What Would Have Happened if Mary had Denied the Presence of God?

What would have happened if 2,000 years ago, Mary the Mother of Jesus had denied the message sent to her? What if her heart was not prepared to receive it? What if, in her troubled state when the angel first visits with her (Luke 1) she disbelieves instead of anticipates?

 
Thankfully, I do not have to be concerned with the “what if’s” for Mary. Her example lays enshrined in history. Her response was faithful and nurtured by anticipation and hope.
 
What about my own hope and anticipation? What if God is today desiring to cause life from himself to take root within my soul? How might my soul be prepared to anticipate, receive and obey in faithfulness? 
 
Yours?
