By AD 90, it was a dark and discouraging time for the church. All the apostles are dead except for John. The first state of the Holy Spirit’s power and work in the church is passed, and she suffers persecution, heresy, and immorality. The Apostle John, exiled to the Isle of Patmos, was given a revelation from the Lord Jesus Christ, and commanded to write letters to seven of the churches in Asia. This introductory lecture provides much important background to these letters, and helps us see how they are still relevant to the church today.
