As soon as you realize that you have sinned against the Lord, add no more wounds to your bruises. But if as a human you fall again, don't get despondent, don't despair. For how will the living Lord, Who told Peter to forgive seventy times seven in a day, not forgive us?
Christ told His friends, that is, His disciples, to beware of the leaven of the Pharisees and scribes, meaning by leaven their false pretence. For hypocrisy is a thing hateful to God, and abominated by man, bringing no reward, and utterly useless for the salvation of the soul, or rather the cause of its perdition. Though sometimes it may escape detection for a little, yet before long it is sure to be laid bare and bring disgrace upon them, like ill-featured women, when they are stripped of that external embellishment which they had produced by artificial means. Hypocrisy, therefore, is a thing foreign to the character of the saints. That it is impossible for those things that are done and said by us to escape the eye of the Deity, He showed by saying: “There is nothing covered that shall not be revealed; neither hid that shall not be known.” For all our words and deeds shall be revealed at the day of judgment.
First, one prays with the simplicity typical of beginners and by shedding copious tears. All this is due to the grace of God which is called purifying grace, which catches us like a fish-hook, and guides us towards repentance. For it is our God, Who is good in all and to all, Who finds us. He sees us. He invites Himself known to us first. Then we get to know Him, after He anoints us with His divine mercy. Hence, repentance, mourning, tears, and everything that happens to someone who repents, is all due to divine grace. This is purifying grace which cleanses man.
As therefore the Lord does nothing without the Father, for says He, 'I can of mine own self do nothing,' so do you, neither presbyter, nor deacon, nor layman, do anything without the bishop.
Faith is an eye that enlightens every conscience, and imparts understanding; for the Prophet saith, And if ye believe not, ye shall not understand (Is. vii, 9).
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.
Whatever gentleness you use in speaking with others, that very same gentleness will Christ use with you. With whatever measure you measure out to others, with that very same measure will He apportion out to you. Just as you forgive the failings of others, He forgives yours. With whatever love and gentleness you seek Him, likewise will He appear to you.
He who seeks grace from God must, above all, endure temptations and afflictions no matter how they come. Otherwise, if he becomes indignant and doesn't show enough patience during temptation, neither will grace manifest itself, nor will his virtue be perfected or will he be counted worthy of any spiritual gift.
Without temptations, pure souls are not known, virtue does not show, patience is not discernible. Without temptations, it is impossible for the soul to become healthy. They are the cleansing fire which makes the soul pure and bright.
The temptation comes in accordance with one’s stature. And you must endure in order to emerge victorious. Christ, Who sets the contest, allows temptations for this reason: so that we may gain victories against the enemy, be purged from passions, and be perfected.
The grace of the priesthood is one thing, the grace of the great schema is another, the grace of the Mysteries is different, and the action of grace in ascesis is also different. They all spring from the same source, but each one differs from the other in eminence and glory. The grace of repentance, which acts in those who struggle, is a patristic inheritance. It is a divine transaction and exchange in which we give dust and receive heaven. We exchange matter for the Spirit. Every drop of sweat, every pain, every ascesis for God is an exchange.
