Remember always that, once we have decided consciously to strive after righteousness, we cannot escape catastrophes and sorrows, no matter where we are.
Not one of us can boast of having acquired humility: our actions, the whole of our life, prove the contrary. And where there is a lack of humility, pride is always present. Where light is wanting, darkness reigns.
Our achievements must never loom large in our eyes; only our failures. But this must never lead us to despondency - the constant temptation - only to humility.
Do not be despondent when fighting against the incorporeal enemy, but even in the midst of your afflictions and oppression praise the Lord, Who has found you worthy to suffer for Him, by struggling against the subtlety of the serpent, and to be wounded for Him at every hour; for had you not lived piously, and endeavored to become united to God, the enemy would not have attacked and tormented you.
The Church is the sure way to the life eternal; walk in it undeviatingly, hold fast to it, and you will gain the kingdom of heaven; but if you turn aside at the crossways of your own sophistry and unbelief, then you have only yourself to blame, you will go astray and be lost. ‘I am the way, the truth, and the life.’ (John 14:6)
If you do not experience in yourself the influence of the evil spirit, you will not know and you will not value as you should the goodness shown to you by the benevolence of the Holy Spirit; not having known the spirit that destroys, you also will not know the Life-giving Spirit. Only because of contrary opposites of good and evil, of life and death, we understand one and the other... 'Glory to God, the Wise and All-Good, that He permits the spirit of evil and death to tempt us and cause us suffering. Otherwise, how could we begin to value the consolation of Grace, the consolation of the Holy Spirit, the Comforter and Life-giver!'
Men who are leading a spiritual life see by the eyes of their heart how the devil lays his snares, how the angels guide us, and how the Lord, in His Sovereign power, allows the temptations, and how he comforts.
God's Scripture gives proof in numerous passages that man must undergo many disturbances in this life; and also that many consolations are at hand. With these, a spirit of sufficient vigor and awareness of the right should overcome present discomforts and look to those things that promise everlasting joy.
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.
The evil spirit tries to scatter prayer as if it were a sand heap, tries to turn the words into dry sand, without coherency or moisture - that is to say, without fervor of heart. Thus prayer may become either a house built on sand or a house built on a rock. Those build on sand who pray without faith, absently, coldly: such prayer is scattered of itself, and does not bring any profit to him who prays; those build on a rock who, during the whole time of their prayer, have their eyes fixed upon God, and pray to Him as to a living person, conversing face to face with them.
Most men not only bear Satan's burden willingly in their hearts, but they become so accustomed to it that they often do not feel it, and even imperceptibly increase it. Sometimes, however, the evil enemy increases his burden tenfold, and then they become terribly despondent and fainthearted, they murmur and blaspheme God's name. The usual means that men... take to drive away their anguish are... entertainments... But such means afterwards increase still more the anguish and weariness of their hearts. If, happily, they turn to God, then the burden is removed from their heart, and they clearly see that previously the heaviest burden was lying on their heart, though frequently they did not feel it.
Oh, what great happiness and bliss, what exaltation it is to address oneself to the Eternal Father. Always, without fail, value this joy which has been accorded to you by God's infinite grace and do not forget it during your prayers; God, the angels and God's holy men listen to you.
If you wish to correct any one from his faults, do not think of correcting him solely by your own means: you would only do harm by your passions, for instance, by pride and by the irritability arising from it; 'but cast thy burden upon the Lord,' and pray to God, Who 'searcheth the hearts and reins,' with all your heart, that He Himself may enlighten the mind and heart of that man. If He sees that your prayer breathes love, and that it really comes from the depth of your heart, He will infallibly fulfill the desire of your heart, and you yourself will soon tell, seeing the change that has taken place in him for whom you have prayed, that it is the work of the right hand of God, the most High.
The enemy of our salvation especially strives to draw our heart and mind away from God when we are about to serve Him, and endeavors to adulterously attach our heart to something irrelevant. Be always, every moment, with God, especially when you pray to Him. If you are inconstant, you will fall away from life, and will cast yourself into sorrow and straitness.
