Hebrews: The Word of God is Living and Active
Hebrews 4:12-13; Revelation 19:11-16 - There are many aspects of the vitality and sharpness of the Word of God!
“For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart. And there is no creature hidden from His sight, but all things are open and laid bare to the eyes of Him with whom we have to do.”
Hebrews 4:12-13 NASB1995
It would be interesting to have a vote from believers on verse 12 on how many have either memorized this verse or have it highlighted in their Bibles (I have it highlighted). But the big question (and one of the problems with highlighting verses) is that the context is often ignored the next time you read through that passage of scripture if you are not paying attention. Your brain tends to focus on what has been highlighted, rather than realizing that this verse is a pivot point around the repetitive concerns of diligently finding rest and being obedient TODAY through the salvation of Jesus. The writer of Hebrews is targeting those new believers in Christ (most likely Jewish converts) who are wobbly in their belief.
My resources have so much good stuff about verse 12 that it’s a dilemma picking the best commentary. Perhaps it would be good to parse out this verse piece-by-piece and dive into various aspects.
First, the word of God is living and active and sharper than any two-edged sword..
Precept Austin conveniently supplied this nice list of quotes about the word of God from various Bible scholars:
Vance Havner “The storehouse of God’s Word was never meant for mere scrutiny, even primarily for study but for sustenance.
Scottish pastor Thomas Cuthrie - “The Bible is an armory of heavenly weapons, a laboratory of infallible medicines, a mine of exhaustless wealth. It is a guidebook for every road, a chart for every sea, a medicine for every malady, and a balm for every wound. Rob us of our Bible and our sky has lost its sun.”
Will H. Houghton “The Bible calls itself food. The value of food is not in the discussion it arouses but in the nourishment it imparts.
A W Pink “God’s design in all that He has revealed to us is to the purifying of our affections and the transforming of our characters....Everything in Scripture has in view the promotion of holiness.
Leon Morris - The Word of God is unique. No sword can penetrate as it can.
D L Moody - The Scriptures were not given to increase our knowledge but to change our lives.
Thomas Brooks - “The Word of the Lord is a light to guide you, a counselor to counsel you, a comforter to comfort you, a staff to support you, a sword to defend you, and a physician to cure you. The Word is a mine to enrich you, a robe to clothe you, and a crown to crown you.
John Flavel “The Scriptures teach us the best way of living, the noblest way of suffering and the most comfortable way of dying.
Martin Luther - “The Bible is alive, it speaks to me; it has feet, it runs after me; it has hands, it lays hold on me.”
Frank Cooke “The foundation of every reformation of the Holy Spirit is the Word of God made plain to the people.
Brian Edwards - Philosophy and religion may reform, but only the Bible can transform.
Vance Havner - “There is no devil in the first two chapters of the Bible and no devil in the last two chapters. Thank God for a book that disposes of the devil!”
A few key takeaways:
The Word of God is nourishment and sustenance.
The Word of God is unique among written works.
The Word of God transforms us.
The Word of God is alive and running after us.
The Word of God teaches us how to live and die.
The Word of God is light.
The Word of God is an armory of weapons.
The Word of God is a guidebook and map.
The Word of God is a mine to enrich us.
The Word of God promotes holiness.
This commentary from Precept Austin and from Charles Spurgeon, quoted in the same part of the commentary tells us what the sharpness of this sword, representing the Word of God, means:
The Word of God is the sharpest weapon in any arsenal—sharper than the finest surgeon’s scalpel. It is two-edged, with no blunt side. Every book, chapter, verse, and word is razor-sharp, able to cut deeply; there is not a dull line in the entire Bible. Because it is two-edged, it cuts both ways—it comforts the afflicted and afflicts the comfortable; it tears down and builds up; it convicts and converts. It brings both bad news and good news; it saves and condemns; it heals and hardens; it gives life and puts to death.
