One of the main reasons Paul wrote his letter to the Corinthians was their apparent lack of concern for sexual immorality within the church. Paul emphasizes the importance of addressing this issue and administering church discipline out of love for Jesus and love for the brother or sister who is engaging in sin. This sermon provides an opportunity to explore the importance of holiness and the necessity of church discipline. It also offers a counterpoint both to those who argue that "Christians shouldn't judge others" and to those who tend to overlook the sins of those within the church while judging the sins of those outside of it.
