Repetition and "I've read that before"

I was given a book entitled Moments with The Savior, by one of the pastors in my church. Also, i'm currently reading the gospel of Luke in the Bible. Ya know, sometimes it's quite comical how the Lord works. One night i read something in Luke. This, in turn, ended up being something that i had previously read the night before in Moments with The Savior. Even today- stuff like this happens . Case in point- today i got an email from a friend. He was just saying a few ways about how God was speaking to him. Here's part of the email: "When God reveals something he will allow a question to crop up to see if we will yield to his revelation or if we will yield to that which has not happened (ie the question). He doesn't mind the question if explanation is not required for obedience. (Used Zechariah and Mary being visited by the angel. Both asked questions. They both asked "How is this possible?" The difference was in how the question was asked.)" Last night, i had just heard a small devo about the very same thing, Zechariah and Mary. What i ended up hearing in the devo said something like this: (luke 1) There are 2 people presented with something that God is going to do (ie- Zechariah and Mary), both respond in the same way- but the outcome is different. Zechariah asks God how is it possible for his wife to have a son, especially since she was in very old age. Here we see Zechariah doubting God. He doesn't believe that God can do it. For his doubting, God silences him until the baby is born. Then later on, he is given back his voice. On the other hand, Mary's question of "How?" is more along the lines of- I'm a virgin, how are you going to do this? I can't wait to see what Your'e gonna do. The end of this devo had something that really brought a new meaning to this story for me. So again, 2 people, same question, different outcome. For Zechariah, he gets a lesson in what God can do, i.e.- trust. For Mary, she gets to be the vessel that God uses to bring Jesus into the world. As i said before, this type of repetition of things previously read has happened to me a lot recently. I think it's neat when this type of thing happens.
