Since people in the Group found this helpful in dealing with the Unforgivable Sin, I thought I'd post it here.
1. Blasphemy, by its very definition, must be spoken out
loud. "Blasphemous thoughts" are thoughts that would be blasphemy if uttered. No matter how nasty a thought may be, thoughts cannot be blasphemy unless they are uttered. Even if the thoughts somehow could be blasphemy,...
2..... Jesus says in the very statement in which He speaks of the Unpardonable Sin that ALL blasphemies will be forgiven, whatever their content- but that THE blasphemy against the Holy Spirit will not be. It is obvious from this that since THE blasphemy against the Holy Spirit is not included in "ALL blasphemies," it must be something very different from merely saying something nasty about God (again, thinking something nasty about God, if it is not uttered out loud, cannot be blasphemy in the first place). It is unique.
3. Since Jesus says categorically that He will never, under any circumstances (the Greek says mh ouk, an intensifier that means "No way, Jose!") cast out anyone who comes to Him, it is obvious that nothing that does not prevent a person from wanting to come to Jesus can be the unforgivable sin.
4. It follows from that that a person who wants to be forgiven cannot have committed the unpardonable sin. If you recall, Hebrews makes that very point: a person who has committed the unforgivable sin cannot be restored to repentance.
5. In any event, "pop up" thoughts are not sins of any kind, which means that regardless of their content, they do not need forgiveness. And it is in the nature of OCD that if we fear that "pop up" thoughts come from us, it will "feel" to us like they do. That does not change the fact that if we hate the thought, it either a) is an OCD thought, in which case it is not even a sin; or b) since we hate and fear the thought, we have repented, cannot have committed the unpardonable sin, and are forgiven.
I'm afraid you just can't get around it. Even if a thought you hate or that you wish you hadn't had is sinful, no matter what the origin, all you have to do is to accept Jesus's forgiveness and you have nothing to be afraid of. You have repented. Then, whatever else may happen, you may be certain, first, that you have not committed the unpardonable sin; and secondly, that you are forgiven.
If its OCD, it's not a sin; if it's a sin, it's forgiven- and if you hate the thought, that is proof that you have not committed the unpardonable sin.
Any way you look at it, if you're worried about having committed the Unforgivable Sin, you have no reason to be.
