1Co 12:4 There are different kinds of spiritual gifts, but they all come from the same Spirit.
Whatever gift (charisma) we are talking about, they all have the same source. The Holy Spirit. The word Spirit is pneuma which means a current of air. You will note that on the day of Pentecost it says in Acts 2:2 there was a sound from heaven (Greek echoes, a loud or confused noise) as of a rushing mighty wind (please note there was no wind, only the sound of it,) and it filled all the house(Oikos) where they were sitting.
We do ourselves a disservice if we are not prepared for the sound of a rushing mighty wind if the gifts are in operation.
If, by any chance, the room is filled with the sound of a rushing mighty wind, do not be surprised if you end up on your backside as when the Holy Spirit is present, IT IS POWERFUL. Do not despise this fact. I have been involved in meetings where whether I wanted people to fall under the power of Spirit or not I had no choice because it happened without my intervention or assistance.
Instead of worrying about what is right and wrong, we should focus more on what is happening by the Spirit and what he is telling us to do. Do as you're told and anything can happen.
