The Book of Revelations moves very quickly, but it spans for generations until it doesn't. it is compressed yet detailed in what we need to take away from it. Especially the Seven Churches. So, for me, I believe it's important to 1) know beyond a shadow of doubt which church the Lord sees me in, and 2) avoid doing anything that will cause my name to be dabbed out of the Book of Life, which tells me that once saved IS NOT always saved, and I don't want to get to the end with this being my learning curve.
