You don't have to be Pentecostal, charismatic, Word Faith or follow "he who shall not be named" on CC to know the ministry of the Spirit! In fact, I was taught that in non-charismatic churches, that no one knew about the Holy Spirit.
When God led me to a Baptist Church, one of the first weeks there, the pastor starting teaching from the Bible of how the Holy Spirit is working in our lives, and how he is in the transformation business. I remember being stunned, because I had been told these sorts of churches had NO Holy Spirit. I mentioned this to the pastor's wife at a prayer meeting, and she laughed, and said, no, Baptists rely on the Holy Spirit and need him as much as anyone.
The Holy Spirit has been with me since the day I was saved. I have heard his voice, seen visions, and had the Spirit illuminate the Word of God. So, maybe on the Day of Pentecost, things had to be done differently, but since that day, when we are saved, it means the Holy Spirit is in our hearts and directing us all the time from the day we are born again. Because how could we be saved, without the Holy Spirit to lead and guide us? It would be like having been "born" and having no mother to care for you.
The Holy Spirit cares for us, like a mother cares for her child! God does not leave us alone, and that is from Day 1. If we don't choose to access the Holy Spirit in our lives, well that is on us!
