The Annunciation of Our Lord (click to go to Wikipedia article)

Pour your grace into our hearts, O Lord, that we who have known the incarnation of your Son Jesus Christ, announced by an angel, may by his cross and passion be brought to the glory of his resurrection; who lives and reigns with you, in the unity of the Holy Spirit, one God, now and forever. Amen
(From the Gregorian Sacramentary)

7 Then I said, "Here I am, I have come—
it is written about me in the scroll.
8 I desire to do your will, O my God;
your law is within my heart."
9 I proclaim righteousness in the great assembly;
I do not seal my lips,
as you know, O LORD.
10 I do not hide your righteousness in my heart;
I speak of your faithfulness and salvation.
I do not conceal your love and your truth
from the great assembly.
11 Do not withhold your mercy from me, O LORD;
may your love and your truth always protect me.
Psalm 40 New International Version
