Parable about Wise and Foolish Builders: The folly of knowledge without obedience

Luke 6:47-49

Everyone who comes to me, and hears my words, and does them, I will show you who he is like. He is like a man building a house, who dug and went deep, and laid a foundation on the rock. When a flood arose, the stream broke against that house, and could not shake it, because it was founded on the rock. But he who hears, and doesn’t do, is like a man who built a house on the earth without a foundation, against which the stream broke, and immediately it fell, and the ruin of that house was great.
