Well, I am sorry to hear that! But we can not prove the manifestation of the Holy Spirit is not real just because there is false out there.
The "manifestation" always "the manifestation!," and you can't even define it or you wouldn't keep using it that way.
Here it is again defined in another translation:
(CEV) The Spirit has given each of us a special way of serving others.
The manifestation of the Spirit is simply the special ability that each of has of serving others. That is all it is. No one on this board would disagree with that except you who attaches some esoteric existential meaning to this word.
First the "Manifestation of the Spirit" has nothing to do with "the indwelling" of the Spirit which comes once and only once in a person's lifetime, and that is when they are saved. That is what happened to those 3,000 believers, who, BTW, never spoke in tongues. The 120 did, but not the 3,000.
We all have different ways of serving the Lord, but not in the same way as they did in the first century. Those ways are past. God works in different ways at different times in history. He gave some signs to the Apostles that he doesn't give now. He gave some signs for the Jews, some because revelation was still being written, some to authenticate the apostles, and their message. These were called "sign gifts." They, especially, have ceased.
There are two interpretations among Baptists about the gifts.
Some divide the spiritual gifts into two groups.
Many believe that just the sign gifts have cease: those that would fall into the categories I have mentioned to you: miraculous, revelatory, apostolic, etc.
And the other more general still exist: the gifts of: helps, faith, administration, etc.
I believe that all the gifts, being somehow supernatural in nature and therefore different than today have ceased, but I would not strongly disagree with the person that takes the first position that only the "sign gifts" have ceased.
Either way they are not for today as 2Cor.12:12; Heb.2:3,4 more than adequately point out along with 1Cor.14:21 and 1Cor.13:8ff.
That does not mean that God doesn't enable believer to serve him with special gifts. I have seen men, who previously were not able to speak in front of any people (fear of public speaking), after being saved and called of God into the ministry become mighty preachers for the Lord. What enabled them to preach in front of hundreds of people, whereas a few years before that time they could not speak in front of a dozen? Only the Holy Spirit can do such a work of grace!
"God gives gifts unto men," but not the same gifts mentioned in 1Cor.12.
Indwelling is far different than manifestation.