It is alive in every part, and in every part keen to cut
the conscience, and wound the heart.Spurgeon on sharper that any two-edged sword - The revelation of God given us in Holy Scripture is edge all over. It is alive in every part, and in every part keen to cut the conscience, and wound the heart. Depend upon it, there is not a superfluous verse in the Bible, nor a chapter that is useless. The Word of God is so sharp a thing, so full of cutting power, that you may be bleeding under its wounds before you have seriously suspected the possibility of such a thing. You cannot come near the gospel without its having a measure of influence over you; and, God blessing you, it may cut down and kill your sins when you have no idea that such a work is being done. Yes, when Christ comes, He comes not to send peace on the earth, but a sword; and that sword begins at home, in our own souls, killing, cutting, hacking, breaking in pieces. Blessed is that man who knows the Word of the Lord by its exceeding sharpness, for it kills nothing but that which ought to be killed. It quickens and gives new life to all that is of God; but the old depraved life, which ought to die, it hews in pieces, as Samuel destroyed Agag before the Lord (1Sa 15:33).
Have you ever been at church and marveled at the fact that the sermon being preached seems to be targeted directly at you? Sometimes it is comforting, sometimes it is convicting, but it is completely on target and “just in time”. Charles Spurgeon talks about this supernatural quality of the sharp word of God (in Precept Austin):
Many and many a time have persons written to me or spoken with me and said, “Did you intend in the sermon to make a personal allusion to me?” I have said, “Yes, I most certainly did. But I never saw you in my life and never knew anything about your case; only he that sent me commanded me to say this and that, and he knew who would be there to hear it, and he took care to guide my thoughts and words, so as to suit your case exactly, so that there could be no mistake about it.”
Speaking of the effectiveness of Charles Spurgeon in the pulpit, if you have time read this piece from Desiring God on how Spurgeon’s ability to convict parishioners of the hopelessness of sin and death without Christ led to thousands of conversions.
Enduring Word also has marvelous commentary about the Word of God; David Guzik uses the NKJV translation, so the phrasing in the first part of verse 12 is “living and powerful”. Links are provided to various verses:
b. Living and powerful: When the word of God exposes our weakness and unbelief like this, it demonstrates its inherent power, sharpness, and accuracy. It bears constant reminding that as we submit ourselves to the word of God, we do it for far, far more than intellectual knowledge or to learn Bible facts. We do it for the ministry of the Word, because God meets us in His Word and the Holy Spirit works powerfully through the word of God. This spiritual work of God’s Word goes far beyond the basic educational value of learning the Bible.

Pretty good stuff!!!
In Revelation, John sees a sword in the mouth of Jesus five times, emphasizing the power of the Word. Here is the vision as described in Revelation 19:
“And I saw heaven opened, and behold, a white horse, and He who sat on it is called Faithful and True, and in righteousness He judges and wages war. His eyes are a flame of fire, and on His head are many diadems; and He has a name written on Him which no one knows except Himself. He is clothed with a robe dipped in blood, and His name is called The Word of God. And the armies which are in heaven, clothed in fine linen, white and clean, were following Him on white horses. From His mouth comes a sharp sword, so that with it He may strike down the nations, and He will rule them with a rod of iron; and He treads the wine press of the fierce wrath of God, the Almighty. And on His robe and on His thigh He has a name written, “KING OF KINGS, AND Lord OF LORDS.””
Revelation 19:11-16 NASB1995
Second, …and piercing as far as the division of soul and spirit, of both joints and marrow and able to judge the thoughts and intentions of the heart.
A decent battlefield sword would not only have sharp edges, it would have a tip that is sharpened to a very fine point to allow for rapid piercing of an enemy, like the example of a sword tip in the photo above. A blunt-ended sword is not very useful at close range (not to be too graphic).
