More specifically, I think this song is about amplifying and glorifying God through music. Reese is exploring how, through all the details of performing a show (verses 1 & 2), his main purpose in his music is to amplify JC. In the prechorus, chorus and bridge Reese makes it clear that that is what he sees as the purpose of his existence, so naturally it is that message, not the music itself, that he wants to amplify.
