Beware Bitter Roots and Birthrights

Hebrews 12:12–17 “Therefore lift your drooping hands and strengthen your weak knees, and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed. Strive for peace with everyone, and for the holiness without which no one will see the Lord. See to it that no one fails to obtain the grace of God; that no “root of bitterness” springs up and causes trouble, and by it many become defiled; that no one is sexually immoral or unholy like Esau, who sold his birthright for a single meal. For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears.”

Words to listen for: Stabilizing, Pursuing, Destroying

Introduction

In 2011, a 22-year-old Derrick Rose exploded onto the NBA scene as the youngest MVP in league history. He was electric—fearless drives to the basket, impossible finishes, lightning-quick cuts that left defenders grasping at air. The Chicago Bulls rode his athleticism to the top of the standings, and the future seemed limitless.

But beneath the highlights, warning signs were flashing. Throughout that MVP season and the next, Rose battled a string of nagging injuries: sprained toes, twisted ankles, pulled groins, back tightness. His hyper-explosive style placed enormous stress on his joints and stability, yet he kept pushing, playing through pain on a relentless schedule.

Then came Game 1 of the 2012 playoffs. With the Bulls comfortably ahead late in the game and victory already secured, Rose drove to the hoop one more time. His left knee buckled on a routine jump stop—no contact, no foul. The ACL tore completely. What looked like a sudden tragedy was actually the inevitable result of ignored fatigue and overload. Those “minor” issues had quietly eroded his foundation until the big collapse came.

Rose missed an entire season recovering, returned briefly, then tore the meniscus in his other knee. Chronic setbacks followed. The explosive MVP never fully returned. He played respectably in later years, but as a shadow of his former self, retiring far earlier than anyone expected. A trajectory toward all-time greatness was forever altered because small warnings went unheeded in the heat of the race.

Friends, Derrick Rose’s story is a vivid picture of the urgent warning the author of Hebrews gives us tonight in chapter 12, verses 12 through 17.

Don’t ignore the spiritual drooping hands, the weakening knees, the root of bitterness, or the unaddressed sin. Strengthen them now—through prayer, repentance, fellowship, and God’s grace—before a minor limp becomes a disqualifying collapse.

Tonight, we’ll walk through this passage under three headings:

Stabilizing Joints, Straightening Paths (vv. 12–13)

Pursuing Peace and Holiness (v. 14)

Destroying Bitter Roots and Treasuring Birthrights (vv. 15–17)

May the Lord open our eyes to see where we—or those around us—are growing weary, and may He grant us grace to strengthen one another so that none of us limps out of the race He has set before us.

1. Stabilizing Joints, Straightening Paths

We start out with an exhortation to take care of frail body parts that are in danger of further injury. Look at verses 12 & 13.

Hebrews 12:12-13 “Therefore lift your drooping hands and strengthen your weak knees, and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed.”

This imagery of weak knees and lame feet fits with the way the author started chapter 12 with the analogy of running a race. Last time we looked at the author’s digression in which he addressed the issue of suffering and the Lord’s loving discipline. In addressing the Lord’s discipline the author focused his exhortation on his audience individually, but our passage this evening shifts the focus to his audience as a group.

As we consider verses 12 and 13 it doesn’t take too long to realize he speaking metaphorically. While it would be beneficial to watch over and care for our physical bodies, that is not the chief concern of our passage. It is intended as an analogy of spiritual health. He’s not a calling you to go see a physical therapist or a chiropractor. The language actually comes from a passage in Isaiah.

Isaiah 35:3–4 “Strengthen the weak hands, and make firm the feeble knees. [4] Say to those who have an anxious heart, “Be strong; fear not! Behold, your God will come with vengeance, with the recompense of God. He will come and save you.””

In the prophet Isaiah the poetic parallel to strengthening hands and knees is speaking words of comfort to anxious people, so we can safely assume that the author of Hebrews has a similar proposal in view.

