When Mary says "yes" at the Annunciation, the divine Word becomes flesh.  The mystery of the Incarnation entails a wondrous exchange of natures.  God takes on our human nature in order to have us share in his divine nature.  God became one of us so that we could become like him.  This lowering of almighty God to share in our human experience and our limitations is very personal.  He did it for you and me, for my good and for yours.  https://comeawaybyyourselves.com
