All revelation is summons or sending.
Martin Buber
The pilgrim resolves that the one who returns will not be the same person as the one who set out.
We are all meant to be mothers of God. What good is it to me if this eternal birth of the divine Son takes place unceasingly but does not take place within myself? And, what good is it to me if Mary is full of grace if I am not also full of grace? What good is it to me for the Creator to give birth to his Son if I do not also give birth to him in my time and my culture? Then, then, is the fullness of time: When the Son of God is begotten in us.
"According to ancient Christian writers, God waits for Mary's yes; creation waits; Adam and Eve wait, the dead in the underworld wait; the angels wait; and so do we. With Mary's yes, hope is enlivened and history is changed. There is an unimaginable future for all people, a future that comes from God. All nations assemble in justice, compassion and gratitude. Salvation is created among us, and the fate of history is altered by a godly presence. This salvation resides in the hearts of those who believe in the gift and who stay awake eagerly to know it is coming. With David we await it, with the nations we long for it, and with Mary we behold it."
