R.C. Sproul (1939-2017) was founder of Ligonier Ministries in Orlando, Fla. He was also first minister of preaching and teaching at Saint Andrew's Chapel, first president of Reformation Bible College, and executive editor of Tabletalk magazine. His radio program, Renewing Your Mind, is still broadcast daily on hundreds of radio stations around the world and can also be heard online.

Robert Wolgemuth has been in the book publishing business for over forty years. A former president of Thomas Nelson Publishers, he is the founder of Wolgemuth & Associates, a literary agency representing the work of more than two hundred authors.

The author of over twenty books, Robert is known as a relentless champion for the family, relationship building, and biblical truth. His favorite “audience” is one friend, a corner table in a small café, and a steaming cup of coffee (extra cream but no sugar) between them.

A graduate of Taylor University, from which he received an honorary doctorate in May 2005, Robert has two grown daughters, two sons-in-law, five grandchildren, one grandson-in-law, and a great-grandson named Ezra. He and his wife, Nancy DeMoss Wolgemuth, live in Southwest Michigan.
