In my own study I am exploring the idea of purification by fire. In this system of thought, hell is not a torture device but instead a surgical device.
It is temporary and purposeful for reparing a soul. As radiation therapy is painful but healing, hells fire is painful but merciful. It will result in something being burned out of the person that stands in the way of faith and surrender and worship. It is not redemption, but the cultivation for the necessary heart conditions that preceed redemption. As a tumor on the brain could impair a mind and cause them to be angry and devilish and ruin thier relationships, so the sinful state has ruined our relationship with God. The fire does not save us, but simply removes the tumor that has affected our judgement towards the one who loves us.
That said, it would seem that Jesus warning against the blasphemy against the Holy Spirit is not so hopeless after all.
First we have to remember that no one who goes to hell has been forgiven. Thats why they are there. So if the judgement of hell is in an age to come and the blasphemy in question gaurantees the guilty party will enter into that age of punishment, the question is not that they can never be saved. Jesus did not say they cannot be saved. He said they cannot be forgiven in this age or in the next age. Which leads us to conclude if that in this life they have crossed a line of seared conscience and depravity to commit such a sin, that they are reprobate and no reform of thier soul is possible outside of hellfire. Thats all Jesus is saying.
We are so conditioned to assume the permanance of hell by traditional doctrine that it requires a constant reminder that Jesus did not say it was forever or that they can never be saved. Instead he treated it as something undesirable and clearly something all should seek to avoid.
So all Jesus seems to be saying is that if they commit this sin, they are going to hell and theres no ifs and or buts about it.
And in saying that it wont be forgiven, my mind goes to the child who suddenly realizes he is going to have his butt busted in an epic way because he crossed a terrible behavioral line and he suddenly screams in repentance all the way to the paddling room. But no forgiveness is afforded. The behavior indicates a corruption that must be remedied by pain. That is to say no begging or pleading is going to prevent the punishment from being carried out. Sometimes kids can apologize their way out of a spanking. Jesus is just saying if someone commits this blasphemy theres no apologizing their way out of it. They have proven they need the treatment of hellfire as tragic as that is, because they have gone so far into depravity.
Lets face it Jesus ministry was all about rescuing people from the punishment of hell as well as reconciling them to God. Hell may not be permanent, but a God of mercy is so grieved by its pain that he made an infinitely more generous way to be reconciled to Himself. And even with the treatement of hell there will come an age in which those who have suffered its fire will see with new eyes and thank God for his discipline and turn to Christ as the one who died on the cross for them.
Those who commit the BATHS are simply being told they will be guaranteed hellfire due to the acute evil condition that sin is symptomatic of.
