Ephesians 6:12 states that we are in a spiritual battle. You have lost the battle already if you do not even believe that the enemy camp exist in reality. Denial is not victory for your side it is defeat.
I believe in a literal Devil and the spirit world of his minions:
1) Jesus believed in the existence of a literal Satan.
2) The parables that Jesus told were stories that do not need to be literally true. The temptation of Jesus in the wilderness is not a parable but told as a literal historic event.
3) Satan is dealt with in scripture with such specificity that we must take note of the intention of the text with his existence. Why waste our time on a fictional symbolic character when we have such detail and he has such a key role in the story of God?
Ok that is my top 3. I am not to saying that there is a demon under every rock but I am encouraging Christians to wake up to the spiritual realities of the world around them. The world you live in is about more than Starbucks, big box stores and your weekly dose of American Idol, The Office and 24! Reread Ephesians 6:12... just for the fun of it!
For the sake of space I will leave you with the main text that deal with "the old pitch fork and horned man". Enjoy your study of the Great Dragon!
Be diligent in your study. Be prayerful in your study.
The more you know the stronger your faith will be in the Word of God.
