"Why do you see the speck that is in your brother's eye, but do not notice the log that is in your own eye? Or how can you say to your brother, 'Brother, let me take out the speck that is in your eye,' when you yourself do not see the log that is in your own eye? You hypocrite, first take the log out of your own eye, and then you will see clearly to take out the speck that is in your brother's eye.
"For no good tree bears bad fruit, nor again does a bad tree bear good fruit; for each tree is known by its own fruit. For figs are not gathered from thorns, nor are grapes picked from a bramble bush. The good man out of the good treasure of his heart produces good, and the evil man out of his evil treasure produces evil; for out of the abundance of the heart his mouth speaks.
"Why do you call me 'Lord, Lord,' and not do what I tell you? Every one who comes to me and hears my words and does them, I will show you what he is like: he is like a man building a house, who dug deep, and laid the foundation upon rock; and when a flood arose, the stream broke against that house, and could not shake it, because it had been well built. But he who hears and does not do them is like a man who built a house on the ground without a foundation; against which the stream broke, and immediately it fell, and the ruin of that house was great."