The Word is piercing, dividing soul and spirit, marrow and joint. So how can the Word of God divide soul and spirit? What does this mean? Gotquestions.org has a good answer to this question:
So, if the Word of God can divide soul and spirit, what is the difference between the soul and the spirit? One way to look at it is that the soul is the “life force” of a person; it is the essence of humanity’s being. The spirit is related to the soul but is more specifically the immaterial part of humanity that connects with God. As commentary puts it, the Word of God reaches “even to the separation of the animal soul, the lower part of man’s incorporeal nature, the seat of animal desires, which he has in common with the brutes; compare the same Greek, 1Co 2:14, ‘the natural [animal-souled] man’ (Jude 19), from the spirit (the higher part of man, receptive of the Spirit of God, and allying him to heavenly beings)” (Jamieson, R.; Fausset, A.; and Brown, D.; A Commentary, Critical, Practical, and Explanatory on the Old and New Testaments, 1882, entry for Hebrews 4:12).
There is another way to see this passage, however. Some Bible scholars consider the soul and spirit to be one and the same thing. Instances of the phrase soul and spirit are simply a writer’s way of emphasizing the totality of the inner person. As Heinrich Meyer puts it, the reference to “soul and spirit” (and “joints and marrow”) is “a figurative expression to denote the innermost, most hidden depth of the rational life of man” (New Testament Commentary, 1880, entry for Hebrews 4:12). And John MacArthur says, “These terms [soul and spirit] do not describe two separate entities (and more than “thoughts and intentions” do) but are used as one might say “heart and soul” to express fulness. . . . Elsewhere these two terms are used interchangeably to describe man’s immaterial self, his eternal inner person” (The MacArthur Study Bible, English Standard Version, Crossway, 2010, p. 1,853).
Whether the soul and spirit actually have a dividing line, the written Word of God is living, sharp, and powerful and has the ability to judge our thoughts. Scripture has a way of laying open our innermost feelings and desires, exposing our secrets, and forcing honesty before the God who created us.
This is quite illuminating. Whether you consider the soul to be the “anima” of our living being and the spirit to be of God or you consider them to be joined together, they are made by Him.
Marrow and joint are tough layers to pierce physically, just like piercing soul and spirit. I warned you, dear readers, that there would be lots of good commentary for this passage. Here is what John Piper says about this passage in one of his amazing sermons:
So let’s read again what it says about this Word. Verse 12:
For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart.
Now I am tempted to take every word here and probe into why it is used. Like, why mention joints and bone marrow? And what’s the difference between spirit and soul? And what precisely is the difference between thoughts and intentions? And do the words “living and active” perhaps correspond to any of these other pairs: spirit-soul, joints-marrow, thoughts-intentions? Is the “heart” (mentioned at the end of the verse) different from the soul and spirit? And so on. These are good questions and they are worth meditating on for hours.
But this morning I don’t want to lose the forest for the trees. I wonder if we couldn’t all agree on this much from verse 12: one of the functions of the Word of God when it comes into us is that it penetrates very deep—like a sword through tough, hard layers—and makes judgments about what’s there.
The word “judge” in verse 12 (”to judge the thoughts and intentions of the heart”) does not mean “condemn.” It means “assess.” When we show somebody a painting and say, “What’s your judgment?” we don’t mean, “What’s your condemnation?” We mean, “What’s your assessment of the quality? Is it good or bad?” So the Word of God penetrates to the deepest place in our lives and assesses what’s there. Is it good or bad?
That last paragraph of the Piper commentary is especially potent. Most humans have a conscience, regardless of their beliefs (or at least they used to have one). When I was wandering in the dark wilderness of secular humanism and finding ways to deny God, I would often hear a voice in my head (I’m not kidding - I actually heard it) telling me that I was WRONG. When we add the Word of God as the foundation of the toolkit of conscientious discernment, we can become better and better at judging something as being good or bad for ourselves (a word of caution on that judgment for others is in the commentary below).
This commentary was on Precept Austin about pretending that we know what is in someone’s heart and then judging them wrongly. I don’t know who the author was (it was not noted):
My wife and I were stopped at a railroad crossing to allow a train to pass. As we waited in the line of cars, the driver next to us suddenly darted through a nearby parking lot and headed in the direction of the next available railroad crossing.
