'Seven Churches' in the Bible

John:To the seven churches in Asia.Grace and peace to you from the One who is, who was, and who is coming; from the seven spirits before His throne;

saying, “Write on a scroll what you see and send it to the seven churches: Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia, and Laodicea.”

The secret of the seven stars you saw in My right hand and of the seven gold lampstands is this: The seven stars are the angels of the seven churches, and the seven lampstands are the seven churches.
