Two Reactions

I'm following a chronological reading plan for my daily bible reading right now. A few days ago, I read Luke 1, which has Mary and Zechariah both finding out that they're going to be parents. Now, you may be thinking, I thought it was Mary and Joseph, and you'd be right, but Zechariah is the father of John the Baptist, and in Luke 1, he finds out that his wife is going to have a baby boy. For Zechariah, this was pretty unbelievable news. Luke tells us that Zechariah wife Elizabeth was barren, and too old to have children besides. Luke goes on to say that Zechariah is a pretty old guy himself, and that, relying solely on nature, no baby is going to show up. Mary, on the other hand, is of child-bearing age, but also a virgin, which means that she's not going to get pregnant naturally either.

An angel appears to both of them, telling them almost the same news, that they're each going to have a baby boy. The thing that struck me was the difference between their reactions.

"Zechariah asked the Angel, 'How can I be sure of this? I am an old man, and my wife is well along in years.'" Luke 1:18

"'How will this be,' Mary asked the Angel, 'Since I am a virgin?'" Luke 1:34

The difference between these responses was what struck me. Boiled down, their responses are, "How can I be sure I can trust you?" and "How will it work?" While Zechariah's response comes with some element of doubt, Mary's response implies that she believes it'll happen, and is confused about the mechanics.

Personally, I find that I want to be like Mary, I want to just start off by trusting God, and by knowing that God has it all in hand. I want my questions to God to be around, what should I be doing? How will it work? but I find that my questions are more toward the, "How can I be sure I can trust you?" God deserves better from me.
