Seven Churches

Number seven in the Bible is the number of perfection. Therefore, the seven churches here are not only about the churches in Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia, and Laodicea. They refer to all the churches that are established in the time of the Holy Spirit. The letter to the seven churches of the Lord in the book of Revelation is for all the churches that have existed up until now. It is like a signpost for them and a summary of all the words of God in both Old and New Testaments.
