That's the problem. Most times when folks make such a charge, they don't think it applies to themselves. The lenses through which people view Scripture are necessarily limiting.
But then again, I don't like to be too hard on folks (and I'm not saying you or anyone else are, Erose). I am just concerned that some folks - if they take off their current lenses and try on lots of different ones in search of TRUTH - well, you never know the makeup of someone's faith. There are some folks who could be damaged by that.
And while I'm not God, and I can't know His judgement, I'm less inclined to think that having ALL the right answers just-so is as important as having a true faith and right heart. What I mean by that is that I'm not sure if a person might not be in danger by having false beliefs. Maybe they are. So if we ever have a chance to help in any way, I think it's our duty to do so. BUT - I am pretty sure it's possible to have every bit of correct knowledge regarding one's theology, and yet have a wrong heart (pride, unforgiveness, what-have-you) and be in serious danger at judgement. This is one reason I put spiritual well-being above argumentativeness.
Some people's faith could be shipwrecked by having their errors proven at a certain point of weakness. I don't want to be responsible before God for that! I think gentleness is less likely to have that effect. God protects and guides us all, if we let Him.
Sorry - I seem to be taking this in a different direction than I'd intended. Combination of recent conversations, recent experiences, and recent reading. I'm still trying to consolidate some things myself. Forgive me please.
