Check out this post on Mark Riddle's blog.
It's a video of Randy Bonifield from Kansas City performing a song at his church. It's about how "Left Behind" eschatology had a frightening affect on him as a child. I thought this funny but serious song was a good critique because his experience is apparently similar to mine.
I grew up in one of those churches that believed in and heavily taught an eschatology that focused on the concept of "Rapture." As a kid, this really scared me and as a teenager I found myself embedded in a religion of fear. This can really mess people up. In fact, I had problems in my approach to Christianity because of this teaching for many years.
Watch the video and see what you think.
