The seven churches were located throughout Asia at that time (Physical location), they represent different time periods of the entire Church, they show the spiritual condition of members of the one body of Christ, and the judgment and rewards of the saints.You have started with accuracy; although some of your comments are ambiguous. You have side-stepped a clear definition of the seven churches. I will be interested to see how you finish. Please continue.
E.g, there are seven churches of which five are told to repent, and two are told to have crowns: Philadelphia and Smyrna. In revelation 2:22 we read that Thyatira will enter into great tribulation, except they repent of their deeds (Spiritual condition), yet in Revelation 3:10 Philadelphia will be kept from the temptation to come upon all the world (The time of tribulation). The price? Patiently keeping the word, and that judgment of the churches is going on in our walk with Christ even today as Jesus walks among the candlesticks.
I.e., Philadelphia will enjoy the benefit of being caught up alive to meet the Lord in the air as having a crown, while Smyrna having been faithful unto death (Revelation 2:10) and also having a crown will precede them to meet Jesus.
Other spiritual conditions - Revelation 7:9 After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms (Their reward - others had crowns.) in their hands.
Revelation 7:14 And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
Revelation 7:15 Therefore are they before the throne of God, and serve (Servants versus ruling conjointly with Christ) him day and night in his temple: and he that sitteth on the throne shall dwell among them.
I do not know if this is what you're attempting to establish or not; let me know and thanks.
