In chapters 2 and 3 we find the revelation of Jesus Christ given to the 7 churches in Asia, these 7 churches are mentioned by name in Revelation 1:11. The apostle John was familiar with these 7 churches and therefore were physically existing churches. Each church had its specific problems. Some commentators claim that the description of the first six churches has already passed in the past two centuries. The last church presents the one we live in today. I personally disagree. These 7 churches are a clear picture of the different believers through the past two centuries and today of all believers individually.
