Unshaken or Total Ruin

Luke 6:46-49
46 “But why do you call Me ‘Lord, Lord,’ and not do the things which I say? 47 Whoever comes to Me, and hears My sayings and does them, I will show you whom he is like: 48 He is like a man building a house, who dug deep and laid the foundation on the rock. And when the flood arose, the stream beat vehemently against that house, and could not shake it, for it was [j]founded on the rock. 49 But he who heard and did nothing is like a man who built a house on the earth without a foundation, against which the stream beat vehemently; and immediately it [k]fell. And the ruin of that house was great.”
