To wage war only with the sins that make their appearance as actual deeds would be just as unsuccessful as cutting down weeds in a garden instead of digging them up at the root and throwing them out. Sins appear as inevitable outgrowths from their roots, the passions of the soul.
Do not love the world, all the deceit of the world, for it passes by quickly along with all its pleasures. Only he who does the will of God remains unto the ages.
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.
Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
Cultivate the Jesus Prayer and a time will come when your heart will leap with joy, just as it does when you are about to see a person who you love very much.
My child, man's life is full of sorrow because he is in exile. Do not seek perfect rest. Since our Christ bore His Cross, we shall bear ours, too. If we endure all afflictions, we shall receive grace from the Lord. The Lord allows us to be tempted, so that He can test the zeal and love we have for Him. Therefore, patience is needed. Without patience a person does not obtain experience, acquire spiritual knowledge, or attain any measure of virtue and perfection.
Abba Or used to say this, 'Do not speak in your heart against your brother like this: 'I am a man of more sober and austere life than he is,' but put yourself in subjection to the grace of Christ, in the spirit of poverty and genuine charity, or you will be overcome by the spirit of vainglory and lose all you have gained. For it is written in the Scriptures: 'Let him who stands take heed lest he fall.' (I Corinthians 10:12) Let your salvation be founded in the Lord.'
God always helps. He always comes in time, but patience is necessary. He hears us immediately when we cry out to Him, but not in accordance with our own way of thinking. You think that your voice did not immediately reach the saints, our Panagia, and Christ. On the contrary, even before you cried out, the saints rushed to your aid, knowing that you would call upon them and seek their God-given protection. However, since you do not see beyond what is apparent and do not know how God governs the world, you want your request to be fulfilled like lightning. But this is not how things are. The Lord wants patience. He wants you to show your faith. You cannot just pray like a parrot. It is necessary also to work towards whatever one prays for, and then to learn to wait.
With pain and tears you will receive grace, and again with tears and joy and thanksgiving, with fear of God you will keep it. With zeal it is drawn. With coldness and negligence it is lost.
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.
The life of a man is leavened with afflictions and torments. When you see a little joy in your soul, know that it is a phone call telling you to endure the affliction that will come.
