? about the lyrics of this song

The song is named Jesus in Disguise by Brandon Heath (lyrics at bottom)

I've been listening to this song for years, at first it made me cry. But that's not the point. I want to know what you guy's interpretations of this song are.
Especially the part that says "Jesus in Disguise"
But also the other parts


To me I start seeing it as Jesus is as disguised as every person we may meet. Every person can be a teacher to yourself.

What you all think?

Here's some lyrics:
"Ever get something in your head?
It's nothing you heard
Or something you read"...
