God wants to forgive us, but we need to let Him. The only unforgivable sin is blasphemy against the Holy Spirit, which is to intentionally and consistently harden your heart and ignore Him-- how can you be forgiven if you ignore the one who wants to forgive you? If you’re wondering if you’ve done that and wether you can be forgiven, it’s not too late. You can still come back to Him.
I might not be understanding the nuances here, but from what you say even an Unforgivable Sin is “punished” by oblivion in the death-sleep, no?
So I gather then that you don’t really fear hell, although not-hell would be preferable?
