Why be good?

[JuliaL]

.. Search the scriptures to see if I'm quoting out of context.

Have you ever found even one atheist who was primarily concerned with the accuracy of scripture?  Weird.

Well, I am.  Were they an accurate reflection of reality, they would be critical to my primary goals-- to avoid suffering, specially my suffering.
It's just that I find the proposition that the scriptures are a collection of bronze age tribal histories and mythical tales of greatness much more plausible than the one where it contains distilled truth from some ultimate supernatural being.

The unforgivable sin refers to the obstinate refusal to accept the promptings of the Holy Spirit to seek forgiveness from God. If someone dies in that condition - unrepentant, defiant - then how would God forgive them without abusing their free will?

I don't see how one can refuse to accept the promptings of an omnipotent being.
Are the promptings not sincere?  Holy S. doesn't really mean them?
Or is It intentionally applying less than the necessary amount of convincing?
How can an omnipotent being get anything less than exactly what It wants?
