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.
Blasphemy against the Holy Spirit is The Unforgivable Sin and confirming this takes you to “blasphemia” in the Greek Manuscripts:
blasphemia, Greek 989 (blasphemos); vilification (especially against God) :- blasphemy, evil speaking, Railing.
Webster’s helps you understand “blasphemia” by defining “vilification”; it gives the components of this sin:
1: the act of vilifying: ABUSE
2: an instance of vilifying: defamatory utterance
You can easily see that blaspheming God is abusing and defaming Him.
Returning to the Manuscripts, “blapto”, blasphemies prime verb, shows “God being hurt” added to abusing and defaming:
blapto; a primary verb; properly to hinder,
i.e. (by implication) to injure :- hurt.
Understanding blaspheming enables you to understand that The Unforgivable Sin is to worship Satan in the place of God; surely you recognize that nothing could be more defaming or hurting. Your house being spoiled, illustrated in Matthew 12:29 KJV, diagrams worshipping Satan as The Unforgivable Sin:
Or else how can one enter into a strong man's house, and spoil his goods, except he first bind the strong man? and then he will spoil his house.
Matthew is drawing you a picture of blaspheming by illustrating Satan appealing to you (a strong man’s house) and you receiving him as Christ (him binding you). You, your goods, and your house become spoiled; Matthew 12:30 KJV continues:
He that is not with me is against me; and he that gathereth not with me scattereth abroad.
“Scattereth abroad” is a permanent separation from God and it is what takes place to anyone that commits The Unforgivable Sin.
Taking place during the five months prior to Christ returning, blaspheming requires that you:
 Receive and worship Satan and
