We have 3 or 4 spirits in our house and one is evil. We have a picture of the bathroom wall that has 2 faces in it and one looks like my grandmother. I believe strongly in God so we smudged the house but nothing happened. It has gotten to the point that we can't stay there and the churches in my area kind of laughed at me when I told them the problem. Where do I go for help?

Look up mediums and priests in other locations, mediums are usually connected to people that take this kind of thing seriously.

You believe in God? In what sense and to what degree? Smudging didn't work because smudging has no power behind it. Just like blessing a home, 99% of the time it is not going to work because it's not what is needed.

If a church laughs at anybody for a need they have, you don't want help from that church to begin with. I do, however, doubt that they "laughed" at you.

What exactly is going on that you can no longer stay there?

You do go to the church for help... but finding one that believes you is the first step. I don't know where you went but I might suggest checking out a full gospel or pentecostal church.

I am a Christian, 71 yrs old, and live in a house built back in 1940, which since has been renovated. There are spirits living here, no harm, because we have seen "white flashes" of light, for a second, at different times in one room. There is no explanation, no car lights, etc. Also, a mirror on a bathroom door "flew" off, bending in the middle. Nothing could have made it do that on it's own.
We had a bad spirit and did the following:
Get a small bottle of Virgin Olive Oil. Put some on your finger, and make a cross over an outside door, on the inside, and pray:
By the power of God the Father, Jesus Christ the Son, and the Holy Spirit, I command you to leave our home and never return. Say it at least twice. Then do it over all the doors leading outside. It worked for us. That is all I gave say, it did work for us. Try it again if it didn't do the job the first time.
I do wish you the best, and good luck.
