This is from MacArthur's Book, Preaching: How to Preach Biblically, which he co-wrote with many of the Master's Seminary faculty (www.tms.edu). It is some exhortations that the preacher must remember as he studies the text, prepares the sermon and preaches the sermon:
Preach to honor God's Word
Preach to reach the unconverted
Preach to please God
Preach to equip Christians for the work of the ministry
Preach to lift up the downhearted
Preach to be more effective this time than last
Preach to bring conviction of sin and repentance
Preach to compete with no one but yourself
Preach to refresh the spiritually weary
Preach to exalt the Lord Jesus Christ
May we as preachers take these exhortations to heart and preach biblically and passionately.
