From my other blog, Wisdom!: Readings from the Fathers of the Church:
The mystery hidden from the ages (Col 1:26) and from the nations is now revealed through the true and perfect incarnation of the Son and God. For he united our nature to himself in a single hypostasis, without division and without confusion, and joined us to himself as a kind of first fruits. This holy flesh with its intellectual and rational soul came from us and is ours. He deemed us worthy to be one and the same with himself according to his humanity. For we were predestined before the ages (cf Eph 1:11-12) to be in him as members of his body. He adapted us to himself and knitted us together in the Spirit as a soul to a body and brought us to the measure of spiritual maturity derived from his fullness. For this we were created; this was God's good purpose for us before the ages. But this renewal did not come about through the normal course of things, it was only realized when a wholly new way of being human appeared. God had made us like himself and allowed us to participate in the very things that are most characteristic of his goodness. Before the ages he had intended that man's end was to live in him, and to reach this blessed end he bestowed on us the good gift of our natural powers. But by misusing our natural powers we willingly rejected the way God had provided and we became estranged from God. For this reason another way was introduced, more marvelous and more befitting of God than the first, and as different from the former as what is above nature is different from what is according to nature. And this, as we all believe, is the mystery of the mystical sojourn of God with men. For if, says the divine apostle, the first covenant had been blameless, there would have been no occasion for a second (Heb 8:7). It is clear to all that the mystery accomplished in Christ at the end of the age (Heb 9:26) shows indisputably that the sin of our forefather Adam at the beginning of the age has run its course.

It is evident that every person who participates in virtue as a matter of habit unquestionably participates in God, the subtance of the virtues. Whoever by his choices cultivates the good natural seed shows the end to be the same as the beginning and the beginning to be the same as the end. Indeed the beginning and the end are one. As a result he is in genuine harmony with God, since the goal of everything is given in its ultimate goal. As to the beginning, in addition to receiving being itself, one receives the natural good by participation: as to the end, one zealously traverses one's course toward the beginning and source without deviation by means of one's good will and choice. And through this course one becomes God, being made God by God. To the inherent goodness of the image is added the likeness (cf. Gen 1:26) acquired by the practice of virtue and the exercise of the will. The inclination to ascend and to see one's proper beginning was implanted in man by nature.
In such a person the apostolic word is fulfilled: In him we live and move and have our being (Acts 17:28). For whoever does not violate the logos of his own existence that pre-existed in God is in God through diligence; and he moves in God according to the logos of his well-being that pre-existed in God when he lives virtuously; and he lives in God according to the logos of his eternal being that pre-existed in God. On the one hand, insofar as he is already irrevocably one with himself in his dispositions, he is free of unruly passions. But in the future age when graced with divinization, he will affectionately love and cleave to the logoi already mentioned that pre-existed in God, or rather, he will love God himself, in whom the logoi of beautiful things are securely grounded. In this way he becomes a "portion of God," insofar as he exists through the logos of his being which is in God and insofar as he is good through the logos of his well-being which is in God; and insofar as he is God through the logos of his eternal being which is in God, he prizes the logoi and acts according to them. Through them he places himself wholly in God alone, wholly imprinting and forming God alone in himself, so that by grace he himself is God and is called God. By his gracious condescension God became man and is called man for the sake of man and by exchanging his condition for ours revealed the power that elevates man to God through his love for God and brings God down to man because of his love for man. By this blessed inversion, man is made God by divinization and God is made man by hominization. For the Word of God and God wills always and in all things to accomplish the mystery of his embodiment.

