Caedmon's Call says it all.

Sometimes I can't figure out how to describe how I feel. I can't figure out what to say (or write on this blog) and so I say nothing. Then I hear a song that says what I think. It says what I'm feeling.

Sometimes I believe all the lies
So I can do the things I should despise
And every day I am swayed
By whatever is on my mind

I hear it all depends on my faith
So I'm feeling precarious
The only problem I have with these mysteries
Is they're so mysterious

And like a consumer I've been thinking
If I could just get a bit more
More than my 15 minutes of faith,
Then I'd be secure

(Chorus)
My faith is like shifting sand
Changed by every wave
My faith is like shifting sand
So I stand on grace

I've begged you for some proof
For my Thomas eyes to see
A slithering staff, a leprous hand
And lions resting lazily

A glimpse of your back-side glory
And this soaked altar going ablaze
But you know I've seen so much
I explained it away

Chorus

Waters rose as my doubts reigned
My sand-castle faith, it slipped away
Found myself standing on your grace
It'd been there all the time
