'Seven Churches' in the Bible

John to the seven churches in Asia: spiritual blessing and peace to you from Him who is and was and is to come, and from the seven spirits that are before His throne,

"Write what you see in a book and send it to the seven churches, to Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia, and Laodicea."

The open secret of the seven stars that you have seen in my right hand, and of the seven golden lampstands, is this: The seven stars are the messengers of the seven churches, and the seven lampstands are the seven churches.