This makes even more sense when we remember that the Scriptures often call the people of God, the body of Christ. If you are around Christians for even a short length of time you will often find them speaking of “the body.” Most often they are referring to group of believers gathered together and united to Christ by faith since that is the way the Bible talks in many places.

In 1 Corinthians 12 we find an extended discussion of this imagery which fits with what we are talking about in Hebrews 12. Let’s look at 1 Corinthians 12:14–26. This is a little bit of a longer passage which is an important foundation for understanding our passage in Hebrews. For the sake of time I’m only going read selections:

“[14]For the body does not consist of one member but of many. [15] If the foot should say, “Because I am not a hand, I do not belong to the body,” that would not make it any less a part of the body. … [17] If the whole body were an eye, where would be the sense of hearing? … [19] If all were a single member, where would the body be? …[24b]But God has so composed the body, giving greater honor to the part that lacked it, [25] that there may be no division in the body, but that the members may have the same care for one another. [26] If one member suffers, all suffer together; if one member is honored, all rejoice together.”

The Bible doesn’t portray Christians as mere individuals who show up once or twice a week to sing, pray, give, and listen to a message. When someone puts their faith in Jesus they don’t just become part of him, but they become part of the body of believers. You get a whole new identity which is rooted in a new community.

The church is called “Christ’s body” with Christ as the head. No other religious community posits such an intimate relationship with their god, because all of them are counterfeits, distortions of the God who created all things and called a people into fellowship with him through repentance and faith.

Christians have a unique bond with each other that transcends this life and lasts forever because it is rooted in their connection to Jesus Christ. So the exhortation in Hebrews 12:12–13 is to care not only for ourselves, but to be mindful of the others in the body. “Therefore lift your drooping hands and strengthen your weak knees, and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed.”

This exhortation is not so much focused on figuring out what your personal bad knee or weak ankle is spiritually. This is less about introspection and more about outro-spection. Looking around and looking out for the people around you who may be struggling. Last time was about each person considering their own personal discipline from the Lord, but now the author is telling us to look around, pay attention to the others who might be struggling in the body.

Don’t let the body get taken out by a weak ankle, a bad knee, a fragile wrist. Running the race is not an individual activity, but something we’ve got to do together. Just as our physical bodies could never run races or even walk without multiple parts all working together, the church won’t work if we ignore or leave behind believers who are struggling.

We need to understand this because sooner or later all of us will be an injured knee, a throbbing elbow, a wobbly ankle and we will need the care of others.

From the context the weak and wobbly body parts are struggling with faith. They are reconsidering whether their faith in Christ is worth the hardship and pain that come with it. In chapter 3:10 we saw that unbelieving Israel is said to “always go astray in their hearts…”, thus the exhortation in our passage to “make straight paths for your feet.” Going astray meant failing to continue in the faith and so making a straight path means persevering and continuing in faith.

Imagine helping someone with crutches to walk. Are you going to leave all kinds of junk in front of them to navigate around and hop over? Of course not. You’re going to get everything cleared out of the way to help them get through so they don’t injure themselves worse.

The danger of weak joints in the body is not only the danger they pose to themselves, but to the entire community.

My father-in-law got knee replacement surgery a few years back and he stayed at our house while he was recovering. I was so surprised that the day after got the surgery the physical therapist had him trying to walk and bend his knee right away. He said that it was to promote the proper healing. If they knee stayed in one position it would heal wrong.

Sometimes we need a little gentle prodding and encouragement spiritually so that we continue in the faith. We need people asking us how we’re doing, whether we’re reading our Bibles, whether we’re spending time in prayer, why we’re not in worship. And we need to be those that ask others about their spiritual life, in a spirit of encouragement and not judgment, since there is just as much grace for the sins of others as for our own. There are serious eternal consequences at stake.

This leads into the next thing that the author addresses:

2. Pursuing Peace and Holiness

Look at Hebrews 12:14 “Strive for peace with everyone, and for the holiness without which no one will see the Lord.”

