Whosoever. — The Greek is more emphatically universal, every one whosoever.
These sayings of mine. — The reference to what has gone before tends, so far as it goes, to the conclusion that we have in these Chapter s a continuous discourse, and not a compilation of fragments. On the assumption that the Sermon on the Plain was different from that on the Mount, the recurrence of the same image there makes it probable that this or some similar parable was not an uncommon close to our Lord’s discourses.
I will liken him unto a wise man. — The surrounding scenery may, in this as in other instances, have suggested the illustration. As in all hilly countries, the streams of Galilee rush down the torrent-beds during the winter and early spring, sweep all before them, overflow their banks, and leave beds of alluvial deposit on either side. When summer comes their waters fail (comp. Jeremiah 15:18; Job 6:15), and what had seemed a goodly river is then a tract covered with debris of stones and sand. A stranger coming to build might be attracted by the ready-prepared level surface of the sand. It would be easier to build there instead of working upon the hard and rugged rock. But the people of the land would know and mock the folly of such a builder, and he would pass (our Lord’s words may possibly refer to something that had actually occurred) into a by-word of reproach. On such a house the winter torrent had swept down in its fury, and the storms had raged, and then the fair fabric, on which time and money had been expended, had given way, and fallen into a heap of ruins. Interpreting the parable in the connection in which our Lord has placed it, it is clear that the house is the general fabric of an outwardly religious life. “The rock” can be nothing else than the firm foundation of repentance and obedience, the assent of the will and affections as well as of the lips. The “sand” answers to the shifting, uncertain feelings which are with some men (the “foolish” ones of the parable) the only ground on which they act — love of praise, respect for custom, and the like. The “wind,” the “rain,” the “floods” hardly admit, unless by an unreal minuteness, of individual interpretation, but represent collectively the violence of persecution, of suffering, of temptations from without, beneath which all but the life which rests on the true foundation necessarily gives way.
Such is obviously the primary meaning of the parable here, but, like most other parables, it has other meanings, which, though secondary, are yet suggestive and instructive, and are not unsanctioned by the analogy of our Lord’s teaching. (1.) Already He had bestowed upon one of His disciples the name of Cephas, Peter, the Rock, and in so doing had at least indicated the type of character represented by the “rock” upon which the wise man built. When He afterwards said, “Upon this rock will I build my Church,” He was speaking in the character of a wise Master-builder who saw in fervent faith and unhesitating obedience the ground-work on which the Christian society, which He designated as His kingdom, was to rest. (2.) Personal experience and the teaching of the Spirit led men to the thought that there must be a yet deeper foundation, a rock below the rock even of obedience and holiness; and they found in Christ Himself that Rock and that Foundation (1 Corinthians 3:10-11). Only in personal union with Him could they find the stability of will without which even their firmest purposes would be as the shifting sand.
