It’s An Inside Job

43 “For no good tree bears bad fruit, nor again does a bad tree bear good fruit, 44 for each tree is known by its own fruit. For figs are not gathered from thornbushes, nor are grapes picked from a bramble bush. 45 The good person out of the good treasure of his heart produces good, and the evil person out of his evil treasure produces evil, for out of the abundance of the heart his mouth speaks.

46 “Why do you call me ‘Lord, Lord,’ and not do what I tell you? 47 Everyone who comes to me and hears my words and does them, I will show you what he is like: 48 he is like a man building a house, who dug deep and laid the foundation on the rock. And when a flood arose, the stream broke against that house and could not shake it, because it had been well built. 49 But the one who hears and does not do them is like a man who built a house on the ground without a foundation. When the stream broke against it, immediately it fell, and the ruin of that house was great.” – Luke 6:43-49 ESV

Whether they realized it or not, Jesus was presenting His disciples with a radically different standard for measuring a righteous life. Inclusion in the coming Kingdom of God was not going to be based on ethnicity or outward adherence to a set of rules and regulations. The disciples, as Jews, had grown up believing that their Hebrew lineage and their personal attempts to keep the Mosaic Law would somehow earn them entrance into the Kingdom. But as they listened to Jesus speak, it must have seemed like He was raising the bar and the entrance requirements, demanding from them a much higher standard than was humanly possible. One can almost visualize the 12 disciples glancing at one another in confusion and with growing concern as they listen to Jesus speak. All His talk of loving their enemies, suffering for His name’s sake, and removing the log from their eye must have left them scratching their heads and questioning their decision to follow Him. They had signed up to be early adopters of the Kingdom life, but now they must have been having second thoughts. And Jesus was far from done.

He follows up His parable about the blind leading the blind with another parable about two kinds of trees. But with His change of illustration, Jesus remains focused on the topic of inner transformation. For a blind man to effectively and safely lead another blind man, he will have to have his sight restored. For a disciple to become an effective teacher, he will first have to be an obedient and attentive student. He will need to internalize his teacher’s wisdom before he can impart it to others. And before a man can be qualified to point out the flaws in another, he will first need to get his own moral house in order.

Now, Jesus uses the metaphor of a fruit tree to convey the same idea of the need for inner change.

“A good tree can’t produce bad fruit, and a bad tree can’t produce good fruit.” – Luke 6:43 NLT

This simple analogy is meant to communicate a much deeper truth concerning the inseparable link between outer conduct and inner character. In his gospel account, Matthew records another occasion where Jesus used this same imagery to address the Pharisees, who had just accused Him of casting out demons by the power of Satan.

“A tree is identified by its fruit. If a tree is good, its fruit will be good. If a tree is bad, its fruit will be bad. You brood of snakes! How could evil men like you speak what is good and right? For whatever is in your heart determines what you say. A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart.” – Matthew 12:33-35 NLT

Jesus exposed these self-righteous Pharisees as “bad” trees that produced unacceptable fruit. They were incapable of producing good fruit because they had evil hearts. In essence, they were plagued by a deadly disease that went from their roots all the way to their fruit. It was all-pervasive and rendered everything about them unacceptable and unprofitable.

The lesson is a simple one: Good fruit cannot come from a bad tree. But the implications of this simple illustration are profound. Jesus is telling His disciples that it is the inner character that determines the quality or acceptability of one’s outer conduct. A diseased tree may produce fruit that looks good and appears edible, but that fruit will be contaminated and rendered useless. That’s why Jesus said it is impossible for a bad tree to produce good fruit.

And just to make sure that His disciples understood the analogy, Jesus explained the connection between fruit and followers.

“A good person produces good things from the treasury of a good heart, and an evil person produces evil things from the treasury of an evil heart.” – Luke 6:45 NLT

It all starts on the inside. Or, as Jesus put it, “What you say flows from what is in your heart” (Luke 6:45 NLT). Speech is a byproduct of the heart. So is behavior. Our words and works are the fruit that our lives produce, and if our heart is diseased, we will produce unacceptable fruit. It may look good, but it will be contaminated by the evil intent of a wicked heart. As the prophet Isaiah put it, we are “all infected and impure with sin. When we display our righteous deeds, they are nothing but filthy rags” (Isaiah 64:6 NLT).

Jesus makes it perfectly clear that the condition of a tree can be judged by the quality of its fruit. So, in other words, the true state of a man’s heart can be measured by his conduct. Just as one would never expect a thornbush to produce figs, so we should not expect righteous behavior from a person with an evil heart. And Jesus would later expand on this idea, providing His disciples with a list of the contaminated “fruit” that flows from a diseased heart.

