Matthew 7:24-29 Building On The Rock.
The ‘therefore’ that begins verse 24 tells us that what Jesus is about to say follows upon what Matthew has recorded him as just saying (Cf. Lk. 6:47-49). The crux of the preceding verses (15-23), is that by one’s fruit one is known, and to be a true believer involves first being known by Jesus (v. 23). The fruit of those known is that they live according to the law. “Therefore,” Jesus says, “whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on a rock” (v. 24). A wise person is one who lives their life according to all the Scriptures – the Law, the Prophets, and the teachings of Jesus, for they are all one. However, anyone who heard what Jesus was saying, again including his teaching to live according to the Law and the Prophets (5:17-20), is like someone who builds their house on sand that gets washed away. In placing his teaching on a par with the Law and the Prophets, he showed that he spoke by his own authority, not like the scribes, and for this reason the people were also amazed (vv. 28-29 Cf. Mt. 13:34; Jn. 7:46).
