Leadership Journal provides an interesting interview with several well known pastors and leaders in "Biblical Authority & Today's Preacher." David Anderson, John M. Buchanan, R. Albert Mohler, Jr., Tullian Tchividjian, and Rick Warren are interviewed (bios are in the article) along with earlier comments from Billy Graham.
You can read the article here. It summarizes points of agreement as:
A calling to preach. All the pastors interviewed for this article believe they have been divinely called to a ministry of proclaiming God's Word, and their calls have been affirmed by their faith communities.Passion for God's word. All are clearly passionate about communicating the Word of God.
Pastors' hearts. Each person evidences a deep love for the people they serve and lead. All are committed to ministering in the context of community, not as lone rangers relying on their considerable communication gifts.
A sense of awe and responsibility for the pulpit. Just as athletes talk about "respecting the game," these leaders all have a high view of the preaching office, which is a great burden and responsibility.
