Mary The Maidservant. 

Not many people have an angel tell them their future. Let alone say that they are to be miraculously pregnant. Even saying the Holy Spirit is involved, few in those days had even heard of Him. 

But Mary took it all in her stride, mothers do that. 

I am Your maidservant. 

This is why Mary found favour with God - He knew her response.

(Luke 1:30-38)