We start off with a word that resonates with the prevalent running imagery. The word translated “strive” is διώκω in Greek which means “to set in quick motion” or “pursue.” In other passages it is used to describe persecution. The idea is that peace and holiness must be urgently pursued within the church.

As with verses 12-13 this is not merely an individual endeavor. This exhortation flows directly out of what we saw in verses 12-13. One commentator says, “The previous verse concluded with an exhortation to “make straight paths for your feet” (12:13), and the author will now explain how that is done. In a word, the straight paths are the paths of Christian fellowship.”

The peace and holiness which are to be pursued must be done in community, and they don’t happen automatically.

Peace is something that lots of people are thinking about this time of year because it is famously what the angelic messengers told the shepherds was coming with the birth of Jesus. Jesus’ work, what he was going to do by dying and rising, brings us peace with God. But even more than that his person, who he is as fully God and fully human, also brings us peace with God.

Romans 5:1–5 connects some of the dots of peace and holiness in the Christian experience: “Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. Through him we have also obtained access by faith into this grace in which we stand, and we rejoice in hope of the glory of God. Not only that, but we rejoice in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope, and hope does not put us to shame, because God’s love has been poured into our hearts through the Holy Spirit who has been given to us.”

Peace with God leads to sanctification in our lives according to God’s fatherly discipline as we saw in Hebrews 12:4-11. Even though Paul doesn’t use the word “sanctification” the concept is present here as he moves from the peace we have with God to the formative power of suffering which is what sanctification is. From Hebrews we’ve seen that holiness is the outcome of Jesus’ high priestly ministry (Heb 9:14; 10:10, 10:14; 13:12) and the heavenly Father’s molding of his children (Heb 12:10).

Peace and Holiness are something that God gives therefore we should make every effort to see it manifested in our community. Peace has many aspects to it, but what seems most in view in verse 14 of Hebrews 12 is peace between members. Injured joints are more likely to pull away, try to isolate and have their wounds fester.

One commentator says: “The author’s description reflects the organic connection between one’s relationship with God and one’s relationship with his people. Apostasy from God manifests itself as alienation from and conflict with God’s people.”

Pursuing peace means it won’t come without uncomfortability, at least awkwardness. Peace doesn’t just happen, it has to be chased down. It requires an active approaching those we have problems with, intentionally talking to those we don’t like, with the intention of reaching understanding or at least greater unity. Loving confrontation of problems head on is the only way to find true resolution to strong disagreements.

It’s always easier to see people as completely defined by their one or ten worst traits when we don’t interact with them. That’s why the author says we’ve got to pursue peace. We can’t just sit around hoping it will happen. That’s what I’d prefer to do. Just ignore it and hope somehow peace happens. But that’s not how peace happens in the body of Christ and it’s not how holiness happens.

Holiness is also a community project. That doesn’t mean you make it your business to highlight everyone’s sin whenever you see it. I’m thinking more about how you by yourself can’t see all the ways you aren’t living like a Christian. Just like how you can’t see yourself all at once in the mirror you can’t see yourself spiritually. Sin is inherently blinding and even as believers we still are not completely free from its presence.

There’s a corporate aspect to this like with Hebrews 10:24–25 “And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near.” We’re called to pursue holiness by encouraging one another to stay involved and keep using the means of grace to grow individually and as a body.

In our passage the importance of pursuing peace and holiness is emphasized by a warning against the alternative but this is underscored by the final warning.

3. Destroying Bitter Roots, Treasuring Birthrights

Look at Hebrews 12:15 as we come the climax of this passage: “See to it that no one fails to obtain the grace of God; that no “root of bitterness” springs up and causes trouble, and by it many become defiled;”

The exhortations we’ve seen—strengthening weak knees, making straight paths, pursuing peace and holiness—all build to this urgent warning. Having just said that without holiness no one will see the Lord, the author now paints the dark alternative: a community where grace is missed, bitterness takes root, and many are defiled.

