In the book of Revelation, we find we are reading someone else’s mail. Jesus sent a message through John to specific churches in Asia Minor. But the Spirit has preserved these words to speak to us still today!
His message to Pergamum begins with encouragement for continuing to proclaim the name of Jesus as Lord faithfully in a city hostile to their faith. Yet, they have mixed in idolatrous practices of those around them. Jesus has serious words of warning for that!
