“The angel answered, ‘The Holy Spirit will come upon you, and the power of the Most High will cover you with its shadow. And so the child will be holy and will be called Son of God.”Luke 1:35
God chose the lowliest of all maidens to receive the greatest revelation He could ever give to humanity - the revelation of His Son, the mystery which as Saint Paul describes, He had kept hidden within Himself for many generations, and now had chosen to reveal to humanity. The Virgin believed and gave Her assent to God’s revelation and behold, the Word - the Son of God, became flesh and dwelt amongst us.
