Matthew 12:31-32 teaches about forgiveness and the unforgivable sin. What is this sin? How is it committed? And how can you know you have not committed it? These are the sorts of questions I attempt to answer in this study of Matthew 12:31-32.

The Unpardonable Sin in Matthew 12:31-32
Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men. Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come.

This passage contains information about the most-feared sin in all of Scripture: the sin of blasphemy against the Holy Spirit. I have written an entire book on this passage called (#AmazonAdLink) Why You Have Not Committed the Unforgivable Sin, and so will try to keep my comments about this text relatively brief.
The Most Common View about the Unforgivable Sin
Most discussions about the unforgivable sin focus on the nature of what this sin is, and how it can be avoided.
The difficulty with this approach is that while Jesus does talk about speaking against the Holy Spirit, He doesnโt explicitly state what words constitute blasphemy. Since the religious leaders in the preceding context accuse Jesus of casting out demons by Beelzebub (Matt 12:24), many assume that the sin of blasphemy against the Spirit is when someone attributes the work of the Holy Spirit to Satan (cf. Mark 3:28-30).
There are numerous problems with such a view, not least of which is the fact that Jesus is clearly providing a warning to the Pharisees that they were about to commit this sin.
In other words, they had not yet committed it, but if they continued on the path they were on, they might. So if they had not yet committed this sin, then this means that attributing the work of the Holy Spirit to Satan is not blasphemy against the Holy Spirit.
Besides, if it were, we would never be able to โtest the spiritsโ as John calls us to do (1 John 4:1), for we would be too fearful of blaspheming the Spirit to ever say that a certain work was not from God.
The Bible Doesn’t State what the Unforgivable Sin Actually IS
So the truth of the matter is that the Bible does not explicitly state what constitutes blasphemy against the Holy Spirit.
This is actually a good thing. Just as a sign that says, โDo not walk on the grassโ causes people to walk on the grass, if the Bible clearly stated what words constituted blasphemy against the Holy Spirit, this would only encourage people to say the words even more. So we donโt precisely know what this sin is.
Nevertheless, we do know a few things about the nature of this sin. One of the tasks of the Holy Spirit is to convict the world of sin, righteousness, and judgment (John 16:7-11). If a person says something vile and mean to the Holy Spirit or about the Holy Spirit, and then feels guilty or ashamed of what they have said, this is clear evidence that the Holy Spirit is still at work in their life convicting them of sin, righteousness, and judgment.
The fact that the Holy Spirit is still at work in their life indicates that the Spirit has not left or abandoned them, and therefore, they have not committed the unforgivable sin. In other words, those who fear that they have committed the unforgivable sin, thereby have evidence that they have not committed it. It is only those who have no shame or guilt about their words or actions who might possibly have committed this sin, yet they would never even know they have, because the Spirit is not at work in their life to convict them of sin.
All of this is discussed further in my book on the unforgivable sin.
Key Insight on the Unforgivable Sin: The TYPE of Forgiveness Jesus is Talking About
One of the things I also write about in that book, however, is something that is rarely discussed elsewhere in other books about the unforgivable sin. While most books focus only on what this sin is, few books discuss what type of forgiveness Jesus is talking about in this passage. Yet this is the crucial key which helps explain what Jesus is saying.
The word that is used for โforgivenessโ throughout this passage is aphฤsis. This means that whatever the sin of blasphemy against the Holy Spirit is, it also is under the charizomai forgiveness of God. In other words, whatever this sin is, it too is a sin that God has forgiven from eternity past (See the two types of forgiveness).
Remember, Godโs free charizomai forgiveness is based on His grace, and covers all sins of all people for all time, including the sin of blasphemy against the Holy Spirit. When this truth is recognized, we are then free to see that the text says nothing about God not forgiving those who commit this sin, but only that they will not receive aphฤsis, that is, they will not be released from this sin.
But since God has already freely forgiven (charizomai) them for this sin, then why do they not receive aphฤsis? Why are those people who commit this sin unable to find a release from it?
The answer is found in recalling that aphฤsis often has conditions attached to it, and if a person does not meet these conditions, then they are not released. While God wants the people who commit this sin to be released from it, they refuse or are unable to meet the conditions for the release of this sin, and so do not find any release from it. In other words, it is not God who is refusing to release them from this sin, but the people themselves who refuse to be released.
As explained by multiple texts elsewhere in the Bible, the release of aphฤsis begins within each individual person as they own up to what they did, repent of it, and forgive themselves for it. Finding release from sin is based on understanding that we have been freely forgiven by God, and so we too can freely forgive ourselves and others, and as a result of this free forgiveness, begin admit our failures and work to change the patterns that led to this sin in the first place.
But the person who never recognizes the truth about Godโs free forgiveness and how to break free from the bondage of sin in their life, will never find or experience forgiveness for themselves. They will remain โunreleased.โ
This passage is not talking about an โunforgivable sinโ but an โunreleasable sin.โ It occurs when a person does not release themselves.
All sins are forgiven by God, but if a person does not forgive and release themselves, there is nothing more God can do.
Why is It called Blasphemy Against the Holy Spirit?
This sin is called blasphemy against the Holy Spirit because it is refusing to believe what the Holy Spirit says to us about our sin, and instead believes the lies of Satan. The Holy Spirit is saying to each and every person, โYou have been freely forgiven! So live in light of that and be released from your enslavement to sin, shame, and guilt.โ
But the person who refuses to accept forgiveness and release is denying the testimony of the Holy Spirit, and is instead believing the testimony of Satan, the accuser. While the Holy Spirit says, โYou are forgiven!โ Satan constantly says, โYou are condemned!โ
As long as a person believes Satan over the Spirit, they will remain under condemnation (Mark 3:29). As long as a person believes the lies of condemnation, they will live unforgiven lives. They will continue to be enslaved to the deceptions of the devil and in bondage to the corruption of sin. They will never experience the release from the bondage of sin, shame, and guilt.