I turned to Marlene and said, with some righteous indignation, “Look at that guy. He’s trying to get around the train instead of waiting like the rest of us.” As soon as I said those words, the man, camera in hand, hopped from his car to take pictures of the oncoming train. I had judged his motives, and I was dead wrong.
Although we can observe behavior and outward appearance, only God can see what’s in the heart. That is one reason we all need the Word of God so desperately. Hebrews 4:12 says, “The Word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.”
When we find ourselves ready to judge another person’s motives, let’s pause and remember—only God can see the heart, and only His Word can expose its motives. Our responsibility is to let the Lord and His Word convict us about our own hearts.
The Bible is a lamp from God,
A sword of truth and light;
It searches heart and soul and mind,
And helps us know what’s right.
—BoschPeople will be judged by the way God sees them not by the way we see them.
Let’s quickly look at verse 13 of this passage, repeated below so that you don’t have to go to the top:
And there is no creature hidden from His sight, but all things are open and laid bare to the eyes of Him with whom we have to do.”
The omniscience of God is what frightens people the most, especially those that have the most to hide. This ability of God to know everything in our hearts and minds is like the most powerful scanning device in the known universe. We must be eternally grateful that He is good and holy! If we give up on Jesus, that cannot be hidden from Him. Our sins and our actions are not secret and will never be secret. And that Godly scan also includes those actions we do that please Him (a comforting thought)! Growing close to Him through His Word and growing in holiness will keep us confident in His promises.
I have two more stories to share from Precept Austin for verse 13:
From Duffy Robbins:
I make it my policy to never lift up the cushions on our sofa. Before this policy was in place, I once made the mistake of looking for a pen under those cushions. What I discovered was a nightmare of leftover cookies, popcorn, used tissues, a smashed doughnut and the wise man we’d been missing from our nativity scene for three Christmases. And I was faced with the unhappy prospect of having to clean up the mess.
It has been said that the Bible will keep you from sin, or sin will keep you from the Bible. It’s true. Scripture exposes the underneath places of our lives, those places we would rather not see, and exposed sin requires that we allow Christ to clean up the mess. That’s not always easy, especially if we’ve become comfortable with our disobedience.REFLECT: Do you find yourself unwilling to expose yourself to the probing light of God’s Word? Perhaps it is for fear of what you might discover.
Don’t be afraid to turn over the cushions! I also like the two-edged sword that the Bible will keep you from sin or sin will keep you from the Bible.
From Joni Tada:
My friend Sherrill and I used to sit with each other in our wheelchairs and talk about heaven. We spoke fondly and wistfully about the day when we would take that first heavenly step on strong resurrected legs. But Sherrill had one reservation. It was that part where the Bible says of the Lord that “everything is uncovered and laid bare” before his eyes. She shuddered at the idea. “Joni, I’m so worried about all the mistakes I’ve made — the failures and the awful sins.”
I understand. The fear of the Lord is a deterrent to sin. Our Father in heaven tells us to be holy, as he is holy. Shedding sinful habits is a key and critical sign that we’re truly growing in the Lord. But that doesn’t mean Sherrill needs to be afraid. On the contrary, think of the flipside of Hebrews 4:13. God’s eyes don’t miss the good you do, either. The times you hold your tongue … the times you patiently endure suffering, leaning on Jesus … the times you hold up under pressure with a godly response … the times you give, secretly, with no thought of return … the times you offer an encouraging word when you are bone tired — all is laid bare before his searching gaze.
Maybe Sherrill’s solitary and lonely apartment seemed hidden away from the sight of others, but nothing was hidden from God’s sight. He took note of her patience, her endurance, and her faithfulness.
Fear the Lord; it’s the beginning of wisdom. But then do the wise thing: fall in love afresh with your Savior, your High Priest, who has been tested in every way like you. Live life under his gaze, knowing beyond all doubt that it’s a look of love.
Lord, the servant girl Hagar once named you “the One who sees me.” That was after you rescued her and provided for her in your kindness. Help me to remember today, that you never, never lose sight of me. [from HEBREWS 4:13 Pearls of Great Price: 366 Daily Devotional Readings - Page 23]
