“Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock: 25 and the rain descended, the floods came, and the winds blew and beat on that house; and it did not fall, for it was founded on the rock.
26 “But everyone who hears these sayings of Mine, and does not do them, will be like a foolish man who built his house on the sand: 27 and the rain descended, the floods came, and the winds blew and beat on that house; and it fell. And great was its fall.”
28 And so it was, when Jesus had ended these sayings, that the people were astonished at His teaching, 29 for He taught them as one having authority, and not as the scribes.” ~ Matthew 7:24-29.
The crowds are astonished when they compare the authoritative and powerful teaching of Jesus with the weak words of the scribes.
“the rain descended” (vv.25, 27). — Storms in Palestine are infrequent but can be violent. Although the houses of the foolish and the wise may for a long time appear equally secure, when the storm comes the destruction of the foolish one’s house is total (Isaiah 28:14–18). So it is with the life of those who ignore the words of Jesus.
“not as the scribes” (v.29). — The scribes, like the later rabbis, taught by referring to what previous teachers had said. Their authority was the tradition. Jesus taught directly from Scripture with His own authority.
