Of course not. I am not even positive that Jesus was telling the Pharisees right away that they had already committed the unpardonable sin, but rather I believe it possible that He was warning them that they were
close to doing so if they continued in their line of thinking (otherwise, if the Pharisees had already gone beyond any forgiveness from Christ, then I don't see why they would care if they had, thus why would Jesus even bother to tell them they had committed it in the first place? But that is just my speculation). So why would God condemn you for having thoughts that you do not even want? (And take heed, Eso, now that I have brought this up your mind may very well get so screwed up from the mere suggestion of what I just said that it might start telling you that you
do want these particular thoughts, or that you
do actually believe Jesus was casting out demons by the power of Satan rather than the good Holy Spirit. And if it makes you more afraid of having gone to a point of unforgiveness by merely having the thought, then of course the thought will persist and only torment you further.) So please try your best not to take stock in the bad thoughts, or even entertain the idea that these bad thoughts are the "true" you. Just try to ignore them and not get anxious. Again, does God take offense at every little thing the human mortal so far below Him does or thinks without His judging the human heart? No. He knows better than you do.
And I sincerely doubt He is the kind of God who will condemn a man anyway when that man
does not want to hate Him or abandon Him, when that man is in distress at the thought of being estranged from God. I know of no such God in my time. Because if God were like that? I doubt He would even have cared enough about humans in the first place to send His own Son to die a painful and brutal death for our sins.
If you try to follow the practical advice I gave earlier about just trying to let the thoughts ride out whenever they come instead of going through a compulsive ritual of trying to pray them away in distress, God will know that it is not because you like the thoughts and welcome them, even you may feel and wonder sometimes that you do.
Of course you don't like them or believe them. He knows you are just trying to find healing from them.
