Luk 1:34 And Mary said to the angel, “How will this be, since I am not having sexual relations with a husband?”
Luk 1:35 And the angel answered — he said this to her, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you. This is also why the one to be born will be called holy, the Son of God.
Luk 1:36 And notice, your relative Elizabeth–she also has conceived a son in her old age, and this is the sixth month for her who had been called barren.
Luk 1:37 Because every word predicted will not be impossible with God”
Luk 1:38 So Mary said, “Notice, the Lord’s female bondservant! May it happen to me according to your predicted word.” And the angel went away from her.
Mary had not asked the same question that Zechariah had. She asked how what was predicted was going to happen, since she was not in a physical relationship with Joseph yet. The angel’s answer: the Holy Spirit will do this. Mary (in essence) said “sign me up.” If God is in this, I will sell myself to him to do his will. That is what faith sounds like.
LORD, come upon us, overshadow us with your power, and accomplish your will through us!
