Because our nature is without sins in Christ and because by our following God we have become children of complacence who are attached to the Christ, and beloved sons, and the heaven is opened for us, so that even the Holy Spirit descends and dwells in us; through the Spirit we will ascend in heaven, when He who rised the Christ from the dead gives life to our mortal bodies because of His Spirit dwelling in us, having transformed our body of humiliation and given it the form of Christ's body of Glory. With that we became rich in immortality and were called again to heaven, our nature was elevated above all authorities and powers, to the throne at the right of the greatness in heaven.

Speech 16, On the Providence of the Incarnation, Patrologia Graeca 151.201

Διὰ τὴν ἐν Χριστῷ τῆς ἡμετέρας φύσεως ἀναμαρτησίαν καὶ τὴν πρὸς τὸν Θεὸν εὐπείθειαν τέκνα εὐδοκίας γεγόναμεν οἱ Χριστῷ κολλώμενοι, καὶ υἱοὶ ἀγαπητοί, καὶ ὁ οὐρανὸς ἠνέῳκται ἡμῖν ὡς καὶ ἐφ' ἡμᾶς τὸ Πνεῦμα κατιέναι τοῦ Θεοῦ καὶ μένειν ἐν ἡμῖν καὶ δι' αὐτοῦ κατὰ καιρὸν εἰς οὐρανοὺς ἀναφέρεσθαι ἡμᾶς, ἡνίκα ὁ ἐγείρας τὸν Χριστὸν ἐκ νεκρῶν ζωοποιήσῃ καὶ τὰ θνητὰ σώματα ἡμῶν διὰ τὸ ἐνοικοῦν αὐτοῦ Πνεῦμα ἐν ἡμῖν, μεταμορφώσας τὸ σῶμα τῆς ταπεινώσεως ἡμῶν, καὶ σύμμορφον ποιήσας τῷ σώματι τῆς δόξης τοῦ Χριστοῦ, δι' οὗ τὴν ἀθανασίαν ἐπλουτήσαμεν καὶ εἰς οὐρανοὺς ἀνεκλήθημεν καὶ ὑπεράνω πάσης ἀρχῆς καὶ ἐξουσίας ἐν δεξιᾷ τῆς μεγαλωσύνης ἐν οὐρανοῖς ἡ ἡμῶν ἐνεθρονίσθη φύσις.
