I am an open minded and curious person who is surrounded by people of different faiths. I guess it was only a matter of time before I started questioning why one set of beliefs was more justified to believe in then another. God has never appeared to me personally and told me what to believe but I've had plenty of PEOPLE try to tell me whats what. Why should I take one persons word over anothers when none of them can answer my questions with reasonable answers? But of course what I deem reasonable to me is my own personal opinion which can be and likely is flawed in some way. I am only human after all.
Well, I think that's a fair question - and a very sage response regarding the possibility your thoughts on the matter may contain certain flaws - or, as is probably more apt - that they just don't have the benefit of all the information at hand (something I continue to discover about my own opinions

).
"My faith" if you will, was a long journey - and for that matter still is. Like you, I can't listen to just anyone when it comes to matters of faith - I need the "right" explanations, explanations that address my issues and my needs - perhaps my personality too. I've been turned off by the outrageous emotionalism of - forgive me - "Jesus freaks" in my youth (the 60's), and televangelists waving green hankies for the supernatural benefits they might conjure up, by silken-voiced preachers, by namby-pamby men who speak wistfully and softly in a pseudo-theological whisper as if that's normal speach, by perfectly coiffed specimens of who-knows-what, by down-right kooks proclaiming Jesus, and miracles, and tongues, and riches beyond imagination, by out-and-out crooks whose only motive was money, and by complete sissies whose only redeeming qualities (in my eyes) was perhaps their sincerity.
One day in college I met an "average Joe" (his name was actually Kurt) who introduced me to some other "average Joes" and an average Joe church filled with normal people and normal issues, normal ideals, normal emotional makeups, normal interests, and normal values. They got me back into reading the bible for my answers - in an objective way, sans the emotional weirdness and subjectivism that still turns me off. I think for the first time in my life I could attach something spiritual and "of faith" to a human being like myself. No one "weirded me out." No one demanded anything of me but my questions; and no one expected anything of me but honest inquiry. I suppose for the first time in my life I was given sanction to actually read the bible like a normal human being. So I did.
I found, much to my amazement, being drawn to a "normal" explanation in the bible what God was like - truly like (contrary to all the oddities I'd experience till then). I found in the bible God revealing Himself to me - not all at once - a little here; a little there. I could ask questions of those I'd met in the church and they helped me, which I appreciated.
Have I ever "seen God?" No. Has God ever "spoken to me" as one man standing before another speaks? No. Has God ever brought thunder and lightning to bear in my walk with Him to demonstrate His reality? No. Has He ever filled me with ecstatic utterances and visions of supernatural glory? No. Has He ever filled my coffers with gold and gems, assuring me of financial security the rest of my life? No.
Has He answered my questions, my prayers? Yes. Was it with such clarity as to avoid being mistaken for chance or circumstance? Yes. Was it in such a way that others might doubt my claims? Sure. Was I tempted to doubt myself that it was indeed His answers? Yup. Did I ever or do I ever succumb to such temptations? Yes.
Do I believe myself a rational person? I do. Can I demonstrate unequivocally to others that God has indeed answered any of my questions or prayers? No. So I'll stop there; but, He did change me. I can't explain it; but He did change me. I'm not the same person I was before. I'm still afflicted with the same temptations, the same weaknesses, the same issues - but He did give me something even more precious (to me); He gave me the ability to say "no" and make it stick. He gave me of His values, which motivate me more and more to want to behave accordingly. Do I behave accordingly all the time? I wish I could say "yes," but I still stumble. Yet, He gave me the ability to say "I'm sorry" and mean it - to want to be like Him, despite the seemingly insurmountable distance between His character and mine.
Is there some mathematical or scientific explanation for the above? I suspect not. Does the above violate Newtonian or quantum law - maybe, though I don't see the necessary correlation. Would I even want there to be a Newtonian or quantum explanation for what changed in me? Somehow I think that would only diminish the wonderfulness of it all. Yet I remain one devoted to rational thought - go figure
I hope someday you find the answers you seek. I wish I had all the answers - the formula, the equation, the "universal theory" to explain God. Many Christians behave as if they do. Many Christians feel the need to explain something of which they only have the barest of actual knowledge. They're not "deluded" or "bad" people per se. We dogmatically produce verse after verse, scripture after scripture as if that were the panacea and solution to everyone's questions about Him. Understand though that in one sense, they're right - we're right insofar as we believe; it [the bible] is all we know about Him - all He's revealed to us. I believe it for the reasons I mentioned above - answered prayers and answered questions, among other things. I confess I used to bang it over people's heads in evangelistic fervor to get them to repent, confess, be baptized, etc. etc. etc.... But then I've had to have my own "come to Jesus" meetings over the years (or vice versa) - to remember and come to the realization that that's not what He did to me, or how He did it to me - been there, experienced that.

No, when I was ready, He saw it fit to introduce me to a couple people in my life who loved Him in a real way, who cared enough about the power of His word and His word alone to let it, rather than their zeal or fervor make the necessary changes in my heart.
We (Christians) make mistakes; whether from zeal or strength of belief, sometimes dogmatically, sometimes naively. I guess we're human like everyone else. We aren't always perfect articulators, orators, teachers, preachers - even examples. But most of us are sincere in our love for Him and our belief in Him - whether we can explain it or not; whether it sounds rational or not. Regardless, He is consistent in His love for us and if there's any "glue" holding all this together - that'd have to be it.
I guess for me, that's about as "reasonable" an answer as I can hope to give in such a venue as this.

God bless.
