The thing I am learning is this; when someone asks me a Q about my faith, I really have to ask myself "what is their motive in asking this?". If they are really interested in Christianity that is one thing but if they are just trying to tear down my faith or tell me how stupid it is, then what is the point in even addressing thier Q's.
If I am happy being a Christian then so be it. Why not just leave it alone. If someone else is happier not believing in a God then that is their perogative. I am not trying to convert anyone on this board to christianity and I can tell you right now, there is no way anyone is going to make me an athiest.
So again, I think we have to try to discern the persons motives in asking the Q. And if we think it is just to argue or rehash the same old thing all over again which there is no real answer anyway, because I can't prove 100% God exists to a nonbeliever and they cannot prove 100% God doesn't to me. So it is just an excercise in futility.
That is where the advice given here to just say "no thanks, I am not interested" is such good advice. And that goes both ways for those who believe and those who do not. Peace, Lilly
