But note the fact, that when Abraham built on the Lord it was counted to him for righteousness. The Lord never makes any mistakes in His reckoning. When Abraham’s faith was reckoned to him for righteousness, it was because it was indeed righteousness. How so? Why, as Abraham built on God, he built on everlasting righteousness. “He is my rock, and there is no unrighteousness in Him.” He became one with the Lord, and so God’s righteousness was his own. “The words of the Lord are pure words: as silver tried in a furnace of earth, purified seven times.” Psalms 12.6. Therefore he who builds upon the Rock Jesus Christ, by accepting His word in living faith, builds upon a tried foundation. So we read: “Wherefore laying aside all malice, and all guile, and hypocrisies, and envies, and all evil speaking, as newborn babes, desire the sincere milk of the word, that ye may grow thereby: if so be ye have tasted that the Lord is gracious. To whom coming, as unto a living stone, disallowed indeed of men, but chosen of God, and precious, ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ. Wherefore also it is contained in the Scripture, Behold, I lay in Zion a chief corner stone, elect, precious: and he that believeth on him shall not be confounded.” 1 Peter 2.1-6 The force of this is not so clearly seen until we read the passage of Scripture, which is quoted by the apostle, in connection with the one that we have quoted from the Saviour’s Sermon on the Mount. Recalling the latter, we read from the prophecy of Isaiah: - “Therefore thus saith the Lord God, Behold, I lay in Zion for a foundation a stone, a tried stone, a precious corner-stone of sure foundation: he that believeth shall not make haste. And I will make judgment the line, and righteousness the plummet: and the hail shall sweep away the refuge of lies, and the waters shall overflow the hiding place. And your covenant with death shall be disannulled, and your agreement with hell shall not stand; when the overflowing scourge shall pass through, then ye shall be trodden down by it. As often as it passeth through, it shall take you; for morning by morning shall it pass through, by day and by night: and it shall be nought but terror to understand the message.” Isaiah 28.16 Christ is the tried foundation. Righteousness is the plummet by which He is laid. His character is perfectly true and right. Satan exhausted all his arts in trying to lead Him to sin, and was unsuccessful. He is a sure foundation. We build on Him by believing His word, as He Himself said. The floods will surely come. There will be an overflowing scourge that will sweep away the refuge of lies, and all who have built on a false foundation. The house built on the sand will certainly fall. When the storm begins to beat with fury, those who have made lies their refuge will flee for their lives as their foundation begins to totter; but the flood will carry them away. This is the picture presented by the two passages of Scripture.
