Out of the abundance of the heart, the mouth speaks

If forgiveness resides in our heart, we can then speak and act on that forgiveness.

Today we will be looking at the topic of forgiveness, and how it relates to the condition of our heart. If forgiveness resides in our heart, we can then speak and act on that forgiveness. However, if what we say is unforgiving, then the words we speak illustrate or reveal what is actually in our hearts.

Luke 6:45 – The good man out of the good treasure of his heart brings out that which is good, and the evil man out of the evil treasure of his heart brings out that which is evil, for out of the abundance of the heart, his mouth speaks.

I knew a man who was recently honored at his work for being an outstanding performer, always receiving gracious comments from customers with whom he interacted on a regular basis. He even received national recognition and many accolades from his company for his achievements. However, when a particular crisis arose and he was challenged by his boss with a sharp disagreement over his mishandling of a particular situation, what began as a discussion of strategy degraded into a string of profanity and lashing out. He ended up blaming a customer for what was in reality his own inability to bring a situation to its proper conclusion. This indignation, it would seem, was always simmering and bubbling under the surface of the polished outward appearance of his performance. When a situation challenged his work, what was truly in his heart boiled over and out of his mouth, revealing the true nature of his character.

Yeshua calls this the “fruit of the tree.” The wider context of our verse today demonstrates this idea.

Luke 6:43-45 – For there is no good tree that brings forth rotten fruit; nor again a rotten tree that brings forth good fruit. For each tree is known by its own fruit. For people don’t gather figs from thorns, nor do they gather grapes from a bramble bush. The good man out of the good treasure of his heart brings out that which is good, and the evil man out of the evil treasure of his heart brings out that which is evil, for out of the abundance of the heart, his mouth speaks.

If, as Yeshua teaches, “each tree is known by its own fruit,” then we can ascertain very quickly what is in a person’s heart by what they say, how they say it, and what they do. What we say is important, because our speech is what makes the contents of our heart known to others; it is the authorized (by us) commentary on what is in our heart.

Proverbs 10:20 – The tongue of the righteous is pure silver; the heart of the wicked is of little value.

Notice how the tongue of the righteous is contrasted with the heart of the wicked. By locking these two themes together, Solomon is passing commentary on how the tongue (that is, what we say) and the heart are absolutely connected.

In a heated discussion with the Pharisees, Yeshua says the following:

Matthew 12:34-37 – “Brood of vipers! How can you speak good things when you are evil? For the mouth speaks from the overflow of the heart. A good person produces good things from his storeroom of good, and an evil person produces evil things from his storeroom of evil. I tell you that on the day of judgment people will have to account for every careless word they speak. For by your words you will be acquitted, and by your words you will be condemned.”

Yeshua teaches that the heart is like a storeroom where either good things exist, or where evil things exist. The underlying Greek term is where we get our word thesaurus from. Consider what a thesaurus is: a thesaurus is a storehouse of words that have similar meanings. Our heart is a storehouse where similar things are stored, either good or bad. It implies a wealth, abundance, or treasure; either a treasure of positive, helpful things or an abundance of unhelpful and wicked things. We make deposits in our hearts with every thought, every interaction, and every distraction. Based on what we allow ourselves to be engaged with every day, it is up to us if those things that we are storing up are good or evil. Either way, Yeshua teaches that the mouth speaks from the overflow of the heart, so whatever we have stored up in our heart is what is going to come out at some point.

According to the logic Yeshua uses here, the words we say are evidence that can be used in our favor, or against us. This is the same principle today used in courtrooms to determine the guilt or innocence of individuals. How many times on a courtroom drama on TV or a courtroom scene in a movie have you seen the story lead up to a climax when an individual becomes trapped in the witness stand being confronted with information that varies from what they are testifying under oath?

This is the same type of process that goes on in people’s minds when we are interacting with each other. We all pass judgment on others, not necessarily to be overly critical, but to gauge the sincerity of an individual to see if their words line up with their actions. When they do, we consider that individual trustworthy; when they don’t, we de-value what that person says because they are inconsistent and therefore unreliable. In essence, we are conducting “fruit inspections” as part of our normal course of interacting in a society of individuals.

Looking at these passages, we can see how Yeshua is teaching that the heart is the driver of what we say and do. If our speech and actions are not where they need to be, we may be in need of some work on our hearts.

