What is the purpose of the refining fire?

why is it so difficult at times when even when you "know" something it doesn't necessarily become true right away? the thing is from my perspective may be different than yours, as man fails god, while god fails god. i can't say for sure i understand subtleties from the opposite perspective... i do know this, many may consider me to be so foolish that they have be turned against me. all are equal in the kingdom of heaven. i marvelled at many of the people on here because i could tell by what they said that they already had natural wisdom. this would be the likes of Just Be, Blue Boots, Seth, Kar... Knows, Bilbo Baggins, Barf and many others. here is the thing, you may think badly of yourselves, this may be because you have yet to understand perfection. there are separate paths that lead to perfection, and any one of you may be perfect from god's perspective. it is written of job that he "always did what he thought was right". this may even be that when he was separated from god (not constantly thinking about it) he was still doing what he thought was right. man's judgment is much more harsh than god's. another example would be elijah, who was righteous in the eyes of god. this was partially because elijah said "for i am no better than my fathers."
