I think there is only one unforgivable sin: A person commits it when he defiantly refuses the Holy Spirit for all time.
Numbers 15 (NIV):
Sinning defiantly is associated with blaspheming the LORD. It is a person who hardens his heart against the LORD. It foreshadows Jesus' concept of blasphemy against the Holy Spirit.
Some scribes were defiant despite Jesus' patience with them.
Luke 12:
Matthew 12:
What is blasphemy against the Holy Spirit that will never be forgiven?
1 John 1:
If you confess, then this is proof that you have not committed the unforgivable sin.
How to logically unify Luke 12:10 (Matthew 12:31) and 1 John 1:9?
One way to do it is as follows:
Let P1 = the person who has blasphemed against the Holy Spirit.
This is a sin that P1 refuses to see as a sin. P1 has a hardness of heart. He stubbornly, persistently, and permanently refuses to repent for all time. He will never ask God to forgive him.
As Christians, we do not need to
fear. Whether or not you think you have blasphemed against the Holy Spirit, humble yourself before God and He will forgive you all kinds of sins and blasphemies.
For a specific example of blasphemy against the Holy Spirit, see
Whoever speaks against the Holy Spirit will NOT be forgiven.
Matthew 12:31
Wherefore I say unto you, All manner of sin and
blasphemy shall be forgiven unto men: but the
blasphemy against the Holy Ghost shall not be forgiven unto men.
Well, its not the hardening of the heart as the lord can change that as we see time and time again, but it is the attributing what is of God to evil or in this case to Beelzebub, which is Satan.
Matthew 12:10-24
10 And, behold, there was a man which had his hand withered. And they asked him, saying, Is it lawful to heal on the sabbath days? that they might accuse him.
11 And he said unto them, What man shall there be among you, that shall have one sheep, and if it fall into a pit on the sabbath day, will he not lay hold on it, and lift it out?
12 How much then is a man better than a sheep? Wherefore it is lawful to do well on the sabbath days.
13 Then saith he to the man, Stretch forth thine hand. And he stretched it forth; and it was restored whole, like as the other.
14 Then the Pharisees went out, and held a council against him, how they might destroy him.
15 But when Jesus knew it, he withdrew himself from thence: and great multitudes followed him, and he healed them all;
16 And charged them that they should not make him known:
17 That it might be fulfilled which was spoken by Esaias the prophet, saying,
18 Behold my servant, whom I have chosen; my beloved, in whom my soul is well pleased: I will put my spirit upon him, and he shall shew judgment to the Gentiles.
19 He shall not strive, nor cry; neither shall any man hear his voice in the streets.
20 A bruised reed shall he not break, and smoking flax shall he not quench, till he send forth judgment unto victory.
21 And in his name shall the Gentiles trust.
22 Then was brought unto him one possessed with a devil, blind, and dumb: and he healed him, insomuch that the blind and dumb both spake and saw.
23 And all the people were amazed, and said, Is not this the son of David?
24 But when the Pharisees heard it, they said, This fellow doth not cast out devils, but by Beelzebub the prince of the devils.
The Pharisees see that Jesus has just healed a man with a withered hand and now onw possessed by demons, and many people who saw the healings were thinking that He must therefore be the Christ. Compare verse 23 to a few others in Matthew
Matthew 9:27
And when Jesus departed thence, two blind men followed him, crying, and saying, Thou
son of David, have mercy on us.
Matthew 21:9
And the multitudes that went before, and that followed, cried, saying, Hosanna to the
son of David: Blessed is he that cometh in the name
of the Lord; Hosanna in the highest.
So the Pharisees attribute Jesus' ability to exorcise demons to Beelzebul, that is, Satan as you see in verse 24 .Their claim is rebuked by Christ as He notes that the Holy Spirit is behind His power.
Matthew 12:25-28
25 And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand:
26 And if Satan cast out Satan, he is divided against himself; how shall then his kingdom stand?
27 And if I by Beelzebub cast out devils, by whom do your children cast them out? therefore they shall be your judges.
28 But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you.
By the Holy Spirit He casts out demons, and then Christ teaches on the blasphemy of the Spirit, thereby indicating that it consists of attributing demonic activity to Jesus.
Matthew 12:31-32
31 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.
32 And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
