God provided other women to assure Mary of God's plan.
Women thrive on community much more than men do. Relationships are very important to us. And our God knows that, because He is the one Who made us that way.
So, in His kindness, He sent not one woman to provide comfort to Mary's heart, but two.
The first was her cousin, Elizabeth.
Luke 1:42-45 "And she spake out with a loud voice, and said, Blessed art thou among women, and blessed is the fruit of thy womb.
And whence is this to me, that the mother of my Lord should come to me?
For, lo, as soon as the voice of thy salutation sounded in mine ears, the babe leaped in my womb for joy.
And blessed is she that believed: for there shall be a performance of those things which were told her from the Lord."
What sweet words of assurance to the fragile, wondering, fearful heart of Mary.
The second woman to give encouragment to Mary was Anna.
Luke 2:38 "And she coming in that instant gave thanks likewise unto the Lord, and
spake of him to all them that looked for redemption in Jerusalem."
Anna's words confirmed again all that the angels had said to Joseph and Mary.
No matter how much faith we have in God's promises to us, it is always a blessing to have a word of encouragment from another woman who understands.
God is faithful to meet the the spiritual and physical needs we have, but He is also so kind to meet the emotional needs of our heart, as well.
