There are so many who trumpet the name of Jesus but don't really know Him. Like you, I always feel wary of those who try to force God into the conversation. I live in a city where many huge Christian organizations are headquartered, and many of those whom I've encountered from said organizations do not exemplify Christ/ are fairly nasty people. "They will know we are Christians by our love," not by our words--I don't avoid talking about Jesus if someone has questions, but mostly, I try not to pay Him lip service & pray my actions exude who I believe Him to be...I'm so sorry about the rock wall dude, but glad you're moving on from it too!
