I thought I'd share some of the books I have and use. Feel free to post your own. Keep in mind, though, that they need to be in keeping with the regular rules of this forum. I would post at LEAST the name/author of the book, as well as the publisher. If you can't remember it, that's alright, but make every effort to do so. "Understanding The Times" by David Noebel (Harvest House Publishers) - A comprehensive guide to the major worldviews of our day (Christianity, Marxism/Leninism, and Secular Humanism) from many different viewpoints "Becoming Gods" by Richard Abanes (Harvest House Publishers) - A book that purports (and largely succeeds) to help one understand Mormons and their viewpoints, and interact with them in a spirit of love, without compromising one's own viewpoints "The Faith Once For All" by Jack Cottrell (College Press) - A clear and succinct book (exhaustive too) on Biblical doctrine "Evidence That Demands A Verdict" by Josh McDowell - a VERY exhaustive research book on the validity of Christianity These are just some...I'll be adding to the list.
