I hear about this all the time in church. Our pastor tells the story about a man named, Alex McFarland, who wrote a book, "10 Answers for Skeptics," http://www.amazon.com/Answers-Skeptics-Alex-McFarland-M-A/dp/0830758739. It's about his discussions with atheist or agnostics and found that the majority of them had strong Christian backgrounds, like their parents were ministers, and they were so strongly affected by the hypocracy and whatever that they moved in the polar opposite direction. Do we as zealous christians offend or hurt other christians. Or equally terrible, do we offend or hurt those whom we are trying to share our gospel? Do we aid the devil and tighten his hold on these people?
Read this article and let's sit on the porch and talk about it.
