The messages for the seven churches were for the churches in existance in John's day. But many hold that the messages given to them have application to us today. But how can we apply it to us? If we take that as the "type" for us we will see that each church was given a different message for the problems "it" had to overcome. And all the churches were in existance at the SAME TIME. Not one after another. Therefore, if they were in existance at the same time all with varying degrees of faith and problems, it would make sense that for us today to think that the same would apply in our time. We would see all these "types" of churches with varying degrees of problems in operation at the same time. And for those of us who have been in many churches, we understand this to be true.
The groups that teach we are in the last church age are the ones that also say their church is the only true one and thier messenger (Russell) is the Laodicean or 7th messenger. They simply are misaplying scripture. I believe the above interpretation is more likely correct but others may disagree. I will not go into why the 7th messenger view is wrong at this time.
Mary asked who is Babylon the Great? Good question.
Ancient Babylon was the political, commercial and religious center of the world empire. It was noted for many luxeries and its moral decadance. The title "Babylon the Great" is taken from Daniel 4:30. According to some it is used in Revelation for Rome because at the time of John's writing Revelation, Rome was the center for opposition to God and his people. The fact that Babylon in Revelation applies to Rome helps us understand why John wrote in signs and symbols - to hide his scathing message against Rome the world power at his time. Unlike some who teach the message in Revelation only applies to our day and was sealed up somehow until our time, I believe the early church understood John's revelation and knew it applied to Rome and most of it was fulfilled in Rome during John's day. (see Revelation 16:9, 17:5, 18:2, 10,21)
This "Babylon" was a "type" for a later time according to many. It will represent the whole political and religious system of the world in general under the future reign of the coming Antichrist and will persecute God's people terribly (the church). Much in the same way as the early church being persecuted under Rome's rule. This Babylon the Great is not in power yet but one thing is for sure, it is not one particular religion nor is it representative of Christendom as a whole. Again, we don't really know until it comes into power "what" it truly is. Hope this helps, Lilly
