“Whoever is not with me is against me, and whoever does not gather with me scatters. And so I tell you, people will be forgiven every sin and blasphemy. But blasphemy against the Spirit will not be forgiven. Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.” (Matthew 12:30-32, TNIV)

“Truly I tell you, people will be forgiven all their sins and all the blasphemies they utter. But whoever blasphemes against the Holy Spirit will never be forgiven, but is guilty of an eternal sin.” (Mark 3:28-29, TNIV)

Recently, a group of atheists actually encouraged people to “deny the Holy Spirit” online by saying the words “I deny the Holy Spirit” and uploading a video! Of course, the passages above say nothing about ‘denying’ the Holy Spirit. Clearly there is more to it than merely speaking certain words; if that were all it took, everyone who read that Bible verse aloud would have committed it!

But the fear of having committed this “unforgivable sin” can sometimes haunt Christians, usually because they are unclear about what exactly it is. What is the so-called “unforgivable sin”? And how can we know if we’ve committed it?

It is not merely an academic question; it’s something many Christians agonize over. Rev Dr Victor Shepherd, who has also been a pastor for several decades, describes some of his congregants’ fears:

I have been a pastor for 27 years. In that time I have had scores of people huddle in my study and confess what they could barely bring themselves to mention: falteringly they have croaked out what they regard as heinous, so heinous as to have been mentioned to no one else. They have poured out vile mixtures of vice, immorality, folly, even criminality. And I have told them with conviction that as wide and deep as their depravity is, God’s forgiveness is wider and deeper still. And I have assured them that however inexcusable, horrific, and even despicable the sin they have committed, they have not committed the “sin against the Holy Spirit.” And I have told them that Jesus Christ himself authorizes me to press all of this upon them.1

How is it possible that Dr Shepherd knows these people have not committed this “sin against the Holy Spirit”? In order to determine that, we first must understand exactly what Jesus was referring to.

First we should be careful to note that calling this “sin against the Holy Spirit” is misleading, as Dr Shepherd himself points out. What Jesus actually says is that “whoever blasphemes against the Holy Spirit will never be forgiven” (Mark 3:29). Clearly “sin” and “blasphemy” are different since in Matthew 12:31 Jesus refers to “sin and blasphemy” separately. So what Jesus is talking about here is not merely sin but blasphemy. The Greek blasphe?mia means “vilification (especially against God): – blasphemy, evil speaking, railing.”2 So here the properly termed blasphemy against the Holy Spirit seems to refer to speaking evilly about God; not merely as a one-time utterance but as an active and ongoing opposition. It is to witness God’s goodness and call it (and continue to call it) evil.

What specific evil was spoken about God in Matthew 12 (Mark 3)?

In context, Jesus has been performing miracles, and the Pharisees, who have witnessed these miracles, claim that Jesus did these good works “by the power of Beelzebub [Satan]” (Matthew 12:24). Thus these Pharisees denied the power and authority of the Holy Spirit and attribute it instead to Satan! These Pharisees, “who, though they knew the miracles of Christ were wrought by the Spirit of God, yet maliciously and obstinately imputed them to the devil, with a view to obscure the glory of Christ, and indulge their own wicked passions and resentments against him.”3

This reinforces what we already know: That someone who has consciously rejected God cannot be saved, because they have rejected their only path to salvation: “I am the way and the truth and the life. No one comes to the Father except through me.” (John 14:6) Since the power of God’s Holy Spirit is the means by which we are saved, a person who rejects Him cannot be saved.

Biblical scholar Ron Rhodes explains:

The Holy Spirit brings conviction upon people and leads their hearts to repentance, making people open and receptive to salvation in Jesus Christ. So the one who blasphemes the Holy Spirit effectively separates himself from the only one who can lead him on the path to salvation in Jesus Christ.4

What does this mean for the Christian who is worried that they have committed blasphemy against the Holy Spirit?

