In Christian tradition, the Annunciation refers to that event where the angel Gabriel announced to Mary that she would miraculously conceive and give birth to the long-expected Messiah. Now Christmas Day typically receives greater attention, but one could make a case for Annunciation Day being a more important holiday. Since the Incarnation of the Son of God actually took place then – nine months prior! So there is much we can learn from this glorious event.
