The Prescott conference of today is not the same as the Prescott conference of years ago. A long time ago the preaching at the Prescott conference was directed at the heart. Challenging pastors to be right with God. Challenging pastors to keep their hearts pure and to keep their hearts steadfast following Christ, who had called them into the ministry. This is why pastor Mitchell called the Prescott conference a people's conference. Everyone could benefit from heart directed preaching.
Something began to change in conference and today the Prescott conference is about how to be a better pastor and how to keep the main thing of evangelism as the main thing. We do not let a man whose heart is not right with God pastor a church, but we do not apply the Bible to men's hearts so that they can be changed. We substituted evangelism, discipleship, and church planting instead of keeping your heart right with God. These are not the same thing.
I think we need to go back to preaching practical righteousness instead of preaching the Vision. Only a few benefit from vision preaching while all benefit from heart preaching. Ask God to show you how to preach to people's hearts and then do it.
