Christmas isn't just about His birth.

“You can’t separate Bethlehem from Gethsemane or the hasty flight into Egypt from the slow journey to the summit of Calvary. It’s of one piece. It is a single plan. It considers ‘the fall and rising again of many in Israel’ [Luke 2:34], but always in that order. Christmas is joyful not because it is a season or decade or lifetime without pain and privation, but precisely because life does hold those moments for us." ~Jeffrey R. Holland ("Shepherds, Why this Jubilee?" 2000)

I love this quote! Christmas isn't just about His birth, it is also about His life, and His Atonement. They're not separate plans; they are one and the same. Without His birth, there would have been no Atonement, and no example to look up to. They are interwoven events that can never be untangled. He agreed to come to Earth so that He could lead us by His example and so that He could save us with the Atonement because He loves us so much.
