Getting back to where we left off, Luke 1, 33, next is :
Luke 1, 34 And Mary said to the angel: How shall this be done, because I know not man?
When Gabriel tells her what “shall” happen, he’s referring to the future. A future, which holds for Mary a marriage to Joseph (in fact in ancient Jewish custom the betrothal was considered being married already).
When Mary answers she’s answering in this same context; the future, not her present state, but her future virginity. When she says: “How SHALL this be done, she’s indicating what will happen in the future, not what is happening then nor what happened in the past. When she says “I know not man”, she isn’t referring to her current state of virginity, (that would be out of context to the angels proclamation,) she’s answering about her future. It’s a state of being which will not change in the future, which the angel is referring to.
Let’s use you (justasking) as an example!
Think about it, tonight an angel tells justasking
Tom 1, 26 “You shall fly a helicopter across the Jordan”
Now we know you’re not planning on becoming a helicopter pilot, so you might ask “how shall this be since I’m not a pilot?” You’re not referring to the fact that today you aren’t a pilot; you’re stating the fact that you never plan to be a pilot, not today, not tomorrow, never.
If on the other hand you had always dreamed of being a helicopter pilot, and your training was to begin soon, say within a year, when the angel tells you that you “shall fly a helicopter across the Jordan”, it would make perfect sense. The angel was talking about the future, when you would be a pilot, no need to ask how it shall be, in fact asking would make no sense at all.
Sound logical? If you planned on being a helicopter pilot, and you were soon to start your training, the angels proclamation that you would fly a helicopter across the Jordan makes perfect sense.
If on the other hand you never had any intention of flying helicopters the angels proclamation makes absolutely no sense, you’d have to ask “how”.
