Joyce and I decided we wanted some birds in our back yard, and our neighbors told us about purple Martins. We asked, "How do you catch the Martins?" They said, "You just have to create the right atmosphere, and they will come." So we got the specific kind of bird house, put it up on a long pole; and now we have purple Martins. They nest in our yard because we have put out a welcome mat for them.
Many Christians have unwittingly given a place to the devil by creating an atmosphere where he feels at home. It's as if they've put out a welcome mat for Satan.
But be encouraged; you are not a helpless victim. Satan can never take any ground that you do not give him. And there is a way you can remove Satan if you have given him a place. You can take back lost ground.
The Removal of Sin
Remember Satan wants an atmosphere in which he can live comfortably, and that atmosphere is sin. Look at Ephesians 4:25, and begin reading about some of the sins Paul mentions specifically that make a welcome place for the devil in your life.
The Renewal of the Spirit
After the removal of sin, there must be a renewal of your spirit. Verse twenty-four instructs us to, "... put on the new man, which after God is created in righteousness and true holiness."
While Satan feels at home in sin, the Holy Spirit does not. The Holy Spirit is just that — the Holy Spirit of God. Therefore, holiness makes him feel at home, but unholiness grieves Him (see verse thirty).
Put away those things that have caused the Holy Spirit to be grieved, so He may feel at home in your heart.
The Resistance of Satan
Even though you've removed sin and invited the Holy Spirit to come and fill you, Satan has to be evicted. He's not going to just walk out. James 4:7 instructs us, "Submit yourselves therefore to God. Resist the devil, and he will flee from you."
Now, if you haven't submitted to God, don't try to resist the devil. You haven't got what it takes. You have to resist him in the name of Jesus. But when your heart is clean and Christ is enthroned through the Holy Spirit, you can say, "I belong to Jesus Christ. My sin is under His blood. There is no unconfessed, unrepented-of sin in my life. I have enthroned Christ, and I am filled with His Spirit. You are trespassing on my Father's property. In the name of Jesus and with the authority of the Word of God; I command you to leave."
Jesus gives us power over our enemy (Luke 10:19). But you have to learn how to use it. It's time God's people took back lost ground!