First, let’s consider what this “root of bitterness” is referring to. It’s easy to hear “bitterness” and think of personal grudges or unforgiveness—and pursuing peace certainly guards against that. But it’s actually a reference to Deuteronomy 29:18-19.

Let’s go back and take a look at this phrase in its context: Deuteronomy 29:18–19 “Beware lest there be among you a man or woman or clan or tribe whose heart is turning away today from the Lord our God to go and serve the gods of those nations. Beware lest there be among you a root bearing poisonous and bitter fruit, one who, when he hears the words of this sworn covenant, blesses himself in his heart, saying, ‘I shall be safe, though I walk in the stubbornness of my heart.’ This will lead to the sweeping away of moist and dry alike.”

This is near the end of Deuteronomy and Moses is warning the Israelites here about the possibility of secret but contagious apostasy. The bitter root is not about unforgiveness towards others, but about turning away from God. So it makes perfect sense why the author of Hebrews would be referencing it. This is another way of him saying what he’s been saying already, that you have to nip apostasy in the bud both privately and as a body. Don’t let apostasy grow as though it were harmless.

When we look closely at Deuteronomy 29 we see that apostasy grows in the soil of presumption. Verse 19 describes someone who tells himself that he doesn’t need to worry about judgment even though he’s unrepentant. There have always been individuals who were part the community of God and thought that their public corporate identity would keep them safe even though their hearts weren’t changed.

The author of Hebrews is concerned that the same kind of dangerous presumption could be present in the community he is writing to. Presumption spreads dangerously in our own lives and in the lives of the community of God and in the end it leads people to think that they don’t even need the larger community either. If you don’t need personal heart change to be saved from hell, why do you actually need to identify as a Christian, especially when it might be uncomfortable or cost something?

The author of Hebrews moves on with an illustration to drive home his point, the tragic story of Esau.

Look at Hebrews 12:16–17 “that no one is sexually immoral or unholy like Esau, who sold his birthright for a single meal. For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears.”

Now, at first we might be puzzled by the introduction of sexual immorality. But when we realize that in the Old Testament God constantly compares idolatry to sexual unfaithfulness it makes a lot more sense. We don’t have a record of Esau being especially flagrant in sexual immorality. He did marry Hittite women who were unbelievers which was wrong, but he was not known for sexual immorality. Most likely Hebrews 12 is speaking figuratively about Esau’s abandonment of faith.

The word “unholy” is translated by some other Bible translations as “worldly.” This worldliness of Esau led him down a dangerous path so that he no longer valued things that are valuable. He saw a bowl of stew as more valuable than his birthright.

Very likely you remember the story, Esau came in hungry from hunting and asked his brother for the stew he made. Jacob, not very upstanding himself, drove a hard bargain demanding the birthright of firstborn he had missed by few minutes. Instead of haggling, Esau handed it over with hardly a moment’s thought. Jacob took advantage of the situation, but Esau revealed his own disregard of his birthright.

Not only was Esau foolish in terms of physical inheritance, but even more so because of what it represented spiritually. Spiritually the birthright represented the inheritance of faith that God had promised Abraham. Esau treated God’s covenant blessing as worth nothing more than a bowl of stew.

This is where presumption will take us all if we’re not careful. Presumption upon God’s grace means taking it for granted. Those who are trusting on Christ for salvation should be able to rest on God’s grace for them, rather than constantly questioning it. But those who are truly resting on God’s mercy in salvation are equally aware that they do not deserve it and this drives them to repeated repentance when they act according to the sin nature which remains in them.

Presumption, on the other hand, is counterfeit assurance. It begins to wonder if grace really was so underserved after all and it feels less and less of a need for repentance. Presumption is more likely to find loopholes and excuses for why we can’t be expected to live perfectly after all, instead of repenting and turning to God for mercy.