So What is the Unforgivable Sin?
To put it simply, the unforgivable sin is the sin of unforgiveness โฆ directed at ourselves.
A person commits this sin by refusing to believe the testimony of the Holy Spirit that they are completely accepted and forgiven by God. They remain unforgiven, or unreleased, because they donโt forgive themselves. The unforgivable sin is the sin for which a person denies and rejects that God has forgiven them, and thus, they continue to beat themselves up about it and suffer the consequences.
The point of Jesus in Matthew 12:31-32ย is that you canโt hang on to unforgiveness without paying a price. The only sin you are not forgiven for is the sin you donโt forgive yourself for. This state of refusing to accept the Spiritโs testimony about forgiveness only leads deeper into bondage and slavery to sin.
Jesus reveals that God has forgiven all people for all sins throughout all time. But if we believe the lie of the accuser and deny that we have been forgiven, then we will not believe we have been forgiven, and will continue to live a state of unforgiveness, as if we were eternally condemned.
So recognize that you have been forgiven for everything! Only when you do this will you be released from sin, shame, guilt, and fear, and will find true life in the Spirit that God wants for you.

First, whatever type of sins Paul has in mind, they do not appear to be of the sensual or sexual variety. When Paul writes that โwe all once conducted ourselvesโ in these behaviors, Paul includes himself as being guilty of these sins. But we know from passages like Philippians 3:3-6, Paul considered himself to be blameless in obedience to the Mosaic Law. He kept the purity laws to such a high degree, he was even able to become a Pharisee. It is unlikely, therefore, that Paul ever committed some of the sexual sins that many read into the text of Ephesians 2:3.
So if the application of Paulโs message in Ephesians 2 is that we should no longer kill and condemn others for religious reasons, but should love and live in unity with them instead, this means that the stated problem in Ephesians 2:1-3ย must refer to this sinful behavior as well.
There is no such thing as a “sin nature.” The Bible never refers to the “sin nature.” It is a myth of modern theology. However, the Bible DOES teach a lot about the “flesh.” This study looks at Galatians 5:19-23 to learn what the flesh actually is, and what we are to live in the Spirit rather than in the flesh.
The church in Galatia was divided over the issue of circumcision. Some argued that circumcision was required by God, while others said that it was not. Paul wrote to the Galatians to weigh in on this matter.

The carnal person, then, is the opposite of the spiritual person. The carnal person may appear to be quite โspiritualโ and religious, but they are unable to grasp, understand, or practice the greater truths of Christianity which lead us lay down our lives for others in love and service to them. The carnal, or fleshly person is not necessarily one who gives in to the passions and lusts of the flesh, but is rather one who thinks that the chills and thrills of ecstatic religion makes them superior to others.
It is indeed true that some of the Corinthian Christians were engaging in sinful sensuality (cf. 1 Corinthians 5:1; 6:9-10). But when Paul uses a word to describe this sort of behavior, he does not use the word โfleshโ to describe this behavior, but the word โunrighteousโ (1 Corinthians 6:9). Yes, fleshly, carnal thinking leads to unrighteous behavior, which is why Paul instructs the Corinthians to hand a man over to Satan for the destruction of his flesh (1 Corinthians 5:5; see Satan for a discussion of what this means).
