This book makes us concious of how easy it is to deny the faith without knowing it. The Bible instructs us to watch and pray that we fall not into temptation. This in itself implies that we have to know how temptation comes. To derail, there must be causes and processes and if one is not wary enough, it is quite easy to cross to the other side. This book helps us to know and be reminded of the causes and processes through which a believer can become an apostate without knowing it and how to avoid such.
