God the Father imparted to Mary his fruitfulness as far as a mere creature was capable of receiving it, to enable her to bring forth his Son and all the members of his mystical body.
God the Son came down into her virginal womb as a new Adam into his earthly paradise, to take his delight there and produce hidden wonders of grace.
God-made-man found freedom in imprisoning himself in her womb. He displayed power in allowing himself to be borne by this young maiden. He found his glory and that of his Father in hiding his splendors from all creatures here below and revealing them only to Mary.
