@kellyjay saidWhy didn't Jesus arrange to have himself tortured in burning flames for eternity if that is, as you claim, the "just" price to pay for "sins"?
It is evil and righteousness; there will be no half and half, it will be one or the other among men, and that is found either in Jesus Christ our Savior, or us dying in our sins.
@kellyjay saidWhy is causing "suffering and pain" to non-believers the way to deal with "suffering and pain" caused by believers?
Then after evil is dealt with thoroughly, after it is totally revealed for what it is, and does. It will be removed from the Kingdom of God, never to cause suffering and pain again, you can be glad.
@rbhill saidYour conjecture about being "saved" and about "grace" are aspirations rather than "knowledge" of anything.
Knowledge doesn’t save. Grace is what saves.
If there is a creator, knowledge about its creation is being explored by scientists and not religionists.
The notions of "grace" and "salvation" and "immortality" are things you came across when you were contemplating your navel, whilst - perhaps subconsciously - seeking solace in the face of the inevitability of death.
@rbhill saidThe statement "Grace is what saves" provides some knowledge about what Christian doctrine says and also what kind of thoughts or hopes or personal opinions make you tick.
Knowledge doesn’t save. Grace is what saves.
The statement "Grace is what saves" does not provide any objective knowledge about the universe or about the being that created it, if there is one.
