I have yet to meet a writer who has not experienced self-doubt. If you are plagued by this demon, cast it out in the Name of Jesus. 

Yes, I said, “Cast it out!” As a born-again follower of Christ, you have the power and the authority to cast out devils. So use that power and that authority. 

The demon of self-doubt wants to keep you from writing for God. Resist that demon with the Word of God and watch it flee from you. 

Remember that greater is He Who is in you than he who is in the world (I John 4:4).
