Urgh! christians vs atheists?

I choose not to debate or argue any theological point. Young christians especially like to argue, or at least overly enthusiastic in their presentation of the gospel message. This is something that changes as they mature. Yes, I do get tired of the same questions sometimes. But then, a kind response is often the message that does get through to the asker. I've heard it a lot: A christians life is often the only Bible some people ever read, and I'm sorry to say many have stared the reading but decided not to finish the book because the cover was dirty, or it was inconsistent with the title of "christian"...ie, "little christ."
