What is a medium's purpose?

A medium's role primarily, is to prove life exists after the physical death. Giving evidence of a loved one's existance by character,  description, shared memories, hobbies and being the voice for spirit. 
A medium's role is also to help with healing grief, which can be gained by the evidence and proving that life does, in fact go on. When a loved one passes over, we tend to focus on the passing, an illness or the reasons why someone has passed. In fact virtually everyone that passes has had a lifetime or their lifetime of more than illness or sadness, when a loved one makes contact, they like to recognise their life and maybe the happy times, taking you to happier times to remember them by.
Remembering loved ones at happier times can help with grief immensly. 
A medium is essentially the voice for the spirit side, and as a medium i look at it this way...if i can try my best for the spirit side, to connect to them in the best way for them, to let their loved ones know they live on and are around them, then ive done my bit.
Personal responsibility is a large part of connections, as a medium moves their mind and allows spirits mind to come in, we have a responsibility to them to not distort or change their messages or evidence, this can happen if we, as mediums don't allow that shift to take place but allow our own judgements and opinions to cloud the connection. Every connection will be different and i believe it's a mediums reponsibility to allow a natural shift in energy to take place. Allowing this to take place takes dedication and development with the spiritual and personal growth. 
How can we be the voice of spirit?
We can open as many ways as possible, abilities, recognising from the sensing, seeing and hearing, knowing what is our own thoughts and what is spirits.
