Yes

Samuel 7:1-5, 8-12, 14, 16; Psalm 89 For ever I will sing the goodness of the Lord; Romans 16:25-27; Luke 1:26-38

"Rejoice, highly favored one, the Lord is with you."

The greeting of the angel to Mary has echoed through the ages.  On the wings of the wind, in the depths of heart of every believer, on the lips of those who proclaim, the greeting summarizes the principle message of Christianity.  "Rejoice!"  The very first word that inaugurates Jesus into history is that of Joy.

Joy descends from the heavens and rises from the earth as God's plan for all is set in motion with Mary's "yes".  Joy is not a feeling but a gift given and a gift received.

In Mary's  "Yes" God is given a dwelling place.  In her "yes" something changes, for the better, for the good, for all, for eternity, for his "Kingdom will have no end".  

God waits on Mary.  He desires her humanity so that he can fill the earth with his divinity.   This kingdom is not built on control or manipulation but on simple freedom to say "yes."

The power of a "yes" should never be taken lightly. 

In Mary we discover  our purpose; we are born to make manifest the glory of God within us. It is not just in some of us, but in all of us.

When we say "yes" something changes for the better, for the good, for all, for eternity, for his kingdom will have no end.  

Let us not delay, let us not keep God waiting.  Let us hasten to greet him, not with a bow or kiss but with a "yes", be it done unto me according to thy word.

Excerpt from St. Bernard:

"Why do you delay, why are you afraid? Believe, give praise, and receive.  Let humility be bold, let modesty be confident.  There is no time for virginal simplicity to forget prudence.  In this matter alone, O prudent Virgin, do not fear to be presumptuous.  Though modest silence is pleasing, dutiful speech is now more necessary.  Open your heart to faith, O Blessed Virgin, your lips to praise, your womb to the Creator.  See, the desired of all nations  is at your door, knocking to enter...Arise, hasten, open.  Arise in faith, hasten in devotion, open in praise and thanksgiving.  Behold the handmaid of the Lord, she says, be it done to me according to your word."
