Many Christians have never experienced the reality of evil spirits because they have never entered a situation where the Holy Spirit was invited to move in power to make real the presence of Jesus Christ.
When the Lord Jesus is present by the power of the Holy Spirit, He may come with such intensity and presence that evil spirits hiding within people are forced out into the open to indicate their presence.
At that point, the Holy Spirit empowers Christians in the authority of Jesus to cast the evil spirits out.

Jesus dealt with demons
Luke 7:21 “At that very time Jesus cured many people of diseases, sicknesses, and evil spirits, and granted sight to many who were blind.”
In the New Testament there are accounts of Jesus Christ ministering among crowds of people, preaching, teaching, healing the sick and casting out demons.
“Now when the sun was setting all those who had any that were sick with various diseases brought them to him; and he laid his hands on every one of them and healed them. And demons also came out of many, crying, `You are the Son of God!’ But he rebuked them, and would not allow them to speak, because they knew that he was the Christ.” (Luke 4:40-41)
What may be surprising to many is how seriously Martin Luther, John Calvin and other reformers took spiritual warfare.
John Calvin makes the following astonishing statements warning us of the spiritual war in which we are called as Christians.
“All that Scripture teaches concerning devils aims at arousing us to take precaution against their stratagems and contrivances, and also to make us equip ourselves with those weapons which are strong and powerful enough to vanquish these most powerful foes.” 
[1 Institutes of Christian Religion (Philadelphia, 1973) Book I, 14, 13, pp. 172-173.]
A Corporate Experience Of Jesus Casting The Demonic Out Of People
In this video, I share a true encounter about how the Holy Spirit set people free from evil spirits during a Dunamis Project on Spiritual Warfare at a Chinese church in Flushing New York.
At this Dunamis event, we experienced Jesus Christ working in power, authority and love. He set people free from demonic oppression.
After a full day of teaching on how to discern the presence of evil spirits and preparing the teams to cooperate with Jesus in casting them out, we moved into the evening meeting. A number of new people showed up that night seeking ministry.
In prayer, a sudden flash of revelation came to me that Jesus through the Holy Spirit was going to do the same kind of deliverance among our group, much to the same degree in terms of the numbers of people He wanted to set free.
Actually this seemed a little over the edge! But I shared it with the teaching team for discernment. They weren’t sure, but they agreed we should go forward and see what the Holy Spirit would do. We did. And the Holy Spirit came in power.
As we look back on what happened, we believe the Lord had great compassion on the many gathered there with so many spiritual needs.
We praise Jesus that He acted on such a grand scale—we couldn’t have imagined how our ministry teams could have attended to all those who needed personal prayer ministry to be set free.
Jesus had equipped us to be the means of setting others free.
