Elder St. Porphyrios on our Freedom
“The explanation which our faith gives is as follows: evil exists and comes from the devil. Within us we have both the evil spirit and the good spirit and they battle with each other. ‘Either he will hate the one and love the other; or else he will cling to the one and despise the other. You cannot serve God and mammon. ‘That is, within us a struggle between good and evil takes place. But in this struggle a person is free to decide and to choose. Consequently it is not God who pre-ordains and decides, but man’s free will. God in His omniscience knows in all precision not simply beforehand, but before the creation of the world, that this person, for example, will commit a murder when he is thirty years old. But the person in his freedom of will (a gift which God gave the person and which he perverted) acts of his own volition. God is not the cause, nor does he pre-ordain us for that end. His omniscience does not constrain us. He respects our freedom He does not abolish it. He loves us; he does not make us slaves; He gives us worth.
