Every tree is known by its own fruit. It is not from thorns that men gather figs, nor from the bramble that they can get a bunch of grapes.
A good man from the good stored up in his heart brings out what is good; and an evil man from the evil stored up brings out what is evil; for from the overflow of his heart his mouth speaks.
"And why do you all call me `Master, Master' and yet not do what I tell you?
Every one who comes to me and listens to my words and puts them in practice, I will show you whom he is like.
He is like a man building a house, who digs and goes deep, and lays the foundation on the rock; and when a flood comes, the torrent bursts upon that house, but is unable to shake it, because it is securely built.
But he who has heard and not practised is like a man who has built a house upon the soft soil without a foundation, against which the torrent bursts, and immediately it collapses, and terrible is the wreck and ruin of that house."