The people of Israel, generally, had major problems with presumption throughout their history and when John the Baptist showed up it was still strong. In order to shock them out of their presumption that as native Israelites they had an inherent right to God’s favor John said this in Matthew 3:9–10 “And do not presume to say to yourselves, ‘We have Abraham as our father,’ for I tell you, God is able from these stones to raise up children for Abraham. Even now the axe is laid to the root of the trees. Every tree therefore that does not bear good fruit is cut down and thrown into the fire.” Their presumption had led them to completely disregard God’s law and assume they were fine.

But the Pharisees, on the other hand, had started out dead set on obeying God’s law completely and setting Israel on a path of reform. Yet, somewhere along the line, instead of regularly repenting for their sin, they began to make excuses for their failures and exceptions for themselves. They started presuming upon God’s favor on the basis their own superficial self-righteousness.

Whether dismissing God’s law outright or studiously exempting oneself from the difficult parts of God’s law, presumption at it’s heart leads to a lack of repentance. This is precisely what we see in Esau. Look again at Hebrews 12:17 “For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears.”

Esau’s bitter root of presumption had grown into full flower as he pursued temporary fleeting pleasures of sin until it was too late. There does come a time when it is impossible to repent. That certainly comes at death for all of us. “…it is appointed for man to die once and then comes judgment…”

In terms of before death I don’t think we can easily say when that might be for either ourselves or others. The Bible does not call us to make that judgment call, it simply calls us to repent. Esau serves as a warning to us all not to test that limit. Don’t presume you’re in control of tomorrow’s grace. He lived his life thinking that he could simply repent whenever he wanted. He was presuming he was in control. But when he saw the consequences, when he had eaten his fill of sin he thought he could just flip the switch for himself—he was wrong.

Repentance always has been and always is a gift of God. It is part of his grace, because it requires not merely seeing the consequences of sin as fearful, but to see sin as repulsive in itself. It doesn’t take special grace to find everlasting torment terrifying. It does take supernatural grace for a sinner who loves sin and hates holiness to turn completely into a person who finds sin repulsive and God delightful.

That’s the kind of miracle that God does every day. That’s why this warning was written down, preserved, translated, read, and preached to you this evening. So that by hearing this warning about Esau you wouldn’t waste another moment thinking you can repent later whenever you want, you would ask God for that grace right now.

God’s not looking for perfection asking you to turn your life around before coming to him to ask for help. In fact, the less you try without him the better. Anything you try to do in your own strength, any righteousness you try to accomplish in your own strength is worthless and even insulting to God.

Esau’s solution to Isaac’s displeasure was to double down on his sin. Genesis 28:8–9 “So when Esau saw that the Canaanite women did not please Isaac his father, Esau went to Ishmael and took as his wife, besides the wives he had, Mahalath the daughter of Ishmael, Abraham’s son, the sister of Nebaioth.” Don’t double down, repent, even better ask God to help you repent and then believe in the free grace of God that covers you in love. Don’t presume upon it, but do rest in it, trust it to hold you, and trust God to never let you go.

Brothers and sisters, Hebrews 12 has hit us hard tonight. Let’s review:

Stabilize the weak—lift drooping hands, strengthen feeble knees, clear straight paths. We run together; one limping member slows the whole body.

Pursue peace with everyone and the holiness without which no one will see the Lord. Chase them hard—they won’t come easy.

Destroy bitter roots before they destroy us. That hidden presumption—“I’m safe while I live in rebellion”—poisoned Esau. He traded his priceless birthright for stew, then wept when repentance was gone forever.

We can ignore the warning signs until the collapse. Or we can act now.

Lift the weak. Pursue peace and holiness. Uproot presumption. Treasure your birthright in Christ—the inheritance that never fades.

God isn’t waiting for you to get it together. Come weary, limping, empty. Ask Him tonight to grant repentance—to hate sin and love Him more. Ask Him to knit us together so no one misses His grace.

Then rest—boldly rest—in the Savior who holds you fast and gives his Spirit to carry us all home to see Him face to face. Amen
