Anyone can pick up a Bible and read it. The only qualification you need to have to read the Bible is the ability to read. The more challenging piece is believing what you read to access its power. You can have a doctorate in theology and not have the ability to access the Bibles power. Accessing the power of the Bible requires faith. Believe what you read. Place yourself within the pages of Scripture as you read. Don’t resist the emotions it brings out and do not cease reading out loud. You must give confession with your mouth to bring out its power.
For example, you open the Bible and start to read 1 Corinthians 1 out loud and you read and read and read. Right around 2 Corinthians depending on how many demons have control of your life, you will feel light headed, may cough, sweat or hands may begin to shake. Keep reading. The demons within you are being burned by the words of Scripture as they are being read out loud in faith. The weaker ones will flee without any physical feeling the stronger ones that can resist a lot of heat will manifest in your flesh. Keep reading until it smooths out. If you stop prematurely, the demons will regain its strength in you and you will have to begin again. When you feel a lightness, you will know that evil spirit has left your body.
Satan will work to regain control, so you should read like this for a week straight for rapid growth in the spirit and for defeating this evil spirit.
You can be healed through Scripture reading. The power is found in the coupling of faith when you read the KJV Bible out loud. I say, KJV out of personal experience, however other versions of the Scripture may work, but I would certainly say a no go on the NIV.
If nothing happens. Keep reading. Most people think they have faith, when they actually don’t. Reading the Scriptures out loud will build your faith, for some, you may need to read five of Paul’s letters, just to build your faith before activating the power of the Holy Spirit through his Word.
