Christian Apologetics and begun a new website by the same name. Groothius is a very good thinker and writer.
See these reviews:
"Douglas Groothuis does Christian apologetics the way it needs to be done, situating apologetics within a Christian worldview and answering the troubling questions that people are actually asking--questions to which they need answers if faith is going to be a live option. His book draws on many years of teaching and writing about apologetics, distilling the most effective arguments in defense of the Christian faith." (William A. Dembski, author of The End of Christianity )
"Christian Apologetics is an outstanding book that I wholeheartedly endorse. It is one of the most thorough, insightful and well-written apologetics books I have read in a long time. Groothuis has the rare ability to write in a way that is understandable to the nonspecialist and yet rigorous enough to challenge the apologetic connoisseur. I wish every Christian would read this book carefully and then pass it on to a skeptic for discussion, interaction and dialogue." (Sean McDowell, author of Apologetics for a New Generation )
"Groothuis is a leading evangelical thinker and Christian Apologetics is a monumental result of decades of study and reflection. Breathtaking in scope, clear in style, this book is now the go-to text in the field. I know of nothing like it, and I enthusiastically recommend it to all who want to learn to give an answer for the hope that is within them." (J. P. Moreland, author of The God Question )
"Christian Apologetics is a full-scale defense of the Christian faith that is accessible, relevant and wise. This book not only reflects the work of a seasoned apologist; it is written with passion and conviction. I heartily recommend it!" (Paul Copan, Palm Beach Atlantic University )
