Thread: Hidden Art

This is my second attempt at lyrics, so I'm still struggling with the art in general.

Background: The leader of the college ministry I attend said that he's wanting to do more original songs this upcoming semester, and so he encouraged us to try to write songs if we felt led.

The concept of this song is taking the idea of sanctification (the process of the Lord removing our imperfections and making us more like him) and applying it to a sculptor making a sculpture out of what started off as a giant boulder/slab of rock.

Is the word picture weak, about right, too strong, or unclear?

I am curious as to your opinions of whether a rhyme scheme is necessary. This song doesn't employ one except for in the chorus. Also, are all the lines supposed to have the same number of syllables, and how exactly does meter work into lyrics?

I'm not terribly happy with these lyrics yet, so please, any advice would be greatly appreciated.

Hidden Art (Working Title)

I’m a solid mass of rock
I’m unfinished and I’m rough
Big, stubborn, and bulky
I am nothing but a blight

But You saw something deeper
Somehow, You saw something more
You saw something worth saving
Not just my exterior

It’s going to take some work
There’s going to be some pain
You chisel away defects
Revealing an unseen art

No, I’m not a masterpiece
But You continue working
And slowly I get closer
To the beauty underneath

Chorus
You knew my every weakness
And You knew my every flaw
You looked beyond the roughness
Seeing me at my most raw.
Removing all the dullness
And replacing it with awe
A beauty most would dismiss
was beauty only You saw.

I know the word definition of meter, but I really haven't ever learned how to use it properly. Does anyone have advice? links?
