From The Treasury for Annunciation

Most of the holy fathers and patriarchs and prophets desired to see Him with their own eyes, but did not. Some of them by visions beheld Him in type, and darkly; others, again, were privileged to hear the divine voice through the medium of the cloud and were favored with the vision of holy angels. But only to Mary the pure virgin did the archangel Gabriel manifest himself in brilliant light, bringing her the glad address, “Hail, you who are highly favored!” And thus she received the Word, and soon, in time, through the body's natural process, she gave birth to the dear Pearl. Come, then, you, too, dearly beloved, and let us chant the melody that has been taught us by the inspired harp of David and say, “Arise, O Lord, into Your rest, You, and the ark of Your sanctuary.” For the holy Virgin is truly an ark, made With gold both within and without, who has received the whole treasury of the Holy of Holies. “Arise, O Lord, into Your rest. Arise, O Lord, out of the bosom of the Father, in order that You may raise up the fallen race sakes He became poor” and chose extreme humiliation on behalf of the salvation of our nature, in His inherent goodness toward us. He who fulfilled the whole administration of unutterable mysteries of God's work in heaven in the bosom of the Father, and in the cave lay in the arms of the mother, reposed in the manger. Angelic choirs surrounded Him, singing of glory in heaven and of peace upon earth. In heaven He was seated at the right hand of the Father; and in the manger He rested, as it were, upon the cherubim. Truly, even there was His cherubic throne; there was His royal seat. Holy of the holy, and alone glorious upon the earth, and holier than the holy, was the manger where Christ our God rested. To Him be glory, honor, and power, together with the Father undefiled and the altogether holy and quickening Spirit, now and ever and unto the ages of the ages. Amen. - St. Gregory Thaumaturgus
