Brother Randall had been to war and returned a changed man. He fell into various sins including drinking and taking drugs. Pretty soon he was seeing spirits manifest themselves. He found the one prayer, prayed it and vomited. Over the next few weeks he cast more and more demons out of himself. Now he no longer sees spirits, is free from the bondages of sin and praises Jesus.
John 8:36 King James Version (KJV)
36 If the Son therefore shall make you free, ye shall be free indeed.
Use the name of Jesus Christ to set yourself free. It is the name above every name:
Luke 10:19 King James Version (KJV)
19 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.
If you repent from sin, use the name of Jesus to remit sin and expel the spirits from you, they must depart. All you need is faith. If you don’t have faith, read the word of God to build faith:
Romans 10:17 King James Version (KJV)
17 So then faith cometh by hearing, and hearing by the word of God.