“…the words you speak come from the heart—that’s what defiles you. For from the heart come evil thoughts, murder, adultery, all sexual immorality, theft, lying, and slander. These are what defile you.” – Matthew 15:18-20 NLT

At this point in their relationship with Jesus, the 12 disciples were all “bad” trees. Yes, they had chosen to follow Jesus, but they were not yet filled with the Holy Spirit. It would be three years before Jesus paid the price for their sins by dying in their place on the cross. His death, burial, and resurrection were future events that would provide the means for their inner heart change. But for now, they remained just as they were when Jesus called them: Dead in their trespasses and sins, condemned, unclean, and in need of the life-transforming, heart-restoring, and soul-sanctifying gift of God’s grace made possible through the sacrificial death of His Son.

Jesus knows these men desperately want to believe that He is their Messiah and Lord. But He also knows that they are going to have a difficult time accepting and going what He has said because they lack the necessary power to pull it off. He even seems to challenge their willingness to obey His teaching when He says, “why do you keep calling me ‘Lord, Lord!’ when you don’t do what I say?” (Luke 6:46 NLT). They haven’t even had time to put any of Jesus’ words into action, and yet He knows they are already questioning the validity and feasibility of His words. It all sounds impossible to them. But Jesus wants them to know how just vital it will be that they obey His commands.

“I will show you what it’s like when someone comes to me, listens to my teaching, and then follows it.” – Luke 6:47 NLT

And He provides them with yet another illustration designed to explain the importance of trusting His words even when they can’t fully understand them. They are just beginning their relationship with Jesus and the days ahead are going to be a roller-coaster ride that will test their faith, challenge their loyalty, and disrupt all their preconceived notions regarding the Messiah and His Kingdom. But Jesus wants them to know that if they listen and obey what He has to say, they will one day discover the life-saving nature of His words. Jesus describes it as a man who builds the foundation of his house on solid rock. He takes the time and effort to dig deep and secure the future state of his home, not knowing what the days ahead have in store. But Jesus assures them that their efforts to trust Him will prove profitable.

“When the floodwaters rise and break against that house, it stands firm because it is well built.” – Luke 6:48 NLT

These men have no idea what storms lie in their path, either literally or figuratively. But if they will simply trust what Jesus is telling them and place their hope in the rock-solid nature of His word, they will not be disappointed when the weather of life takes a turn for the worse. And that day is coming.

Founded on the Rock

“Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock. And everyone who hears these words of mine and does not do them will be like a foolish man who built his house on the sand. And the rain fell, and the floods came, and the winds blew and beat against that house, and it fell, and great was the fall of it.”

And when Jesus finished these sayings, the crowds were astonished at his teaching, for he was teaching them as one who had authority, and not as their scribes. – Matthew 7:24-29 ESV

For most of us, when we read these verses, we automatically assume that Jesus’ mention of “the rock” was a veiled reference to Himself. After all, He is the rock. And we get that idea from the Scriptures. Paul would later refer to Jesus as being the foundation he laid and upon which all others were to build.

According to the grace of God given to me, like a skilled master builder I laid a foundation, and someone else is building upon it. Let each one take care how he builds upon it. For no one can lay a foundation other than that which is laid, which is Jesus Christ. – 1 Corinthians 3:10-11 ESV

Peter would quote from the Book of Isaiah and the Psalms, describing Jesus as the stone:

For it stands in Scripture: “Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.”

So the honor is for you who believe, but for those who do not believe,

“The stone that the builders rejected has become the cornerstone,” and “A stone of stumbling, and a rock of offense.” – 1 Peter 2:6-8 ESV

So, it would only be natural to assume that Jesus is referring to Himself as the rock. But it is important to look closely at what He says. He prefaces these closing lines of His sermon with the statement: “Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock.”

His emphasis is on His words or the content of His message. Throughout His sermon, Jesus has been giving commands regarding the lifestyle or behavior of those who are blessed or approved by God. They are to be salt and light. They are to pursue reconciliation with all men, rather than display anger and hatred. They are to love and not lust. They are to remain faithful in their earthly commitments, most especially in the context of marriage. They are to be a people of their word. They are to live lives of willing sacrifice, rather than seeking revenge and retaliation. They are to love and pray for their enemies. Their acts of righteousness are to flow from the heart and are not to be done for recognition and the praise of men. They are to see their eternal reward as their greatest treasure, instead of finding meaning and fulfillment in the temporal things of this earth. Their lives are to be marked by a calm and unwavering trust in God, knowing that He will provide all their needs. They are to regularly examine their own lives, recognizing and repenting of their sinfulness before God. 

Over and over again, Jesus has given them clear indications of how an individual approved by God should live their life. And now, He is telling them that those who hear these words and do them will be seen as wise. They will be the ones whose lives are built upon a solid foundation.

