In the book of Iisus/ Jesus, the son of Sirah/ Sirach [Ἰησοῦς υἱὸς Σιραχ], in 17, 18, LXX, we find this text: „He put His eye upon their hearts [ἔθηκεν τὸν ὀφθαλμὸν Αὐτοῦ ἐπὶ τὰς καρδίας αὐτῶν], [as] to show them the greatness of His things [δεῖξαι αὐτοῖς τὸ μεγαλεῖον τῶν ἔργων Αὐτοῦ]”. And what means here His eye? It means His glory. For only when He puts His glory over our hearts, we see the greatness of His glory, ie His divine things seen ecstatically.
When God commanded the light in Gen. 1, He saw that the light is good [Gen. 1, 4]. That it is proper for our existence. But here, at Gen. 1, 4, is the word about the created light, for that, from eternity, from God springs His uncreated light. And His uncreated light, seen ecstatically by the Holy men of God, is the glory of God from Sirah 17, 18, LXX.
How had seen Saint Adam at beginning, in Edem? He had seen in the glory of God, ie ecstatically. But when he sinned, then he began to see with bodily eyes, because he had seen that he was naked [γυμνὸς] [Gen. 3, 11]. And he did not refer, primarily, at the fact that he had no clothes, but at the fact that the sin had robbed him of the glory of God.
At our Baptism, we received the garment of the grace, which is interior, ie we received the glory of God. And if we feel His glory in us, then we can see ghostually, ie through the grace of the Holy Ghost. But for to see ghostually, we must live a holy life. And for to live holy on earth, we must see all things through God’s eyes, ie into His glory.
Therefore, the problem number one of the Orthodox life is the cleaning of passions. For, through this, we can see ghostually. And when we see ghostually, then we understand, on our measure, the mysteries of God from Church and from His entire creation.
But, if we do not see ghostually, we are ghostually blind. And for this we stop at letters, at forms, at appearances. Then we let ourselves spellbound, blinded by matter, for that we cannot look over it. But if we come to feel that we delved in the earthly things, we go out anytime from the pit of our life through repentance. For the repentance is our resurrection from the dead.
