Expectations

"Now in the sixth month the angel Gabriel was sent from God to a city in Galilee called Nazareth, to a virgin engaged to a man whose name was Joseph, of the descendants of David; and the virgin's name was Mary.
And coming in, he said to her, "Greetings, favored one! The Lord is with you."
But she was very perplexed at this statement, and kept pondering what kind of salutation this was. The angel said to her, "Do not be afraid, Mary; for you have found favor with God.
And behold, you will conceive in your womb and bear a son, and you shall name Him Jesus.
He will be great and will be called the Son of the Most High; and the Lord God will give Him the throne of His father David; and He will reign over the house of Jacob forever, and His kingdom will have no end." Mary said to the angel, "How can this be, since I am a virgin?"
The angel answered and said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; and for that reason the holy Child shall be called the Son of God. And behold, even your relative Elizabeth has also conceived a son in her old age; and she who was called barren is now in her sixth month. For nothing will be impossible with God." And Mary said, "Behold, the bondslave of the Lord; may it be done to me according to your word." And the angel departed from her.

"Now at this time Mary arose and went in a hurry to the hill country, to a city of Judah, and entered the house of Zacharias and greeted Elizabeth.
When Elizabeth heard Mary's greeting, the baby leaped in her womb; and Elizabeth was filled with the Holy Spirit, and she cried out with a loud voice and said,
"Blessed are you among women, and blessed is the fruit of your womb!
And how has it happened to me, that the mother of my Lord would come to me? For behold, when the sound of your greeting reached my ears, the baby leaped in my womb for joy. And blessed is she who believed that there would be a fulfillment of what had been spoken to her by the Lord."

And Mary said:
"My soul exalts the Lord, And my spirit has rejoiced in God my Savior.
"For He has had regard for the humble state of His bondslave;
For behold, from this time on all generations will count me blessed.
"For the Mighty One has done great things for me;
And holy is His name.
"HIS MERCY IS UPON GENERATION AFTER GENERATION
TOWARD THOSE WHO FEAR HIM.
"He has done mighty deeds with His arm;
He has scattered those who were proud in the thoughts of their heart.
"He has brought down rulers from their thrones,
And has exalted those who were humble.
"HE HAS FILLED THE HUNGRY WITH GOOD THINGS;
And sent away the rich empty-handed.
"He has given help to Israel His servant,
In remembrance of His mercy,
As He spoke to our fathers,
To Abraham and his descendants forever."
Luke 1:26-55

In these passages, the angel Gabriel comes to Mary, unveiling what is about to happen, and Mary accepts the angels's words without a hint of doubt or question (unlike Zechariah). But why did she go to see Elizabeth, was it just for a visit or was she so full of expectation that she just had to get there as quick as possible? Elizabeth and Mary were cousins, but Elizabeth was quite a bit older, they probably hardly knew each other, but Mary was compelled to travel to Elizabeth as fast as she could get there, wondering, hoping, but nonetheless, believing.
The Holy Spirit, revealed the miracle to the pregnant Elizabeth, and to the unborn John(!), v.45 records the confirmation:
And blessed is she who believed that there would be a fulfillment of what had been spoken to her by the Lord."
Believing- the act of actual belief, the realization, fruition of prophetic utterance, and God's promises. Would Jesus have been carried in the womb of an unbelieving or doubting mother? Absolutely not. Mary had been preselected to carry the Savior of mankind because of her faith, her pure and believing heart, not primarily because of lineage, etc..
The eyes of the Lord have never ceased looking for those who are pure in heart, those who believe His promises, who are pregnant with faith, hope, and love, bearing that same spirit that dwelt in an expectant Mary.
Today beloved, let us be found believing and expectant...we have good reason to!
