How demons can affect a believer? When casting out demons we must have an idea on the ways that demons can affect a believer as well as a non-believer. The following are ways the demons can affect a believer:
Thought life: A believer must learn how to protect the mind. The enemy’s number one area of attack is the the mind. The demons will put negative or even perverse thoughts on your mind to make you believe that they are your thoughts. Do not accept these thoughts. Learn to Bind the thoughts in the name of Jesus. The Word of God in Matthew 18:18 says whatsoever you shall bind on earth shall be bound in heaven and whatsoever you shall loose on earth shall be loosed in heaven. This technique must be practiced to become perfected. The demons know who has authority and who does not. You must be built up on your most holy faith by devouring the Word of God on a daily basis.
The tongue (words that we speak). In the book of James the Word of God says that the tongue is a fire a world of iniquity and cannot be tamed by man. The words that we speak are so very important. Jesus even said that we shall give account for every idle word that we speak. The words that we speak can and will attract demons to us. For instance, if we constantly are saying “I feel sick or I have a headache”, the demons will pick up on those words and come to enforce them on us. The realization to the believer is that words are a medium of prayer and victory, however, they can also be a medium of defeat to the believer. The believer must learn to put a guard on the mouth concerning the words that are spoken.
