In this lesson Jesus speaks to the churches in Pergamum, Thyatira and Sardis. Two were struggling with false teachers and compromise, but Sardis suffered from none of these things! They had no accusers, no struggles, no persecution, no false apostles! This was not because they were doing everything right! Far from it! Satan didn't have to bother with them because the church in Sardis was fast asleep! Jesus urged them to wake up!
