Mine?

For what it's worth,
A thousand words
Can't even begin to describe
How I feel about you.
A light is shining brightly now.
That means I'm no longer in the dark.
You have become my light.
My knight in shining armor.
For what it's worth,
Those three little words
Are exactly what I feel for you.
So I ask of you,
Be my light?
Be my knight in shining armor?
Be mine for all eternity?
