Those who have sinned must not despair. Let that never be. For we are condemned not for the multitude of evils, but because we do not want to repent...
Bring before your eyes the blessings, whether physical or spiritual, conferred on you from the beginning of your life down to the present, and call them repeatedly to mind in accordance with the words: 'Forget not all His benefits' (Ps. 102:2). Then your heart will readily be moved to the fear and love of God, so that you repay Him, as far as you can. by your strict life, virtuous conduct, devout conscience, wise speech, true faith and humility - in short, by dedicating your whole self to God. When you are moved by the recollection of all these blessings which you have received through God's loving goodness, your heart will be spontaneously wounded with longing and love through this recollection or, rather, with the help of divine grace.
Peter was first given the keys, but then he was allowed to fall into the sin of denying Christ; and so his pride was humbled by his fall. Do not be surprised, then, if after receiving the keys of spiritual knowledge you fall into various evil thoughts. Glorify our Lord, for He alone is wise: through setbacks of this kind He restrains the presumption that we tend to feel because of our advance in the knowledge of God. Trials and temptations are the reins whereby God in His providence restrains our human arrogance.
'Then the devil left Him, and angels came and ministered to Him' (Matthew 4:11). It does not say that the angels were with our Lord during the actual time when He was being tempted. In the same way, when we are being tempted, God's angels for a time withdraw a little. Then, after the departure of those tempting us, they come and minister to us with divine intellections, giving us support, illumination, compunction, encouragement, patient endurance, joyfulness, and everything that saves and strengthens and renews our exhausted soul. As Nathaniel was told, 'You will see the angels ascending and descending upon the Son of man' (John 1:51); in other words, the ministry and assistance of the angels will be given generously to mankind.
Exercise patience out of love for your fellow man. Exercise patience in order to benefit your soul. For if you do not take your soul into consideration, you lose your patience.
When we return to prayer after a period of reading we find a rejuvenated and invigorated soul, stirred by the desire for God. The best form of prayer is one that implants the clearest idea of God in the soul and thus makes space for the presence of God within us. We become a temple of God when our continuous meditation on Him is not constantly interrupted by ordinary worries, and the spirit is not disturbed by unexpected emotions. Thus, in flight from all things, the spirit who loves God can approach God who drives out everything that leads us to evil, and holds steadfastly to everything that leads to virtue.
And when you pray, see that you ask not for what is alien to your life, and provoke the Lord. Ask not for money, not for human glory, nor power, nor for any of the things that pass away. But seek for the kingdom of God, and all that is needed for your body will be provided; as the Lord Himself has said: Seek ye the kingdom of God, and his justice, and all these things will be added unto you (Matthew 6:33).
The Law (as it is written in the Scriptures) was given to us by Angels and, both before and after the days of the Law, Angels guided our illustrious forefathers to God, either by declaring to them what they should do and leading them from error and an evil life to the straight path of truth, or by making known to them the Divine Law, or in the manner of interpreters, by showing to them holy Hierarchies, or secret visions of super-mundane Mysteries, or certain divine prophecies. Now if anyone should say that God has shown Himself without intermediary to certain holy men, let him know beyond doubt, from the most Holy Scriptures, that no man has ever seen, nor shall see, the hidden Being of God; but God has shown himself, according to revelations which are fitting to God, to His faithful servants in holy visions adapted to the nature of the seer.

Should you see your neighbor commit a sin, see that you think not only of his sin, but that you also think of what he does, and has done well, and doing this you will oftentimes find that he is better than you are; when you consider all he has done, and not a part. God does not judge a man on a part of his life only. He says: I knew their works and their thoughts; I come that I may gather them together. (Is. lxvi. 18).
Of the teachings and proclamations preserved in the Church, some we possess from written teaching, while others we have received in secret from the Tradition of the Apostles; these both have the same validity [ie. authority] for true religion. And no one will deny these points, at least if he is even moderately experienced in Church [matters].
The Spirit is not united to the soul by drawing near to its place (for how may what is corporeal draw near to what in incorporeal?), but through the withdrawal of the passions; which, drawing close to the soul, through its affection for the flesh, have drawn it away from its friendship with God. When a man becomes clean of the stain he received through sin, and has returned to his natural beauty, restoring to its former resemblance the royal image within him, only then may he draw near to the Paraclete (Holy Spirit).
Empty your mind of these two things: the belief that you are deserving of great things, or the thought that any man is beneath you. If you do this anger will never be permitted to rise up within you.
Forgive and pray, in order to live your life serenely. And do not do to others that which you do not want them to do to you, or return the evil which they have done to you.
