Sounds almost theological to me, which struck me as interesting as it's not something Ace Enders tends to write about. I think he's reassuring the listener that fear is nothing to be fearful of.

The lines:

Now walk through the door, the same one you came in, so we can go back, to how things used to be, And just walk through the door, the same one, you came in, so we can go back, to how things used to be

I think he's saying that in birth and death, we're visiting the same place.

However,

He holds the key, to your smile and he, won't let you, to close to half of what you want, But not I, think of it, we've known him our whole life, and we still don't know who, or what he wants

He's pretty much talking about fear as if it "he" was physical.
