I (Andy) am grateful to J. D. for coauthoring this book with me. His rich wisdom and life experience will serve readers in a way that I can’t. I’m also grateful to my school, Bethlehem College & Seminary, for encouraging and empowering me to research and write in order to spread a passion for the supremacy of God in all things for the joy of all peoples through Jesus Christ. And I thank God for my godly wife, Jenni, who has given me more feedback than anyone else on this book’s content and tone.
I (J. D.) am thankful to Andy for his wisdom, kindness, and patience toward me as we penned this book together, separated by ten thousand miles. What a privilege to work together with him. My leaders at EMU International gave me support and time to complete this project. Dr. Joseph Pipa, President of Greenville Presbyterian Theological Seminary, encouraged me in my early explorations on human conscience. My wife, Kim, is my best editor and critic—and dearest friend.
We would also like to thank Justin Taylor for offering incisive feedback on an earlier version of this book. Several others also reviewed the manuscript, which is all the better for their comments, including Brad Baugham, Brent Belford, Danny Brooks, David Crabb, Sam Crabtree, Chuck Hervas, Scott Jamison, Matt Klem, Dan Miller, Charles Naselli, Tony Reinke, Adrien Segal, Julie Steller, and Kristin Tabb.
