One of the books I am reading on my Kindle, at the present, is Tactics by Gregory Koukl. According to my Kindle, I am only 33% through the book. But, I have to inform you that this is a must read for all you Calvinists whose "Good Cop - Bad Cop" methods of communicating the truth have ended in failure. Greg will transform your thinking - Colombo style. Here are two reviews that should convince you: Apologetics 315 review and the Tim Challies review. Do yourself a big favor and order this book! You'll thank me for it...oh, and just one more thing... you wouldn't happen to know where I left my Kindle would you?
