Lyric discussion by shevygirl 

I finally found the meaning behind this song on Toby Mac's official website, and I've just copy/pasted it here for all of you:

What is the meaning behind the song Ill-M-I?

Its basically hip-hop on the art tip. The lyrics of the song are almost whimsical, like word pictures all throughout. The real thought behind the song is its sort of poking at the Pharisees, poking at those who "have it all together." Of course, its basically ILL M I, and you, Illuminati shining through you. Illuminati, people are confused by what that means, but one of the dictionary definitions is 'a person or persons claiming superior spiritual enlightenment.' So, that to me is a Pharisee anyone who claims to be an all-knowing spiritual person. So, it's sort of saying, "Ill am I. I'm all ill down here, and you, Illuminati, shining through."
