The houses built by the two men in the parable were exactly alike. They had the same walls, the same kind of roof, the same doors, and the same windows; but when the storm was over, one was a heap of rubbish, and the other stood just as it was before the storm. The difference was due to the fact that one was built on sand and the other on the rock. Such, Christ said, is the difference between the man who hears and obeys and believes his words, and the one who does not.
Dr. Thomas Chalmers who matriculated at the age of 12, was a Divinity student at 15, and was licensed to preach at 19, was called to the Parish of Kilmany in Scotland. Of himself at that time he wrote, `I could expatiate only on the meanness of dishonesty, on the villainy of falsehood, on the despicable arts of calumny, in a word, upon all those deformities of character which awaken the natural indignation of the human heart.' Now and again he denounced the designs of Napoleon Bonaparte. In May 1811 Chalmers wrote in his journal, 'I am much taken with Walker's observation that we are commanded to believe on the Son of God.' Then he stepped from the treacherous ground of 'Do and Live' to place his feet on the firm foundation of 'Believe on the Lord Jesus Christ and thou shalt be saved.'—Dr. F. W. Boreham
