Brief Thoughts on "The Will of God"

She has a very good point.... 
When anyone (my past self included) presumes to know the will of God - be it from a sudden realization, from a passage of Scripture they read, whatever - their knowledge is tainted by their personal views, desires, experiences. So, what is the difference here between Christians and non-Christians? Non-Christians have sudden epiphanies and then tell people, "Hey! I just had a great idea! I've been thinking about this for awhile, and after a lot of research, counsel, and trouble-shooting, I now know what I should do." Christians have the same epiphany experience and tell people, "Hey! Guess what God showed me today! Yup, He definitely revealed His will to me. Praise God for showing a sinner like me what He wants for my life!"
It's not that they have a very different experience, just that one person has the guts to take responsibility for their work and ideas while the other group claims it's divinely inspired and now a holy quest. Conversely, when the non-Christian discovers he/she was wrong about the former decision/action, they can take responsibility for the mistake and change the course of action. If the Christian feels he/she was in the wrong, either they must think God had a bad idea (blasphemy!) or His once-so-clear guiding was grossly misunderstood, and if the Christian so grossly misunderstood things, well, he must be "living in sin" or something, right? 
Personally, in my past, I would read through the Bible regularly, study it through outside writing about it, and pray to God every day - I wanted to know His will. As I read and prayed, I thought about everything I saw and felt, and from those experiences I drew conclusions about what was the right thing to do, and considered it to be God's will. Then later on down the road, when I realized that my original conclusion was wrong, I would feel confused (it had been so clear before, and that was what Scripture had said) and then feel a sense of guilt for being such a sinful idiot for misunderstanding things. After all, God wasn't cruel and vindictive enough to lead me on or hide His perfect will from one of His children... was He? If I sought Him earnestly and did as His Bible told me to do, was I not following Him and considered to be His child? Consider this passage:

Does Belief Matter?

What makes a religion, or any other belief, good or valid?
People of all faiths can talk about their experiences, the good feeling or peace that their beliefs bring them. So, the question that always bugged me is: Are all of the experiences, emotions, whatever that people have valid, or is only set's real? Christians claim to be the only truth in the world, and other religions make similar claims. If only one set of beliefs is the truth, then the experiences of everyone else must be invalid. To a Bible-believing Christian, the happiness of the Buddhist or Muslim is somehow fake, because the only "true" happiness is found in Christ. The followers of Christ should, by default, be the happiest people in the world. All of their problems are simply explained as happening in order to bring glory to God, right? Then Christians should welcome their every trial and tribulation as just another opportunity to bring God glory. People with chronic illnesses and debilitating conditions should just accept them with joy, since they have such a great opportunity to bring glory to their God. Their beliefs sustain them, and are the source of their happiness. Everyone else in the world has beliefs, and their beliefs also bring them happiness and fulfillment. But, only one set's happiness and fulfillment is real... or is that just an exclusionary lie? Is the rest of the world simply faking their happiness and fulfillment? Or, horror-of-horrors, could be it be true that all beliefs are valid, in the sense of bringing the believer happiness and personal fulfillment (along with all the emotions and experiences associated with "discovering the truth")? Is all truth set in stone, or can it be relative? History is full of people who found joy and contentment in believing what we now know to be lies. Was their joy lesser than anyone else's?
It seems to come down to the act of believing in something, rather than what that something is or isn't, is what brings fulfillment and joy in one's life.
