MAINTAINING THE CENTRALITY OF EXPOSITORY PREACHING WHILE ADDRESSING ISSUES OF CHURCH HEALTH AT HARVEST EVANGELICAL FREE CHURCH IN BEAVER DAM, WISCONSIN presents a model of leading a local church in the "40 Days of Purpose" by preaching expository sermons followed by a discussion on these sermons during the Adult Bible Fellowship. The "40 Days of Purpose" is a church-based campaign that was created at the Saddleback Community Church in Lake Forest, California, where Rick Warren is the Senior Pastor, and is designed to address five elements of church health: Evangelism, Worship, Fellowship, Discipleship and Service. This project will review Saddleback's understanding of these areas of church health as well as the way they are presented in the "40 Days of Purpose" and present an alternative understanding and presentation, as well the addition of prayer as a key element of church health. As specifically stated in the title, this project contends for the centrality of expository preaching and as such, it presents both the philosophical foundation and the homiletical process of expository preaching.
