"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." Apostle John was exiled to Patmos Island and received many revelations about the last days which includes the messages for the seven churches. It gives a great lesson to the churches and believers of today also, and helps us understand the most ideal type of church that can be praised by God. It's because the churches represent all the churches of this world: the church of Ephesus, rebuked for forsaking their first love; the church of Smyrna, overcoming trials of faith; the church of Pergamum, lukewarm and stained with heretical theory; the church of Thyatira, compromising with the world and eating things sacrificed to idols; the church of Sardis, a small church with a name that they were alive but dead; the church of Philadelphia, receiving only commendation for acting with faith; and the church of Laodicea, a big church that was neither hot nor cold.
