All love tends to become like that which it loves. God loved man; therefore He became man. For nine months her own body was the natural Eucharist, in which God shared communion with human life, thus preparing for that greater Eucharist when human life would commune with the Divine. Mary’s joy was to form Christ in her own body; her joy now is to form Christ in our souls. In this Mystery, we pray to become pregnant with the Christ spirit, giving Him new lips with which He may speak of His Father, new hands with which He may feed the poor, and a new heart with which He may love everyone, even enemies.
--Archbishop Fulton Sheen, The Fifteen Mysteries of the Rosary
