What are you changing your mind about? What are you rethinking, reconsidering, re-viewing (seeing again, possibly from a different perspective)? This is not a right/wrong question--NOT what were you wrong about that you have now "seen the light on" and made right?--but what are you rethinking, and why?
My personal example (at least one of 'em): I'm re-thinking the whole "role of women" question and find myself moving towards a somewhat more "egalitarian" position. And I haven't worked it all out. I continue to believe that there are fundamental, God-ordained differences between men and women, but am less sure that that matters as much in terms of the roles people play in the life and work of the church. What's pushed me in this direction is a continuing conversation within our own church, and some reading that I've done. I'm sure as well that my culture is impinging on my thought processes!
A second example has to do with evolution. Actually, that's probably not the right way to put it. I think what I'm rethinking is the ways in which science (a form of "general revelation") and faith ("special revelation") interact. If, for example, the evidence supporting evolution is increasingly compelling (and I think it is), how do I respond to that in/by faith? I haven't worked this one all out either!
The point here is NOT to debate these particular issues (although I'm happy to hear from you on them), but instead to invite us to discuss ways in which we see ourselves changing.
Change is not automatically good, of course: forward steps, backwards steps, and steps off the cliff are all forms of "change"! Your rethinkings do not need to be limited to intellctual or theological issues (as my two examples tended to be)--you may be rethinking prayer, church (as we've already been discussing), or almost anything else. And you don't need to have it all worked through. And there's nothing to say that your reconsideration process won't eventually lead you to reaffirm what you've previously held to. But whatever you may find yourself reconsidering, I'd be interested in hearing about it!