Obedience to the teachings of Jesus has always been a necessary part of the life of the believer. Obedience does not save us, but it marks the life of those who are truly saved. Not long before Jesus was to be betrayed and crucified, He told His disciples, “If you love me, you will keep my commandments” (John 14:15 ESV). And then He told them how they were going to pull that off. “And I will ask the Father, and he will give you another Helper, to be with you forever, even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you” (John 14:16-17 ESV).

The Holy Spirit was going to be the key to them obeying the words and teachings of Jesus. But they were still expected to obey. And just to make sure that they didn’t forget anything He had taught them, Jesus let them know that the Holy Spirit would give them perfect memories.

“These things I have spoken to you while I am still with you. But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.” – John 14:25-26 ESV

One of the things we so easily lose sight of is Jesus’ statement to His disciples, found in the Great Commission.

“Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.” – Matthew 28:19-20 ESV

The disciples were to teach all that Jesus had commanded. His words were to be obeyed. And He was not just speaking of His claim to be the Messiah and His offer of salvation through faith in Him alone. Again, obedience to the words of Jesus does not save us, but it is to be the visible proof of one who is saved. Repeatedly in Scripture, we are given the admonition to obey the commands of Jesus.

“When you obey my commandments, you remain in my love, just as I obey my Father's commandments and remain in his love.” – John 15:10 NLT

The apostle John puts the non-optional nature of obedience to Jesus’ commands in very stark terms.

He himself is the sacrifice that atones for our sins—and not only our sins but the sins of all the world.

And we can be sure that we know him if we obey his commandments. If someone claims, “I know God,” but doesn’t obey God’s commandments, that person is a liar and is not living in the truth. But those who obey God’s word truly show how completely they love him. That is how we know we are living in him. Those who say they live in God should live their lives as Jesus did. – 1 John 2:2-6 NLT

So, Jesus says that whoever hears the words He has been teaching and does them, will find their life to be built on a solid, reliable foundation. Of course, the very first teaching of Jesus we must believe and obey is His claim to be the Son of God and the sacrifice for the sins of mankind. John makes this point quite clear.

…we can come to God with bold confidence. And we will receive from him whatever we ask because we obey him and do the things that please him.

And this is his commandment: We must believe in the name of his Son, Jesus Christ, and love one another, just as he commanded us. Those who obey God’s commandments remain in fellowship with him, and he with them. And we know he lives in us because the Spirit he gave us lives in us. – 1 John 3:21-24 NLT

Our ability to obey the commands of Jesus begins with our obedience to the command of God to trust in His Son as our Savior. When we place our faith in Him, we receive the Spirit of God and the capacity to love God and to love others, which are the foundational truths behind all that Jesus taught in His sermon. Our faith in Christ is to be transformative. It is to change the way we think and behave. It is to have a revolutionary effect on the way we live our lives in this world. But for far too many today, obedience seems to be optional. They place their faith in Christ and then continue to live as if nothing has happened. They give little or no evidence of the new nature they are supposed to have received. Their lives show no signs of the Spirit’s presence within them. But that is not what Jesus expected. And that is not the outcome His sacrificial death on the cross was meant to provide.

If we truly love Him, we will keep His commandments. We will conduct our lives in a radically different manner. We will be salt and light. We will be agents of reconciliation, calling a lost and dying world back to God. We will love and not lust. We will selflessly give, rather than always trying to selfishly focus our lives on getting. We will forgive, show mercy, turn the other cheek, worry less, rejoice more, pray intensely, trust God completely, and share the good news of the gospel regularly.

Jesus tells us that those who build their lives on His words will find their lives to be stable and resilient. They will have a firm foundation that can withstand the storms of life and will survive the future judgment to come. There were those in the crowd that day who would hear Jesus’ words and ignore them. Many of them would later hear of His death and resurrection and refuse to believe it. After His crucifixion, the word of His miraculous resurrection and ascension would spread, and the offer of salvation would be heard throughout all Judea, but most would not accept it. And their lives would be like a house built on sand, unstable and insecure, completely susceptible to the storms of life and unavoidably destined for a great fall.

When Jesus finished His sermon, the crowds were amazed. They were astonished at His teachings. They had never heard anything like this before. He taught with authority. Over and over again in His message, Jesus had said, “But I say….” He referred to the Old Testament Scriptures, but then added His own words. He did not refer to the teachings of the patriarchs or refer to other rabbinic scholars. He spoke as if His words were on a par with the Word of God itself, because they were. He was the Son of God, speaking on behalf of God the Father. He was the Word incarnate. John describes Him as such.

In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it. – John 1:1-5 ESV

He is the Word, and we are to obey Him, not just believe in Him.
