive alone, has power, as the spring sunshine has, to draw beauty from out the little sheaths of green, and to tempt the radiance of the flowers to unfold their lustre. They that find the reason and the motive for goodness and purity in Christ's love to them, and their answering love to Christ, will build a far fairer fabric of a life than any others, let them toil at the building as they may. So, dear brethren, on this foundation God has built His mercy to all generations, and on this foundation you and I may build our safety, our love, our thinkings, our obedience, and rest secure. II. Note next the tried preciousness of the foundation. The language of the text, 'a stone of proof,' as it reads in the original, probably means a stone which has been tested and stood the trial. And because it is thus a tested stone, it therefore is a precious stone. There are two kinds of testing--the testing from the assaults of enemies, and the testing by the building upon it of friends. And both these methods of proof have been applied, and it has stood the test.