This is where things can get challenging.

Jeremiah 17:9-10 – The heart is more deceitful than anything else, frail and weak ​– ​who can understand it?  I, Yahweh, examine the mind, I test the heart to give to each according to his way, according to what his actions deserve.

Notice how Yahweh lets us know that the difficulty we face when we explore our own hearts is that we can easily be deceived when doing so. It’s like being dropped into a dark cavern without a map and being expected to know where every winding passage leads. The light from our headlamp only shines for a limited way in front of us. From time to time, the cavern walls crumble with the threat of cave-in due to the frailty and weakness of the structure. We may travel for hundreds of yards down  a passage only to reach a dead end.

Additionally, we have difficulty being objective when we explore our hearts because we are intimately and inextricably emotionally tied to outcomes that are based on our heart motives which can be weak and unsupported. When we discover long-standing perspectives that may be unfounded or not as we expected, we can become disoriented and lose our way within the emptiness of failed ambitions or missed opportunities.

But the good news, according to Jeremiah, is that Yahweh also says that he understands our heart by searching out its depths, and testing and trying the mind. He provides everyone according to their way, “according to what their actions deserve.” In this type of biblical karma, God is providing an experience for each person based on what actions are being driven by the heart’s disposition.

If this is the case for all of humanity, then it is in our best interest to look to Yahweh as the Creator of all to understand the true condition of our heart.  This is not something we should attempt on our own due to the potential dangers we just discussed. If the heart that we have is so frail and deceptive, how can we control what comes out of its overflow in our speech and actions? How can we fill our hearts with love and forgiveness that is necessary to engage with others in ways that our Creator desires?

In a moment, we will see how God has provided a solution to the challenges we face in the wayward directions of our hearts. He himself can provide the motivation and strength that is so critical to living a life that has real and demonstrable love for others.   

If we revisit what Yeshua taught in relation to our hearts, that we speak comes out of the overflow of whatever good or evil is stored up in the heart, then it is in our best interest to know how to ensure that we have only good in our hearts. However, from what we have learned so far, the heart is frail and can be deceptive even to our own reasonings.

There was a promise made to ancient Israel that we can look to to help us understand how God views the situation. Israel had become corrupt before God, and because they refused to listen to his instruction, they were removed from the land he had promised to them and they were spread among the nations as a punishment for their disobedience. Yet, God reveals this happened as a way of teaching them that they would need to rely on him, not their own strength and reasoning, to accomplish his Word.

Ezekiel 36:23-28 – “I will honor the holiness of my great name, which has been profaned among the nations ​– ​the name you have profaned among them. The nations will know that I am Yahweh ​– ​this is the declaration of Yahweh GOD ​– ​when I demonstrate my holiness through you in their sight.  For I will take you from the nations and gather you from all the countries, and will bring you into your own land. I will also sprinkle clean water on you, and you will be clean. I will cleanse you from all your impurities and all your idols. I will give you a new heart and put a new spirit within you; I will remove your heart of stone and give you a heart of flesh. I will place my Spirit within you and cause you to follow my statutes and carefully observe my ordinances. You will live in the land that I gave your fathers; you will be my people, and I will be your God.

This is an amazing passage that provides us some critical information in the discussion of the heart. Yahweh said in order for Israel to be the light to the nations that they were destined to be, he would need to not just renovate or repair but to replace their collective heart with a new one. This new heart would provide the motivation and strength, guided by his own Spirit, to actually follow his statutes and ordinances, as he had originally intended for them.

This same thing is also mentioned in the famous passage in Jeremiah:

Jeremiah 31:31-34 – “Look, the days are coming” ​– ​this is Yahweh’s declaration ​– ​”when I will make a new covenant with the house of Israel and with the house of Judah. “This one will not be like the covenant I made with their ancestors on the day I took them by the hand to lead them out of the land of Egypt ​– ​my covenant that they broke even though I am their master” ​– ​Yahweh’s declaration. “Instead, this is the covenant I will make with the house of Israel after those days” ​– ​Yahweh’s declaration. “I will put my teaching within them and write it on their hearts. I will be their God, and they will be my people. “No longer will one teach his neighbor or his brother, saying, ‘Know Yahweh,’ for they will all know me, from the least to the greatest of them” ​– ​this is Yahweh’s declaration. “For I will forgive their iniquity and never again remember their sin.

