I grew up in Knoxville, Tennessee, which meant that I had very few Mormon friends and many if not most of the people I went to school with were some kind of evangelical Christian. I often secretly envied them.
Even so the words and phrases they used to talk about their faith often really bugged me. It was so alien, and so off-putting.
Turns out those words and phrases were almost always actually from the Bible.

When I was growing up, I never really paid any attention to what anyone was saying about God.
But now, I pay a great deal of attention to what others say. I work with several Evangelical types, and I find myself reminding them that what they are saying, or what they are so often advocating, is not really in the Bible at all. Especially when they are on the ‘you need to make a decision for Christ’ kick. And “free-will” talk, and all that. Which is a big part of their belief system…and totally not biblical.
