OK. . .well. . .I agree with Andrew, we should focus more on Jesus than the devil.
And what I have said, I believe several times is that I do not believe the demons reside "in" a christian. However, if the christian has not gotten rid of the "bondages" they had before they were a christian, or has gone back to "bondages" they had before they were a christian, or has picked up new "bondages" since they have become a christian, they have given the enemy an open door.
Eph 4:27 (NKJ) nor give place to the devil. (Amplified) "Leave no [such] room or foothold for the devil [give no opportunity to him].
Pray tell . . .what foothold might the devil be able to get? On what? Who? Why? Uh, what form might it take if he gets a foothold?
2 Timothy 1:7 For God has not given us the spirit of fear; but of power, and of love, and of a sound mind.
Are we fearful? In any form? Then that's a spirit of fear. And it did not come from God.
1 John 4:18 There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.
Gee, satan is called the tormentor. Fear has torment. The spirit of fear does not come from God. But it can be cast out. Why would that spirit need to be cast out if it's not there? I know many christians who live in fear. Fear for their children, fear for their jobs, fear for their mates, fear for their safety, fear for their health. That is a spirit, and it's not from God.
Romans 8:15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba Father.
Bondage again? Had some of them gotten into bondage again? Certaintly sounds like it.
Proverbs 18:21 Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof.
I hear lot's of christians speaking death over themselves. "I'm stupid, I'm fat, I'm sick, I'm poor, I'm crazy". And we're suprised why we're reaping the words we speak. Are these the devil's footholds?
No my church does not do random checks for demons. They do however, know what's going on in the lives of their leadership. They don't want leadership filled with fear and dread, or caught up in activity that gives footholds to the enemy, laying hands on other people who are even weaker and then passing those spirits on.
We don't have "displays" of casting out demons. When one one manifests, and the person wants deliverance, they are generally taken to another room and it is done privately.
I've seen the difference in far too many christians to know that there is a difference. The difference between bondage and freedom. It can be seen in their faces. It can be seen in their body's. It can be seen in the way they walk in victory over the enemy instead of defeat.
Jesus can do anything. He's the deliverer. We humans are merely the instrument in His Hands.
