Like the builders of these houses on the rock, said Jesus, is he who shall receive the words that I have spoken to you, and make them the foundation of his character and life. Centuries before, the prophet Isaiah had written, "The word of our God shall stand forever" (Isaiah 40:8); and Peter, long after the Sermon on the Mount was given, quoting these words of Isaiah added, "This is the word which by the gospel is preached unto you" (1 Peter 1:25). The word of God is the only steadfast thing our world knows. It is the sure foundation. "Heaven and earth shall pass away," said Jesus, "but My words shall not pass away." Matthew 24:35.

Den, der vil tage imod de ord, jeg har talt til jer. sagde Jesus, og gøre dem til grundvold for sin karakter og sit liv, ligner dem, der byggede disse huse på klippen. Århundreder i forvejen havde profeten Esajas skrevet: »Vor Guds ord bliver evindelig;« og da Peter, længe efter at bjergprædikenen blev holdt, anførte disse ord af Esajas, tilføjede han: »Og dette er det ord, der er blevet forkyndt jer i evangeliet.« Guds ord er det eneste urokkelige, som denne verden kender. Det er den sikre grundvold. »Himmelen og jorden skal forgå,« sagde Jesus, »men mine ord skal ingenlunde for gå.« (Es. 40,8; 1Pet. 1,25; Matt. 24,35.)