  1. Blasphemy against the Holy Spirit is not merely a certain sin or cursing God in a moment of anger or misery. Nor is it merely saying or writing the words “I blaspheme the Holy Spirit.” Any sin can be forgiven if a person honestly confesses, repents, and asks God for forgiveness, as Jesus Himself says in this passage: “people will be forgiven every sin and blasphemy” (Matthew 12:31) and as we read in 1 John 1:9: “If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.”
  2. Only someone who has totally closed themselves off from God’s love and marvelous offer of grace could be so calloused as to continually and unrepentantly call God and His glorious works “evil”.
  3. Thus, if you are worried that you have committed blasphemy against the Holy Spirit, you could not possibly have done it, for someone whose heart is so calloused would not be at all concerned about such a thing! Dr Shepherd comments that a person’s “apprehension is proof positive that the Holy Spirit hasn’t been blasphemed and the power of God maligned.”5

Doubt or weak faith are not the same as blasphemy against the Holy Spirit. Dr Shepherd concludes:

The weakest faith; the most faltering discipleship; the most hesitant, doubt-filled following; honest doubt and genuine perplexity; all of this our Lord sees and notes and helps. None of it will he scorn or dismiss. And none of it must we ever, ever suggest to be anything approaching the blasphemy against the Spirit. Weak faith he strengthens; faltering faith he makes resolute; genuine perplexity he addresses. … He has nothing but compassion and help for all who cry that their struggle for faith is just that: a struggle.6

Friend, if you have accepted God’s glorious offer of forgiveness, confessed your sin, and pledged to give your life over to Him in faith, you are reborn. “In Christ Jesus you are all children of God through faith” (Galatians 3:26, TNIV). And for those who are in Christ there is no condemnation. (Romans 8:1) Therefore, “if anyone is in Christ, the new creation has come: The old has gone, the new is here!” (2 Corinthians 5:17, TNIV)

If your soul has been tormented by fear that you have committed blasphemy against the Holy Spirit, know today that if the Spirit of God lives within you, you who are a new creation, you must not fear.

“May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit.” (Romans 15:13)

    Prasad, is there some particular event or reason for your apparent anger?

  • Prasad says:

    God can go and [expletive removed] himself.

  • Elkay Elkay says:

    I don’t recall the exact Christian theology source for this but the author observed that is was not the spoken words giving Satan for good works of Christ or the Holy Spirit that makes this particular sin unforgivable. What makes it unforgiveable is how hardened against the things of God that person’s heart has to be to think and say such thoughts aloud. Much like the “profane Esau” who “was rejected for he found no place for repentance though he sought it diligently with tears” (Heb 12:16-17).

  • concerned says:

    Aldo thank you for your reply…Joyce Meyer wrote in her book something,I could understand about my concerns, it’s in her book GOD IS NOT MAD AT YOU..and she writes that a boy is told ” do not touch that glass table ! “..and sure enough, into his mind, goes the thought about the glass table, he probably never thought about that table before that “law” was mentioned “..so sure enough, when no on was looking he touched the glass table.When I read this I could associate with this..as in ” anyone who says anything against the HOLY SPIRIT will not be forgiven “, ‘it’s like that, suddenly it becomes a law. that nothing must be said, but of course we can say words but most certainly NOT meant them…I love sharing Jesus as much as I can, in as many ways as I can too…Many thanks

  • Aldo says:

    Concerned, when someone gives credit to Satan- or anybody else for that matter- for what the Holy Spirit has brought about, that is blasphemy against God the Holy Spirit, and is the unpardonable sin. I pray that those who are God’s are never guilty of it. Amen.

  • concerned says:

    Dear Christ thank you so much.as I tried to explain it all those years ago to someone..it’s like GOD saying for example, silly as it might sound..but if GOD said ” don’t say this sentance”, or if there was a painted line at the front of the church, and God says ” do not stand on that line or else “, or don’t turn away from GOD..and it’s like the terrible temptation ” not to do “..hence ” will never be forgiven “, tempted my heart, ..etc etc..I had an amazing beginning to my Christian life, and have always wanted to follow GOD and JESUS..but then felt stuck/trapped etc..thanks

  • Chris says:

    concerned….read Matthew 12 in its entirety. that way you can get Matthew 12.32 in its context. jesus had just cast out a blind and dumb spirit from a man with those symptoms. the pharisees accussed jesus of doing it by the power of satan. that is the unpardonable sin, accusing jesus of using satans powers to cast out demon spirits. so you see you are innocent!!

