Jesus Teaches about False Teachers

⁴³ “A good tree cannot have bad fruit. A bad tree cannot have good fruit. ⁴⁴ For every tree is known by its own fruit. Men do not gather figs from thorns. They do not gather grapes from thistles. ⁴⁵ Good comes from a good man because of the riches he has in his heart. Sin comes from a sinful man because of the sin he has in his heart. The mouth speaks of what the heart is full of.
