*DISCLAIMER: In light of the controversy over Joshua Harris’ book, “I Kissed Dating Goodbye,” I considered removing it from this series. However, during the time that he wrote it, he was seeking the Lord and His will for Christian romance. It is for that reason that I decided to retain his quotes. I do not agree with his recent choices and apostasy from the faith.
