Inspired means just that--inspired...God-breathed. Not "inerrant"--which I see as a claim that was part of a 19th century reaction to the extremes of the Enlightenment. This term didn't exist before the Enlightenment. I think many folks have confused facts with truth...that is, "if it's not factual, it's not really true" (or God-inspired).
From what I can tell, people in the ancient world that produced the Bible didn't share the same concern for factual veracity that we did, but felt it perfectly permissable to play loose with facts in order to accomplish their agenda in writing. A concern/value for facts is a product of Enlightenment thinking. The irony is that the same people who reacted against Enlightenment thinking have bought in to the "truth as facts" logic in coming up with and embracing the claims of inerrancy.
Plus, I don't feel the need to commit intellectual suicide or do mental gymnastics to be a faithful Christian--I see too many instances of biblical error to buy in to inerrancy. This doesn't bother me at all, though, since, just as I or any other preacher in a Sunday morning service can be "errant" and still proclaim the Word of God for our audience, so can the biblical witness be errant and still be the Word of God. To be human is to be with error; our merciful God elected to incarnate his Word in very human beings, in order to "reconcile the world to himself." "Inspired by God" doesn't have to mean perfect; "God-breathed" simply means God is at work in and through it. The Bible itself makes no claims of inerrancy, by the way...because it's a pre-enlightenment collection of books!
As for my discomfort (as you put it) with definitive statements about stuff like hell, that's simply part of a hesitance to participate in truth-claims that I view as arrogant, that I believe have a growing irrelevance for many people, and that I'm convinced have undermined the ability of many to comprehend the actual meaning of the Scriptures. As for sins, I don't have any problem talking about sins as sins; I just don't want to participate in getting overly focused on what I consider to be the symptoms of the fundamental problem: our state of alienation from God. To me, the gospel of justification/ reconciliation through Christ is God's healing remedy for the condition of sin, and as we claim this remedy daily and let God's Spirit do its work on our hearts and minds through both inner and external processes, we can see some change in/relief from the symptoms--although never anywhere close to a complete cessation, since the condition of sin is lifelong even when we make use of the remedy. Thank God for the remedy, though, since with it we can experience the blessedness of walking with God even when we suffer the consequences of sins--ours and other peoples'.
What can we trust? The promises of God, that call our faith into being and lead us into a right relationship with God through faith--not faith in facts but in the reality of God and the dynamic truth of a relational God--a living reality that meets us where we're at, not a collection of facts to be mined out of the Bible and boiled down to doctrines. Ultimately, we can trust in God--the God who, with all their foibles and discrepencies, the books of the Bible bear witness to.
Please know that for me, in no way does not accepting the factuality of many Bible passages make it any less valuable...it simply leads me to be much more cautious in making truth claims and endorsing doctrines. To say the Bible has errors doesn't make it an untrustworthy document; it makes it a document we need to make use of a lot less arrogantly than we often do! For me, the main function of Scripture is to bear witness to Christ; it's not the only witness we have, and so I don't need to depend on it as perhaps many of my fundamentalist brethren seem to think they need to. In addition to the Scriptures, we also have our own witness to the Living Christ, as well as the witness of 2,000 years of other believers--empowered by the gifts and presence of God's Holy Spirit in and among us, who is still inspiring and breathing today just as in those biblical writers.
In addition, to me it often seems the fundamentalist approach to the Bible leads folks to witness to and emphasize many things other than Christ...like all kinds of peripheral doctrines and moral claims that are not essential to and often interfere with promoting faith in the Living Christ. Not that non-fundamentalist folks don't have their own problems this way...we're all sinners--broken people whose approach to faith and it's vocations are stained by our sinful condition--leading us to commit sins of ommision and commision in the way we witness to our faith!
Well, you asked:)
