Pray simply. Do not expect to find in your heart any remarkable gift of prayer. Consider yourself unworthy of it. Then you will find peace. Use the empty cold dryness of your prayer as food for your humility. Repeat constantly: I am not worthy; Lord, I am not worthy! But say it calmly; without agitation.
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.
You ask for some way of completely eradicating irritability. The inclination to irritability is given us to use against sin, and we were never meant to use it against our fellow men. When we do, we act contrary to our true nature.
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.
When we see sinners we must always weep for ourselves first over their failure. Perhaps we have fallen in the same way; or we can fall, if we haven't yet. And if the judgment of the teaching office must always eradicate vices by the power of discipline, we must nevertheless make careful distinctions: we should be uncompromising about vice, but compassionate to human nature. If a sinner has to be punished, a neighbor has to be supported. When he has nullified what he has done by his repentance, our neighbor is no longer a sinner. With the righteousness of God he turns against himself, and what the divine righteousness reproves he punishes in himself.
A life lived in the world can be as good, in the eyes of God, as one spent in a monastery. It is indeed only the keeping of God's commandments, love of all, and a true sense of humility that matter, wherever we are.
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.
Wherever we are and whatever our circumstances, the enemy always tries to prevent us from actively responding to the call. Pray for help. For help that you may never fail to respond. And beware lest, having received help and having done the right deed because of it, you should grow proud and acquire the habit of condemning others, in the secret chambers of your heart. Beware! For this would make all the fruits of your good works wither.
When can someone understand human suffering? When he also suffers. When he goes through the same, he learns and understands the other person's suffering. Otherwise, he is callous and is not grieved, unless he happens to have a good nature. But all natural attributes merit neither honor nor dishonor; achievements and falls depend on our own free will.
Acts of charity, almsgiving and all the external good works do not suppress the arrogance of the heart; but noetic meditation, the labor of repentance, contrition and humility -- these humble the proud mind.
Now you become angry and fainthearted and grieved, thinking that the heavenly Father is slow in answering. But I tell you that this will also happen as you desire—it will definitely happen—but first it takes prayer with all your soul, and then you must wait. And when you have forgotten your request and have ceased asking for it, it will come to you as a reward for your patience and endurance. When you reach the verge of despair while praying and seeking, then the fulfillment of your request is near. Christ wants to heal some hidden passion within you, and this is why He delays in granting your request. If you obtain it sooner, when you demand it, your passion remains uncured within you. If you wait, you obtain your request and the cure of the passion. And then you rejoice exceedingly and give warm thanks to God Who arranges all things in wisdom and does everything for our benefit.
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.
