A good tree cannot produce bad fruit, and a bad tree cannot produce good fruit. You can tell what a tree is like by the fruit it produces. You cannot pick figs or grapes from thornbushes. Good people do good things because of the good in their hearts. Bad people do bad things because of the evil in their hearts. Your words show what is in your heart. (Contemporary English Version)
I always find public confessions on TV to be something rather disingenuous. Typically, celebrity apologies only take shape when one has been caught saying something and are called on the carpet. Then, when the apology comes, it is predictably odd and incongruent, in which the person says something to the tune of, “I’m sorry if I hurt anybody by what I said. Saying that really wasn’t me. I’m not really like that.”
Well, apparently you are like that because it came out of your mouth. Jesus said that out of the overflow of the heart the mouth speaks. The words we say out loud betray what is truly inside us.
To illustrate that point, Jesus used the metaphor of a tree. If the roots, the trunk, and the branches are good and healthy, then you can be sure the tree will produce good healthy fruit. However, if the tree is diseased, or infested with insects and rotting from the inside out, then no one can expect anything other than bad fruit, not fit to consume.
If the fruit is bad, the tree is bad. If the words are hateful, sarcastic, passive-aggressive, manipulative, conniving, racist, hurtful, ignorant, mean, unjust, foolish, and either subtly or overtly abusive, then the person has a dark heart and is need of redemption, not excuses.
Conversely, if the words are affirming, encouraging, loving, compassionate, gentle, caring, direct, helpful, peaceful, kind, giving hope and life, then there is a good heart behind it.
Yes, bad hearts can parrot good words. However, those words are not genuine but mere rote recitations to achieve some sort of personal agenda. And, of course, good people will occasionally say dumb or hurtful words. In such times, let it be a reminder that we all have some shadowy places within our hearts – and that we must depend on God’s grace to enlighten those dark spaces.
It is best to observe patterns rather than focus on isolated events where either good or bad words were said. A consistent pattern of invalidating another’s experiences or feelings; intimidating or threatening others; dismissing or discounting someone’s input; or being unnecessarily blunt are all major red flags pointing to a severe heart issue.
Evil does exist in the world. And if we are not vigilant to it’s insidious role in the crafting of words, wickedness can easily smack us upside the head when we aren’t looking.

The heart cannot be concealed forever. Eventually, the virtuous person will be shown as such by their stream of speech which pours forth from the heart, as if it were living water for others to drink and enjoy. Their words reflect their good character.
The wicked person, however, cannot keep the bad words down. Those vile words sit in the soul, poisoning and making the person ill. Then, all of a sudden, the evil words come up and out with a great vomitous heave and spew impurity and unholiness all over the innocent. Their words betray their foolish and poor character.
Every tree that does not bear good fruit will be cut down and thrown into the fire. The wicked heart will not be able to speak ill of others with impunity forever. They will be called to account for their abusive words, whether overtly violent, or subtly undermining.
The righteous heart, however, shall experience divine pleasure and reward, as if the careful construction of helpful and building up words win first-prize at the great heavenly fair.
The good person loves and does not hate. They are so far from harming anyone that they even pray and wish well for their enemies. They pray for blessings on those who curse them. There is an honest striving to speak good words to everyone, regardless of who they are.
The upright heart thinks the best of everyone and holds nothing over someone else’s head. Such a good heart condemns no one, leaving all judgment to God alone. It is patient with the most exasperating of people, praying they might come to their senses and become spiritually healthy.
The righteous are able to use their speech to admonish their neighbor with care and affection. They freely forgive, happily give, liberally encourage, and use their tongue to speak words of life. Indeed, their speech is wise, humble, full of grace, and above all, loving.
If there is a problem with words, it will not do to simply change the speech. That’s because it is a heart issue. And the heart must be willing to change and be transformed by sheer mercy. Fortunately, God is the expert on renovating dilapidated hearts and performing effective heart transplants.
Jesus is the gracious carpenter. God is the divine surgeon. The Holy Spirit is the energetic power source. They are ready for the work. Will you let them in?
Almighty God, to you all hearts are open, all desires known, and from you no secrets are hid: Cleanse the thoughts of our hearts by the inspiration of your Holy Spirit so that we may perfectly love you, and worthily magnify your holy Name; through Christ our Lord. Amen.
