The Left Behind series are great. Loved the books, read 10 of them and lost interest on number 10. Reading them will definetly make you think about where you are in life. I have started reading more biblical pieces since these books. Herbert W. Armstrong I have found is the best.

 These are a great read and will definetly get you to thinking about where you are in life and where you are going to be. For the nonbiblical person these are a good beginning, I urge to find the truth for yourself in the gods on words "The Bible".
