One great Rabbi at least, Rashi, of the twelfth century, bears witness to the mind of the Jewish Church upon the significance of that mystic Rock. "Behold," so runs his interpretation, "I have established a King, Messiah, who shall be in Zion a stone of proving." Was ever prophecy more profoundly verified in event? Not for the lineal Israel only, but for Man, the King Messiah is, as ever, the Stone of either stumbling or foundation. He is, as ever, "a Sign spoken against." He is, as ever, the Rock of Ages, where the believing sinner hides, and rests, and builds, "Below the storm-mark of the sky, Above the flood-mark of the deep." Have we known what it is to stumble over Him? "We will not have this Man to reign over us"; "We were never in bondage to any man; who is He that He should set us free?" And are we now lifted by a Hand of omnipotent kindness to a place deep in His clefts, safe on His summit, "knowing nothing" for the peace of conscience, the satisfaction of thought, the liberation of the will, the abolition of death, "but Jesus Christ, and Him crucified"? Then let us think with always humbled sympathy of those who, for whatever reason, still "forsake their own mercy" (Jonah ii. 8). And let us inform them where we are, and how we are here, and that "the ground is good." And for ourselves, that we may do this the better, let us often read again the simple, strong assurance which closes this chapter of mysteries; "_He who confides in Him shall not be put to shame_"; "_shall not be disappointed_"; "_shall not_" in the vivid phrase of the Hebrew itself, "_make haste_." No, we shall not "make haste." From that safe Place no hurried retreat shall ever need to be beaten. That Fortress cannot be stormed; it cannot be surprised; it cannot crumble. For "IT is HE"; the Son, the Lamb, of God; the sinner's everlasting Righteousness, the believer's unfailing Source of peace, of purity, and of power. DETACHED NOTE TO IX. 5.
