Wiersbe provides clergy a resource on preaching biographical sermons. He includes tips for the sermon as well as "notes" he made throughout the years on various Biblical persons. This section is not highly readable. It seems more like "note cards" with sound bites taken from other sermons, commentaries, and Christian books with information pertaining to the subject or some aspect of the subject's life. Perhaps my favorite takeaway from the entire book is a quote by C. H. Spurgeon on Paul pertaining to 2 Timothy 4:13:

He is inspired, and yet he wants books! He has been preaching for at least thirty years, and yet he wants books! He has seen the Lord, and yet he wants books! He had a wider experience than most men, and yet he wants books! He has been caught up into the third heaven, and had heard things which it was unlawful for a man to utter, yet he wants books! He had written the major part of the New Testament, and yet he wants books! The apostles says to Timothy and so he says to every preacher, "Give thyself unto reading."

I actually looked up the passage in Spurgeon's sermon, and I think Wiersbe should have added a couple more lines to his note card for the next sentences in that selection state: The man who never reads will never be read; he who never quotes will never be quoted. He who will not use the thoughts of other men's brains, proves that he has no brains of his own. ( )