This teaching that would be in their hearts would be placed there by God himself. He would provide them the new hearts of obedience that would accomplish his purpose in the world. Ezekiel relates that the nations would come to know Yahweh when they saw him demonstrate his holiness through them by restoring them to himself, even though they had strayed so far from him.

When Yeshua arrived to instruct the nation one last time before they would disappear from the world stage, he pronounced the same message to Nicodemus, a leader in Israel, this message previously revealed by Jeremiah and Ezekiel.

John 3:3-8 – Yeshua replied, “Truly I tell you, unless someone is born again, he cannot see the kingdom of God.”  “How can anyone be born when he is old? ” Nicodemus asked him. “Can he enter his mother’s womb a second time and be born? ”  Yeshua answered, “Truly I tell you, unless someone is born of water and the Spirit, he cannot enter the kingdom of God. Whatever is born of the flesh is flesh, and whatever is born of the Spirit is spirit. Do not be amazed that I told you that you must be born again. The wind blows where it pleases, and you hear its sound, but you don’t know where it comes from or where it is going. So it is with everyone born of the Spirit.”

To be born of the Spirit of God was another way of saying they needed to have a new heart. This was the only way for Israel to have the contents of their hearts switched from evil to good. God was doing a work with the remnant of his people who would hear this message of the kingdom to become the born-again people of the new covenant and the new Creation. In doing this work in their lives, God would be demonstrating his holiness among his own people, and through this faithfulness those from among the nations would be drawn to Yahweh, as well.

Romans 15:8-12 – For I say that Messiah became a servant of the circumcised on behalf of God’s truth, to confirm the promises to the fathers, and so that Gentiles may glorify God for his mercy. As it is written, Therefore I will praise you among the Gentiles, and I will sing praise to your name.  Again it says, Rejoice, you Gentiles, with his people! And again, Praise Yahweh, all you Gentiles; let all the peoples praise him!  And again, Isaiah says, The root of Jesse will appear, the one who rises to rule the Gentiles; the Gentiles will hope in him.

God knew all along that once he chose Israel, they would fall away and he would have to scatter them throughout the known world. But this was also with the understanding that in drawing them back to himself through Messiah, others from among the nations would also be drawn to him. This was and is the method that God has set in place to draw all people to himself through Messiah Yeshua. God has demonstrated himself faithful with Israel, thereby providing a firm foundation for those of other nations to come to him, as well.

If we are to be speaking and demonstrating forgiveness and reconciliation with others, then that forgiveness and reconciliation will truly need to be in our heart. This can only be accomplished when we step out of the way of our old natures and allow God to work through our renewed nature in those situations.

2 Corinthians 5:16-19 – Therefore we know no one after the flesh from now on. Even though we have known Messiah after the flesh, yet now we know him so no more. Therefore if anyone is in Messiah, he is a new creation. The old things have passed away. Behold, all things have become new. But all things are of God, who reconciled us to himself through Yeshua Messiah, and gave to us the ministry of reconciliation; that is, in Messiah, God was reconciling the world to himself, not counting their trespasses against them, and he has committed the message of reconciliation to us.

As this message of reconciliation spreads, more and more people have their hearts changed out to become hearts of obedience guided by the Spirit of God. That’s the good news of the kingdom. The even better news is that, knowing we still have the capability to slip and fall accidentally from time to time, we still retain the ability to ask for ongoing renewal when we mess up.

1 John 1:6, 9 – If we say, “We have fellowship with him,” and yet we walk in darkness, we are lying and are not practicing the truth. … If we confess our sins, he is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness.

If, as Paul writes, we are new creations, then we need to operate within the new Creation of God’s kingdom, and live and abide by its principles, not the principles of this old Creation. Both Yeshua and Paul convey that the principle of reconciliation and forgiveness is a core principle of God’s kingdom. If our hearts have been renewed, then that forgiveness and reconciliation can truly reside in our new hearts. What we place in our heart from that time on is up to us.

Our ability to speak this forgiveness and reconciliation to those around us appears to be a choice that we have every day, but only when we recognize and remember who we really are. It is in this fashion that God is honored among the nations when his children are operating with the righteousness of his kingdom regardless of the outward situations and conditions they encounter. When the abundance of the heart is good treasure, then that good treasure can’t help but be shared with those who need it most.
