Why do Christians need to be baptized with the Holy Spirit?

The term "baptised with the Holy Spirit" has several meanings within Christianity. Which meaning and term are you referring to in this usage.

I am aware of the terms "Christian water baptism" and it has been said by some churches that we still need to be baptized of the Holy Spirit. So, I was wondering what the group believes about these two views.

Some churches teach that at baptism you are filled with the holy spirit while others have this at a confirmation service in their church, while still others have it as a separate event that involves a sign of the gifts of the holy spirit. In the end all of them basically believe in the holy spirit living in them, it is just a difference between how the spirit arrives in the person.
And I guess I have to ask what your position is, since you word your question as "christians this or that" but in your profile you appear to be a minister and have a minister.com email address.
