Alas for many hearers of the Word! Alas for many admirers of the "Sermon on the Mount"! Where will they be when everything turns on the question "Wert thou a doer of it?" [5] It is true that under the head of oaths comes the duty of reverence, which scarcely seems to fall under this head; but it will be remembered that this point comes in by way of a very natural suggestion in dealing with falsehood and the regulation of conversation, which evidently belongs to righteousness as between man and man. [6] This complete change of meaning, amounting in fact to the destruction and almost to the inversion of the sense, is one of many illustrations of the absolute need of revision from time to time of translations, not only to make them more correct, but even to keep them as correct as they were at first. [7] Duty of course in its largest sense--to God and man and self--including all "righteousness" in the Master's sense of the word. VIII. _THE SIGNS OF THE KINGDOM._ MATT. viii.-ix. 35. Referring to chapter iv. 23, we find the work of Christ at the beginning of His ministry summarised as teaching and preaching and healing all manner of diseases. Of the teaching and preaching we have had a signal illustration in what is called the Sermon on the Mount; now the other great branch of the work is set before us in a group of miracles, filling up almost the whole of the eighth and ninth chapters. The naturalness of the sequence will be at once apparent. If men had needed nothing more than counsel, guidance, rules of life, then might the Gospel have ended when the Sermon on the Mount was concluded. There are those who think they need nothing more; but if they knew themselves they would feel their need not only of the Teacher's word, but of the Healer's touch, and would hail with gladness the chapters which tell how the Saviour dealt with the poor leper, the man with the palsy, the woman with the fever, those poor creatures that were vexed with evil spirits, that dead damsel in the ruler's house. We may well rejoice that the great Teacher came down from the mountain, and made Himself known on the plain and among the city crowds as the mighty Healer; that His stern demand for perfect righteousness was so soon followed by that encouraging word, so full of comfort, for such as we: "I came not to call the righteous, but sinners" (ix. 13). The healing, then, is quite as essential as the teaching. The Sermon points out the way, unfolds the truth; but in the touch and word of the King Himself is found the life. The Christ of God had come, not as a mere Ambassador from the court of heaven to demand submission to its laws, but as a mighty Saviour, Friend, and Comforter. Hence it was necessary that He should make full proof of His mission in this respect as well as in the other; and accordingly the noble ethics taught on the mount are followed by a series of heavenly deeds of power and loving-kindness done in the plain.
