I am currently fasting (Matthew 17:21) to overcome a spirit of adultery - I have not committed it, but I have been getting unwanted advances from women I do not even know (I go down the street to a Taco Bell, and I get bothered by some lady working there). While I was fasting one evening, I saw a spirit that looked like a woman in a blue dress - this spirit has been following me everywhere, and I assume it is the reason for the problems. I told the spirit to leave, but it is stubborn. I felt the Lord tell me to keep fasting and to watch my thought life more - even innocent thoughts can cause problems.
I am under a bit of pressure right now from work/job, and this is making the situation all the more problematic. I don't know if anyone else has ever seen this kind of spirit, but this demon is a light blue color and looks like a woman. I am doing ok right now, but I just wanted some encouragement and any advice you folks might have.
