I have been confused about the Holy Spirit quite awhile. A few months ago I believed that the Holy Spirit comes and goes, but then a few people told me you receive the Holy Spirit when you become a Christian (accept Christ into your life.) I go to a Pentecostal church and I don't really have a choice (I'm 17) otherwise my mother doesn't really give me the choice of going to another church because she doesn't trust that i'll be out there searching for God. I still try to go along with her church but the whole speaking in tongues and Holy Spirit confuses me. I hear about people receiving the Holy Spirit and I feel so confused because in my mind I say "but I thought you receive the Holy Spirit when you become a Christian." I was already explained about tongues, but I don't know how the Holy Spirit has anything to do with speaking tongues at all or if they have any connection! The church confuses me, and it has many surprises that scare me. I wanted to know because the church sometimes makes me feel confused because the pastor doesn't speak much about the bible but more emphasis on the Holy Spirit and what God has told her for the rest of the people in Church.
So, what is the Holy Spirit exactly? what is it to receive the presence of the Holy Spirit? What does the Holy Spirit do?
