I often wonder that myself, especially after studying the meanings of the greek and hebrew.
I also wonder when it comes to the rapture, why God would suddenly rapture us with no pre-warning etc. That would cause such chaos, and death. I just don't think God would cause that by the rapture. I believe that He would give signs and do it with the least amount of tragedy!
This might spark a debate...I don't mean to do that just sharing some of my random thoughts.