For to have offended God is more distressing than to be punished. But now we are so wretchedly disposed, that, were there no fear of hell, we should not even choose readily to do any good thing. Wherefore were it for nothing else, yet for this at least, we should deserve hell, because we fear hell more than Christ. . . . But since we feel otherwise, for this reason are we condemned to hell: since, did we but love Christ as we should love Him, we should have known that to offend Him we love were more painful than hell. But since we love Him not, we know not the greatness of His punishment. And this is what I bewail and grieve over the most! And yet what has God not done, to be beloved of us? What hath He not devised? What hath He omitted? We insulted Him, when He had not wronged us in aught, but had even benefited us with blessings countless and unspeakable. We have turned aside from Him when calling and drawing us to Him by all ways, yet hath He not even upon this punished us, but hath run Himself unto us, and held us back, when fleeing, and we have shaken Him off and leaped away to the Devil. And not even on this hath He stood aloof, but hath sent numberless messengers to call us to Him again, Prophets, Angels, Patriarchs: and we have not only not received the embassy, but have even insulted those that came. But not even for this did He spew us out of His mouth, but like those slighted lovers that be very earnest, He went round beseeching all, the heaven, the earth, Jeremiah, Micah, and that not that He might weigh us down, but that He might speak in behalf of His own ways (Is. i. 2; Jer. ii. 12; iii. 12; etc.; Mic. vi. 1): and along with the prophets He went also Himself to those that turned aside from Him, being ready to submit to examination, and deigning to condescend to a conference, and drawing them that were deaf to every appeal into a disputation with Himself. For He saith, "O my people, what have I done unto thee, and wherein have I wearied thee? Answer me." (Mic. vi. 3.) After all this we killed the Prophets, we stoned them, we did them other cruel wrongs without number. What then? In their place He sent no longer Prophets, no longer Angels, no longer Patriarchs, but the Son Himself. He too was killed when He had come, and yet not even then did He quench His love, but kindled it even more, and keepeth on beseeching us, after even His own Son was killed, and entreating us, and doing all things to turn us unto Himself. And Paul crieth aloud, saying, "Now then we are ambassadors for Christ, as though God did beseech you by us: be ye reconciled to God." (2 Cor. v. 20.) None of these things however reconciled us. Yet not even then did He leave us, but keeps on both threatening hell, and promising a kingdom, that even so He may draw us unto Himself. But we be still in an insensible mood. What can be worse than this brutishness? For had a man done these things, should we not many times over have let ourselves become slaves to him? But God when doing so we turn us away from! O what listlessness! O what unfeelingness We that live continually in sins and wickednesses, if we happen to do any little good, like unfeeling domestics, with what a niggardly spirit do we exact it, and how particular are we about the recompense made, if what we have done has any recompense to come of it. And yet the recompense is the greater if you do it without any hope of reward. Why saying all this, and making exact reckoning, is language fitter for an hireling than a domestic of willing mind. For we ought to do everything for Christ's sake, not for the reward, but for Him. For this also was why He threatened hell and promised the kingdom, that He might be loved of us. Let us then so love Him as we ought to love Him. For this is the great reward, this is royalty and pleasure, this is enjoyment, and glory, and honor, this is light, this is the great happiness, which language (or reasoning) cannot set before us, nor mind conceive.
--St. John Chrysostom, Homily V on Romans

A profound and hidden mystery is the fall of man. It is quite impossible for a person to understand it by his own powers. This is because among the consequences of the fall is mental blindness, which prevents the mind from seeing the depths and darkness of the fall. Our fallen state deceptively appears to be a state of triumph, and the land of exile seems to be an exceptional field of progress and enjoyment. Gradually God discloses the mystery to those ascetics who serve Him sincerely and with all their soul.
What a different picture, brethren, and how terrible is the sight that meets our gaze when the mystery is disclosed to us! When by divine guidance the abysses of hell are laid bare in the depth of the heart, how is it possible not to be filled with fear! How can we not be filled with fear especially when our with weakness and infirmity is proved to us by countless bitter experiences! How is it possible not to be filled with horror at the thought that some deadly passion can lie hidden in the heart for a long time, then suddenly appear and ruin a person for ever! That is true. But whoever fears sin, whoever does not trust himself, is not in danger from sin.
