Would she have done it?

On Christmas Eve, our church had a 5:00 worship service featuring the children, youth and Alternative worship band.  I listened as a couple of young people from our church sang a duet of Breath of Heaven.  It's a song written from the standpoint of Mary.

I am waiting in a silent prayer
I am frightened by the load i bear
In a world as cold as stone
Must I walk this path alone
Be with me now
Be with me now

As I listened to them sing, I realized that Mary herself had probably been their age, perhaps the age of the 15 year old youth who sang of the young mother to be.

Breath of Heaven
Hold me together
Be forever near me
Breath of Heaven

Breath of Heaven
Lighten my darkness
Pour over me, your holyness
For your holy Breath of Heaven

Young.  New to the world.  Beloved of God, but not famous, not experienced, not a person with a resume of encounters with the holy leaders of the day.  She didn't have political experience or a degree in theology. She was a young girl, beginning her life.  She was probably afraid, a little lost, and worried what this would all mean in her life.

Do you wonder
As you watch my face
If a wiser one, should of had my place
But I offer-all I am
For the mercy-of your plan
Help me be strong
Help me be
Help me

Would she have done it if she could have seen what it would mean? Would she have said "yes" if she had known it would mean becoming the mother of a young Jesus?  Would she have done it if she had known it would mean knowing he would leave his home and travel across the known world, preaching to sometimes hostile crowds?  Would she have done it if she had understood the nature of Simeon's warning to her?  Would she have done it if she had known it would mean standing at the foot of a cross, watching her son die?

What would it be like to be Mary, young, perhaps 15, listening to the words of an angel?
