I love the dialogue, too.  Thanks for taking the time to share your thoughts.  I completely understand your points.  And you're absolutely correct that believers in Christ don't need to practice the things of unbelievers to create a comfortable environment. 

I think, for me, the challenge is, when attempting to lead unbelievers to God, how do we determine what is "glorifying" Him, in order to lead an unbeliever in the "right" direction.  Although scripture can clarify it to a degree, I say degree because it's still interpretation/translation/perspective/specific time in history, etc....and how that translates in today's world is not simple.  

I get so stumped by the awesome questions and rebuttal from non-believers that I end up saying, "I don't know the truth.  You don't know the truth.  Nobody truly knows the truth.  We can only have faith that what we're reading and researching was interpreted accurately and when in prayer with God, he will place the truth on your heart, mind, and soul.  Regardless of how strange it might be to believe certain stories in the Bible, I know for a fact, what I've experienced in my own life, God was there.  You will know it.  And if I'm wrong, I lost nothing.  If I choose a different belief system, I lose eternal life and much more."

(I've read many books that would be on the "bad" list of many other Christians.  And honestly, I wouldn't change that and I'm thankful I don't feel shame about it.  If it's impacted my life negatively, I haven't noticed.  I read my Bible just as much.  A part of me seems to enjoy the well-rounded perspective because I feel I can naturally engage a variety people with differing perspectives.  I suppose I look at it as research.)
