DEMONS DO NOT LEAVE BY THEIR OWN CHOICE
This is another reason we cast out demons: they do not leave of themselves. As in the situation with the Gadarene in Mark 5, the demons didn’t leave the man — they grew stronger. They cried out when Jesus came, but they did not go out until He cast them out(and with some difficulty).
Some demons may leave during strong spiritual experiences. We call them surface or butterfly demons. We have seen them leave at the point of the new birth or the baptism in the Holy Spirit. The spirit of profanity left me when I was born again. My conversation was cleansed immediately. I now know this was a demon that left me, and I praise God for this.
Mostly, though, believers require much deliverance following new birth and Holy Spirit baptism regardless of how powerful the spiritual experiences.
People say time heals everything. The truth is, time does not heal anything. Jesus heals and casting out demons makes the way for His healing. A demon will stay with you as long as no one tells him to go. Time won’t make him go away. In fact, if you allow him to stay, he will invite his friends into your house (your body) also. If you try to deal with demons by waiting them out or ignoring them, they will get stronger and meaner in your life.
Satan wants to work in secrecy and camouflage. If we have demons in our life and can’t or won’t see them, then the demons have tremendous power in our life. We won’t even realize their influence flowing through us. We may bruise and hurt others or leave a trail of broken relationships. Bitterness may be pouring through us to others, and we will not see it. Until it is confronted as a personality and cast out, it will abide in us. The deeper residential spirits like rejection and rebellion remain more hidden and resist leaving even more.
Some say if you just praise the Lord they will leave; or if you get a prophecy, they’ll leave; if you read the Word or memorize the bible, deliverance will come. Not so! They must be cast out. Jesus did not tell us to sing them out, praise them out, laugh them out, read them out, wait them out or sweat them out. He said, “Cast them out.” “In My name you will cast out demons!”
