Continuing our study of Christ’s letters to the seven churches, we will turn our attention in this lecture to the three churches in the center of this literary section. These three congregations—located in the cities of Pergamum, Thyatira, and Sardis—are all commended for their acts of faithfulness to Christ yet still struggle with real problems. To believers of all ages who wrestle with the tension between their desire to live for Christ and their sin, these letters offer both deep encouragement and a call to renewed obedience.
