I came across this video explaining the story behind the writing of the song ‘Healer’ by Hillsong. Just a warning, this will mess you up
You can see the actual performance of the song here.
Update: It turns out this disease was fabricated. You can read the whole story here.

Excellent! Thank you so much for posting. We have just received the new DVD from Hillsong and thought there must have been a story behind this guy, and yes an excellent song as well.
