We are created with freedom so how do we fall? What is the reality? What are we? Who are we?

'The Theology of Illness' by Jean-Claud Larchet

"The body of the first Adam did not possess the materiality and heaviness that now characterize human bodies. ...Man was created with freedom, whether or not he preserved this state of grace depend on his free will. It was his responsibility to remain in a condition of incorruption and immortatlity with grace bestowed upon him, or to the contrary, to lose it by rejecting that grace.

Thus, when the Fathers affirm that man was created incorruptible and immortal, they do not mean that he could not become corrupt and die, but that he had the grace and free choice [indeed] the possibility not to corrupt himself and die. In order for his incorrputibility and immortality to be preserved and become permanent aspects of his being, man had to preserve the grace which God had given to him, and remain united to God throught the aid of the commandments issued for this purpose. (See, cf: St. Athanasius, St. Gregory of Nyssa, and St. Maximus and Gen 2:16-17).

In the words of St. Gregory Palamas: 'At the beginning, man was not only a creature of God, he was also, His son in the Spirit. This grace was accorded him together with his soul, through the vivifying Breath (cf. Gen 2.7)".

"The beginning of wisdom is the most sincere desire for instruction, and concern for instruction is love of her, and love of her is the keeping of her laws, and giving heed to her laws is assurance of immortality, and immortality brings one near to God; so the desire for wisdom leads to a kingdom" (Wisdom 6:17-20).
