Dear Kim. Having come from a non-Christian family where my mother enjoyed having seances with us, ouija boards, etc and such,...and finding out after we accepted Christ, that she had been possessed, I am forever grateful for the care of our new pastor at that time, so many years ago. He had never dealt with those things before, but went totally by the Scriptures, and his incredible example of faith and prayer. We were brand new in the world of Christianity and the occult was real ....as was the possession. 
My mother later recounted having to physically leave the kitchen to keep from stabbing me with a knife...she held that feeling most of my life until I was a teenager. And the Lord delivered her and our family at that time. The BB banner really is true--The Truth shall set you free. Many don't realize how many are desparate for that freedom and don't even know it. 
The point is, most people do not understand that these things can heavily impact families. My grandmother was into the occult and used to take my mother to various activities. These things are foreign to most Christians, especially those brought up in a Christian environment. The Scriptures talk about it. Christ dealt with it, as did the apostles. It was a fact then and is a fact now. It doesn't make it easier. It just is part of what is. 
1 Cor 15:57  But thanks be to God, which giveth us the victory through our Lord Jesus Christ.
58  Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.
1 John 5:4  For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
5  Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
6  This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.
Romans 8:37  Nay, in all these things we are more than conquerors through him that loved us.
38  For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
39  Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
