the holy spirit is the one who goes to god with our prayrs, so to speak. and when you pray for the baptism of the holy spirit you pretty much asking for a free tickt as an easy way to talk to god.

not that you need the holy spirit to talk to god, you can do that on your own.

but what the holy spirit does is prays for you thru you(tongues) so that its not so jumbled with the clumsy speach of humans.

the holy spirit is just a faccet of god, one that christians can use to their advantage when they want to pray for other people, themselves or difficult situations we just cant pray about on our own.
