Hey, this just happened to me! I moved into a new apartment about 2 months ago and there has been an extremely evil presence in the building I am in. However I just got back from getting groceries and there was a man on my floor who was moving in and I talked to him briefly and as I was talking to him the spirit in the building left! It is nice and peaceful here now! All I did was talk to the man, I am in awe of how God used me! Hallelujah!
