Luke 6:39-45

He also told them a parable: “Can a blind man guide [another] blind man? Will they not both fall into a hole in the ground? A student is not superior to his teacher; but everyone, after he has been completely trained, will be like his teacher. Why do you look at the speck that is in your brother’s eye, but do not notice or consider the log that is in your own eye? How can you say to your brother, ‘Brother, allow me to 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 (play actor, pretender), 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 there is no good tree which produces bad fruit, nor, on the other hand, a bad tree which produces good fruit. [Matt 7:16, 18] For each tree is known and identified by its own fruit. For figs are not picked from thorn bushes, nor is a cluster of grapes picked from a briar bush. The [intrinsically] good man produces what is good and honorable and moral out of the good treasure [stored] in his heart; and the [intrinsically] evil man produces what is wicked and depraved out of the evil [in his heart]; for his mouth speaks from the overflow of his heart.
