The unforgivable sin

[Carbon]

The unforgivable sin - Blasphemy against the Holy Spirit.

Matthew 12:24-37​

English Standard Version

Chapter 12​

24But when the Pharisees heard it, they said, "It is only by Beelzebul, the prince of demons, that this man casts out demons." 25Knowing their thoughts, he said to them, "Every kingdom divided against itself is laid waste, and no city or house divided against itself will stand. 26And if Satan casts out Satan, he is divided against himself. How then will his kingdom stand? 27And if I cast out demons by Beelzebul, by whom do your sons cast them out? Therefore they will be your judges. 28But if it is by the Spirit of God that I cast out demons, then the kingdom of God has come upon you. 29Or how can someone enter a strong man 's house and plunder his goods, unless he first binds the strong man? Then indeed he may plunder his house. 30Whoever is not with me is against me, and whoever does not gather with me scatters. 31Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven. 32And whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.
33"Either make the tree good and its fruit good, or make the tree bad and its fruit bad, for the tree is known by its fruit. 34You brood of vipers! How can you speak good, when you are evil? For out of the abundance of the heart the mouth speaks. 35The good person out of his good treasure brings forth good, and the evil person out of his evil treasure brings forth evil. 36I tell you, on the day of judgment people will give account for every careless word they speak, 37for by your words you will be justified, and by your words you will be condemned."


So, my question is: what exactly is the unforgivable sin?

So, my question is: what exactly is the unforgivable sin?

Given the context. I would say attributing the works of Christ to Satan. The works that Christ did were by the working of the Holy Spirit in him (Luke 1:35; Is 11:2; Luke 3:21-22; Heb9:14 etc).

And it is the Holy Spirit who applies the work of Jesus to a person in regeneration.
