Pastor Brian discusses the resilience of the gospel in the face of persecution, using historical examples like the spread of Christianity in China and Eastern Europe during the Cold War. He highlights Acts 8:1-4, where persecution in Jerusalem led to the gospel spreading to Judea and Samaria. Brian encourages faithfulness in sharing the gospel, regardless of circumstances, and notes that even the fiercest opponents of the church, like Saul, can become its greatest missionaries. He concludes by urging the congregation to be consistent in their witness and to trust God for the spread of the gospel.
