My points remain above, about how once we have accepted Christ we don't need to fear. People too often fear that if they slip up, they lose their salvation. I don't agree with that. Not b/c of some "once saved, always saved" doctrine but b/c God promises to forgive and nothing in Scripture supports that kind of "lose fear". IMO it goes against God's character and nature. I think if a person is worried, that is a good thing b/c it shows the Holy Spirit is speaking to their heart so really they have no need to b/c the Holy Spirit would not be there to convict their hearts if they were not saved anymore. Typically the one who commits blaspheme of the Holy Spirit and is not saved (either if they were previously or not) will not fear and have that conviction. I still hold that it is unnecessary to fear hell as a believer, unless you (general) are actively, intentionally rebelling, in a stubborn way, continually resisting, rejecting and insulting the Holy Spirit's work in your heart.
I've heard different versions of "blaspheming the Holy Spirit" that run anywhere from 'anyone who stops believing is a blasphemer to a more recent take that this sin only applied during the time of Pentacost, when the Holy Spirit was active in the world. The second version takes this issue out of play completely, the first version was used as blackmail to stiffle questioning and doubt.
From my perspective, these aren't real issues anyway, because I don't believe heaven and hell are possible because everything that makes us human and conscious, is physical and does not exist as any sort of unified pattern after death. I believe the growing body of scientific evidence confirms a suspicion that many mystics have had for centuries - that our understanding of our inner nature (an ego, or a unified mind directing the body) is false.
The mind is an impermanent cascade of mental states which can change throughout our lives. We think we are the same people we were 5, 10, or 20 years ago because that is what the brain-generated sense of mind informs us about ourselves; but if the physical processes going on in the brain change significantly, the changes to our outward personality may be significant enough to be noticed by others.
Ultimately, it's these reasons why I cannot accept concepts of absolute judgment - either reward or punishment - for the things people do in their lives. How we think, how we act, and how we form our beliefs is inextricably connected with the genetic and environmental factors that made us the way we are. Assigning an ultimate judgment on people for how they act or what they believe in, cannot be ethical.
When it comes to the way things are in this world - we have to apply limited judgment, and I would argue - limited rewards as well, because we live in a world where we have to encourage people to act better and discourage harmful behaviour, and remove the really dangerous people who cannot be rehabilitated in any meaningful way. Someone who is psychopathic, and unable to process the emotional feedback that most of us get, may not have a choice about their disorder, but if they are prone to violence, they have to be locked away from the rest of society....but, I don't believe they should spend eternity in hell afterwards, regardless of which criminal we're talking about. The concepts of free will have wreaked havoc with the justice system, by basing a punishment system on revenge and retribution.
