Union with God may also be expressed in terms of inward birth. The soul corresponds to the Blessed Virgin. It recalls the mystery of the incarnation. And the incarnation is spiritually extended to holy souls who are thereby preparing for Christ’s return. All the mysteries of the Gospel are not only performed in the liturgy but take possession of us in the spiritual life. The Word is continually being born in the stable of our heart.
«Ιn order that the dispositions of the Gospel and the things of the Holy Spirit may develop in us, their author has to be born in us.» Gregory οf Nyssa Against Eunomius (PG 45,585)
«God always wishes to become incarnate in those who are worthy of it.» Μaximus the Cοnfessor Questions to Thalassius, 22 (PG 90,321)
