God Does This Kind of Thing...

 Luke 1:34 And Mary said to the angel, “How will this be, since I am a virgin?”35 And the angel answered her, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy—the Son of God. 36 And behold, your relative Elizabeth in her old age has also conceived a son, and this is the sixth month with her who was called barren. 37 For nothing will be impossible with God.”

God thinks outside the box because He is outside the box.  He is creative.  Not only can we look around us to see the wonders of His creative hand; we can look at human and biblical history to be amazed.  When we ask ourselves (and God): "How could this happen?", He is able to direct us to points in the past, and the present, which remind us He can and He does.  Mary was amazed but not so amazed she could not nor would not believe. Her faith led to action. She submitted to God's will, and she went on to visit Elizabeth. The incarnation is amazing in all its details, but not impossible. God can, He wants to, and He does.
