Fasting?????

The other day I was praying and doing some reading, and I came across Matthew 17:21 "Howbeit this kind goeth not out but by prayer and fasting." That verse hit me right between the eyes. Jesus said in Matthew 6 "when you give","when you pray", and "when you fast". I began to look into fasting because, though I hate to admit it, I had never really fasted. I read a book that was referred to me by a dear friend and found it to be very insightful. The book is Fasting by Jentezen Franklin.I do not know all of his teachings, but those in the book are very insightful. I know fasting is a "scary" word but I encourage everyone(myself included) to take a moment and consider....are we missing out on some "BIG" answers to prayer or a closer relationship with God because of our stomach?
