"the pain falls like a curtain ... the questions without answers"

I just watched a video of Raymond singing this song at Congress last year. It was part of the "How Great Is Our God" piece arranged by Dorothy Gates. Raymond and I were in Bible Bowl together, so this scripture reference is quite appropriate:
Oh, the depth of the riches of the wisdom and knowledge of God!
How unsearchable his judgments,
and his paths beyond tracing out!
"Who has known the mind of the Lord?
Or who has been his counselor?"
"Who has ever given to God,
that God should repay him?"
For from him and through him and to him are all things.
To him be the glory forever! Amen.
(Romans 11:33-36)

And the pain falls like a curtain
On the things I once called certain
And I have to say the words I fear the most
I just don't know

And the questions without answers
Come and paralyze the dancer
So I stand here on the stage afraid to move
Afraid to fall, oh, but fall I must
On this truth that my life has been formed from the dust

God is God and I am not
I can only see a part of the picture He's painting
God is God and I am man
So I'll never understand it all
For only God is God

And the sky begins to thunder
And I'm filled with awe and wonder
'Til the only burning question that remains
Is who am I

Can I form a single mountain
Or take the stars in hand and count them
Can I even take a breath without God giving it to me
He is first and last before all that has been
Beyond all that will pass

God is God and I am not
I can only see a part of the picture He's painting
God is God and I am man
So I'll never understand it all
For only God is God

Oh, how great are the riches of His wisdom and knowledge
How unsearchable for to Him and through Him and from Him are all things

So let us worship before the throne
Of the One who is worthy of worship alone

God is God and I am not
I can only see a part of the picture He's painting
God is God and I am man
So I'll never understand it all
For only God is God
