I'm sorry to burst your bubble but Scripture declares the "unpardonable, unforgivable " sin is the blasphemy of the Holy Spirit not unbelief.!
Let me help you..
What you are talking about is blasphemy OF....the HS..= the Unpardonable sin, which is what the unsaved Jews were doing in Hebrews 10.....
THey were blaspheming and they were unbelieving.
Speaking against the HS, is blasphemy AGAINST....and Christ Rejection is also the same sin, but it a different technique... its Blasphemy OF..
Same end result. = Hell.
Think of it like this...
A person is drawn....compelled.......wooed, by the Holy Spirit to accept Christ when they HEAR the Gospel.
"faith comes by HEARING"......the word of God......which is a living seed, and not just text on paper in a bible.
So, an example of refusing the Holy Spirit, which is to blaspheme and to reject, is this...
A person is a solid church member. 40 yrs.
For 40 yrs, during the Alter Call, on Sunday, they stand and RESIST being born again.
THey RESIST the Holy Spirit's drawing them to the Cross, leading them to The Christ.
They RESIST the HS for 40 yrs.
This is committing the unpardonable sin. You find Hebrews doing this, in Hebrews 10.
This is John 3:36
When Jesus walked the earth, you had Hebrews who accused Him to His FACE of doing Miracles "by the power of Satan"....and this is Blasphemy AGAINST the Holy Spirit.
So, you have blasphemy OF, which is to reject Jesus, and die a Christ Rejector, = the unpardonable sin
You have blasphemy AGAINST the HS< which is to speak to Jesus, to His FACE, accusing Him of Satan's Work.
