‘There is no sound tree that produces rotten fruit, nor again a rotten tree that produces sound fruit. Every tree can be told by its own fruit: people do not pick figs from thorns, nor gather grapes from brambles. Good people draw what is good from the store of goodness in their hearts; bad people draw what is bad from the store of badness. For the words of the mouth flow out of what fills the heart. ‘Why do you call me, “Lord, Lord” and not do what I say? ‘Everyone who comes to me and listens to my words and acts on them — I will show you what such a person is like. Such a person is like the man who, when he built a house, dug, and dug deep, and laid the foundations on rock; when the river was in flood it bore down on that house but could not shake it, it was so well built. But someone who listens and does nothing is like the man who built a house on soil, with no foundations; as soon as the river bore down on it, it collapsed; and what a ruin that house became!’
