"A good tree does not bear rotten fruit, nor does a rotten tree bear good fruit. For every tree is known by its own fruit. For people do not pick figs from thornbushes, nor do they gather grapes from brambles. A good person out of the store of goodness in his heart produces good, but an evil person out of a store of evil produces evil; for from the fullness of the heart the mouth speaks. "Why do you call me, 'Lord, Lord,' but not do what I command? I will show you what someone is like who comes to me, listens to my words, and acts on them. That one is like a person building a house, who dug deeply and laid the foundation on rock; when the flood came, the river burst against that house but could not shake it because it had been well built. But the one who listens and does not act is like a person who built a house on the ground without a foundation. When the river burst against it, it collapsed at once and was completely destroyed." (Lk 6:43-49)
God called the Jews and Jesus called his disciples to produce good fruit. Every individual and the whole society are called to produce human beings. This is the true message about the trees and the fruit. Goodness of the tree or the rottenness of the tree is known from the fruit they produce. Any religion or any transformation that does not touch the heart to the individual is as good as saying that grapes are gathered from brambles.
Jesus is inviting the people for a change of heart that is a change of personality that is a change from within. Jesus does like the external changes which are cosmetics. Jesus looks for changes that are basic and fundamental. Jesus wants an attitudinal change that will affect the life and character and behaviour of the individual.
Jesus gives another stern warning and expressed this through another parable. Now he takes up the story about the foundation and the building. Listening to the true wisdom and not putting it into practice is like building without foundations. Jesus stories are so true to facts that it is applicable at anytime to anyone and anywhere.
