This book is a study of the first three chapters of the book of Revelation.
These chapters have a repeated call to those who want to be overcomes.
The first chapter describes a vision of the risen Lord. The next two chapters describe the Lord's evaluation of seven messengers and their churches in Asia Minor.
These messengers and churches are pictures of elders and churches that have been in existence in all these 20 centuries and that exist even today. Each of us who are elders can evaluate ourselves and see where we and our churches stand.
The Lord's evaluation of us and our church will be very different from our own and from that of others. Most of us have a far higher opinion of our spirituality that is actually true. If we are willing to be evaluated by the Lord now, and face up honestly to what He shows us about ourselves and our churches, we can be saved from a lot of sorrow and unhappiness when we stand before His judgement-seat in the final day.
