Fr. V.C Samuel of eternal memory had this to say
response from his book - 'An Orthodox Catechism on the Faith and Life of the Church' on the'Need of Divine Economy for Human Salvation'
'Man is a creature of God, endowed with creaturely freedom. As a creature, hehas a beginning and the possibility of an end. Yet, unlike other creatures,he/she is created to attain eternal life, which God grants. To gain this goal,man is called to live on earth in communion with the Creator and follow His way,using his creaturely autonomy. However, man took advantage of his personal freedom to follow his own plan in life. This led to his fall from the Source ofEternal life, to which he had to be restored. This restoration required anabsolute surrender to God on the part of man, which was possible only by GodHimself helping man to do it. Therefore the coming together of God the Son andman into union was necessary, and God accomplished it in Jesus Christ'
