There are seven different types of churches listed in the book of The Revelation. They are represented by seven different areas in the major areas in the world at the time of writing. They are Ephesus, Smyrna, Pergamos, Thyatira, Sardis, Philadelphia, and Laodicea. The Holy Spirit thru Paul writes of churches that are in good standing, how that these churches are are living what they teach and doing good works for Christ, spreading the Gospel. There are churches that are trying to walk right and there are churches that are churches in name only, not going after the things of God. The Spirit is giving accolades where they are due, but also reprimanding where it is necessary. The Spirit gives some good, some bad, about each represented church, and then gets to the church at Laodicea! My, oh my!
