In His Olivet discourse, Jesus forewarns of certain events that would close out the church age: natural cataclysms, wars, civil strife, and perplexing problems. However, the most serious warning concerns deception. This warning is not to the world, but to the church. Jesus described this as so serious that if it were possible even those written in the book of life might be deceived. Even now there are many distorted sounds coming forth from the pulpit, and it is with this concern that we set forth this book. It is our earnest desire to impart some valid keys of discernment and hopefully save many from eternal ruin.
