A good tree produces good fruit, and a bad tree produces bad fruit. You can tell what a tree is like by the fruit it produces. You are a bunch of evil snakes, so how can you say anything good? Your words show what is in your hearts. Good people bring good things out of their hearts, but evil people bring evil things out of their hearts. I promise you on the day of judgment, everyone will have to account for every careless word they have spoken. On that day they will be told they are either innocent or guilty because of the things they have said. (Contemporary English Version)
Words are important. They have meaning and power.
Our speech is the outward demonstration of what is really within the heart. There really isn’t any room to believe that a constant stream of gossip, backbiting, slander, and negative comments is anything but coming from a heart of evil. The person who speaks such words is not a loving, gracious, merciful person. Conversely, the person who continually encourages, uplifts, and seeks to be positive, reflects a deep heart of love for others.
Therefore, simply altering our speech when we’re around particular people is not the point; and it does no good. That kind of talking only breeds hypocrisy and is two-faced. Instead, the place to aim is the heart because that’s where the words come from. And the way to truly renovate a heart is to sub-contract the project to Jesus.
The people we typically hang-out with the most are the people that most influence our attitudes and our speech.
So, if we spend copious amounts of time with Jesus, it’s inevitable that our hearts will become more like his heart, and thus, our words will be in alignment with the words and ways of Christ. Be rooted in Christ and the fruit of the tree will demonstrate it.
I always find public confessions on TV to be a rather disingenuous affair. 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’s predictably odd and incongruent, with the person saying 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. 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.
Jesus used the metaphor of a tree to illustrate his point. 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.
Let’s observe patterns, rather than focusing 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 exists in the world. And if we are not vigilant to the power of language, 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 the stream of gracious 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 wins 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.
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.