  • concerned says:

    I have been so concerned about this sin..I read anyone who says anything against the HOLY SPIRIT will never be forgiven, I gave my life to JESUS years ago and love being a CHRISTIAN but this time I read this passage and thought ” well, we can say words, not mean them, just bring them forth and say things “..then I read ” will never be forgiven “, and something not good inside myself wanted to commit this sin..so in my heart I committed this sin, then ran to my minister…still wanted to be a CHRISTIAN but for years this statement has bothered me especially about 2 years ago when I suddenly felt very lost and far from GOD..thanks xxx I repent of every sin, everything and come to JESUS as in John 6/37 daily

  • Chris says:

    chiara….its true that simply accepting God intelectually isnt the same as receivng him for ones true salvation. in that sense you could be correct but whatever others do or dont do, shouldnt stop me from beleiving and receiving as christ commands. blessings!

  • chiara says:

    Have i said a blasphemy? I said that a person who accepts god and a person who rejects god are no different. Is it blasphemy?

  • Jamie Jamie says:

    Hi Tyler, what has led you to make that decision?

  • Tyler Lovell says:

    I deny the holy spirit.

  • Elkay Elkay says:

    Diane, maybe you took God’s name in vain; that’s breaking one of the 10 Commandments and is forgiven upon repentance and request. The “unforgivable sin” is an entirely different matter . . . The Pharisees saw Jesus perform miracles (the goodness of God) and gave credit to Satan for doing the miracle. They could only do that from a hardened heart that would not, could not seek forgiveness. Please read 1 John 1:9 and take it to heart. God loves you and wants to be in an unbroken relationship – that’s why He forgives a repentance heart as yours clearly is.

  • Diane says:

    But itsmt that the same as cursing him. I promise I didn’t mean it. I didn’t mean to do it either.

  • Elkay Elkay says:

    Diane, the lead article assures you that “If you are worried that you have committed blasphemy against the Holy Spirit, you could not possibly have done it” so be at peace that you have not committed the unforgivable sin. Do continue to ask God for forgiveness if this happens again.

    Remember, the unforgivable sin is to witness God’s goodness in one form or another and calling it evil or giving Satan credit for God’s goodness’s and blessings (and continuing to do so). You did nothing like this . . . it sounds like you slipped up and mis-spoke and are convicted and are seeking forgiveness which God is faithful to do.

  • Diane says:

    I work for a company called Kirby. Ita door to door and the other day I was getting frustrated with my job and I began I pray and ask God to help me. I said “lord please help me get I to a house and then without thinking I took his name in vain. It’s eating me alive. Have I committed the unpardonable sin? Help me!

  • Sharon says:

    good article

  • Bernice says:

    I just would like this time to ask in hand that god is my life and I’ve turned my life to him he’s god he’s all I have allways had

  • Elkay Elkay says:

    Brad, the lead article assures you that “If you are worried that you have committed blasphemy against the Holy Spirit, you could not possibly have done it” so be at peace that you have not committed the unforgivable sin. Do continue to ask God for forgiveness if this happens again.

    Here’s the deal: what comes into our mind greatly affects what comes back out of our mind and we live in a world today that is saturated with ungodly images, songs, advertisements, Hollywood-heroes and more. Instead, Scripture tells us to “fix our thoughts on what is true, and honorable, and right, and pure, and lovely, and admirable. Think about things that are excellent and worthy of praise. Then the God of peace will be with us (Phil 4:8f).

    Brad, examine what is coming into your mind, your life, and if anything would be unpleasing to Jesus (things which promote sensuality, greed, sexual impurity, crude language, violence, hatred, love of self, or anything else not praiseworthy), then put it away from you. Spend time reading Scripture (especially Psalms), listening to God-honoring hymns of faith, reading about the lives of great Christians down through the ages, listening to Christian sermons on the web, etc.

    Here’s a popular antidote: a Christian was explaining to a missionary named Paul that the battle inside of him was like a black dog fighting a white dog. “Which dog wins?” asked the missionary. “The one I feed the most,” replied the Christian. Paul says, “Feed your mind on the pure truth of God’s Word.”

    Brad, with God’s help, that’s how you can win your battle against the satanic things of this world! Just ask Him early on every day and trust Him to help you.
