What is the source from which man's will can draw suitable principles of guidance? For a non-believer, an answer to this is extremely difficult and essentially impossible. Are they to be drawn from science? In the first place, science is interested primarily in questions of knowledge and not morals, and secondly, it does not contain anything solid and constant in principles because it is constantly changing. From philosophy? Philosophy teaches about the relativity of its truths and does not claim their unconditional authority. From practical life? Even less. This life itself is in need of positive principles which can remove from it unruly and unprincipled conditions. But while the answer to the present question is so difficult for non-believers, for a believing Christian the answer is simple and clear. The source of good principles is God's will, and this is revealed to us in the Savior's teaching, in His Holy Gospel. It alone has an unconditional, steadfast authority in this regard; and it alone teaches us self-sacrifice and Christian freedom, Christian equality and brotherhood (a concept stolen by those outside the Faith). The Lord Himself said of true Christians, 'Not everyone who says to Me, Lord, Lord, will enter the kingdom of heaven, but he who does the will of My Father' (Matt. 7:21).
A certain brother asked the Abbot Poemen, saying, 'What am I to do, Father, for I am troubled in sadness?' The old man said to him, 'Look to no man for aught, condemn no man, disparage no man: and God shall give thee rest.'
One must endeavor to read through the writings of the Fathers, and strive as much as possible, according to one’s strength, to fulfill what they teach, and in this fashion, little by little ascend from the ascetic life to the perfection of the contemplative.
A certain priest, an unfortunate man who had no knowledge of divine experience like that of St. Silouan, said to another person, 'I wonder why they go to him, he does not read anything.' The other replied, 'He does not read anything, but he practices everything, unlike those who read a lot but do not do a thing.'
Never neglect reading from the Fathers. You will benefit greatly because the saints set an example for you. You see your faults and failings as if in a mirror and correct your life. Reading is like light in the darkness.
One should nourish the soul with the word of God: for the word of God, as St. Gregory the Theologian says, is angelic bread, by which are nourished souls who hunger for God. Most of all, one should occupy oneself with reading the New Testament and the Psalter, which one should do standing up. From this there occurs an enlightenment in the mind, which is in the mind, which is changed by a Divine change.
We are told to draw the waters of life from the sources of the Divine Writings which alone can extinguish the passions that plague us and set us on the road to intellectual truth.
The more one reads and studies the Bible, the more he finds reasons to study it as often and as frequently as he can. According to St. John Chrysostom, it is like an aromatic root, which produces more and more aroma the more it is rubbed.
Do not say...that one or two books is sufficient for instructing the soul. After all, even the bee collects honey not from one or two flowers only, but from many. Thus also he who reads the books of the Holy Fathers is instructed by one in faith or in right thinking, by another in silence and prayer, by another in obedience and humility and patience, by another in self-reproach and in love for God and neighbor; and, to speak briefly, from many books of the Holy Fathers a man is instructed in life according to the Gospel.
Whoever is experienced in the spiritual interpretation of Scripture knows that the simplest passage is of a significance equal to that of the most abstruse passage, and that both are directed to the salvation of man.
The view we take of our Savior's dispensation is the view of the holy fathers who preceded us. By reading their works we equip our own mind to follow them and to introduce no innovation into Orthodoxy.
