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 founded on the rock.[a] 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 fell.[b] And the ruin of that house was great.”
What is a foundation?
