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.
Fasting is an ordinance of the Church, obliging the Christian to observe it on specific days. Concerning fasting, our Savior teaches: 'When thou fastest, anoint thine head, and wash thy face; that thou appear not unto men to fast, but unto thy Father Who is in secret: and thy Father, Who seeth in secret, shall reward thee openly.' From what the Savior teaches we learn (a) that fasting is pleasing to God, and (b) that he who fasts for the uplifting of his mind and heart towards God shall be rewarded by God, Who is a most liberal bestower of Divine gifts, for his devotion. In the New Testament fasting is recommended as a means of preparing the mind and the heart for divine worship, for long prayer, for rising from the earthly, and for spiritualization.
The first duty of a Christian, of a disciple and follower of Jesus Christ, is to deny oneself. To deny oneself means to give up one's bad habits, to root out of the heart all that ties us to the world; not to cherish bad desires and thoughts; to quench and suppress bad thoughts; to avoid occasions of sin; not to do or desire anything from self-love but to do everything out of love for God. To deny oneself means, according to the Apostle Paul, to be dead to sin and the world, but alive to God.
The good Physician calls me and demands no payment, nor does he spill my blood. But my slothfulness prevents me from going to Him. He comes Himself to heal me, but always finds me engaged in acts that prevent His remedies from rendering me their healing power.
In no art do the artists judge the result of their work by the tools they use, but they await the work's completion and by it judge the art. Adopting such a practice with regard to food, not placing all your hope on fasting, but fasting moderately and according to the amount of your strength, strive toward mental activity. In this way you can avoid pride and will not spurn God's good works, sending up praises to God for everything.
The road into the Kingdom of Heaven was made by the Lord Jesus Christ, and He was the first one who traveled it. The Bible teaches that only he who follows Jesus can reach His Kingdom. But how can one follow Him? Hear what our Savior says about this: Whoever desires to come after Me, let him deny himself, and take up his cross, and follow Me (Mark 8:34). The words whoever desires mean that Christ does not compel anyone to follow Him. He has no need of the unwilling ones, but He desires that each person freely follow Him. Consequently, only those who willingly choose the Savior's path reach the Kingdom of Heaven.
Condemn only yourself, and you will not be condemned at His second and awful coming. From your whole heart remit the sins of whoever sins before you, and your Father who is in heaven will remit your sins.
Woe is he who knowingly chooses to sin with the intention to repent when morning comes, for he knows not what the coming day or the night that precedes it will bring.
Jesus Christ said that the Holy Spirit blows where it wills and you hear the sound of it, but cannot tell where it comes from and where it goes (Jn. 3:8). This means that a person cannot force the Holy Spirit to come to him or predict the time when He may decide to do so. You can only feel His touch when this happens. Indeed, the book of Acts states that when the Holy Apostles and other Christians received the gifts of the Holy Spirit, it was always unexpectedly. He seldom descends immediately on those beseeching Him but does so when it suits Him, as God, to do so. No one should attempt to foretell when or what gifts, if any, he will receive or to consider himself worthy of His descent! The Grace of the Holy Spirit is a gift of His endless mercy. And gifts by definition are given when it suits the giver, and only those deemed suitable by the giver.
In his concern for the salvation of souls, a pastor must remember that people also have physical needs which cry out for attention. One mustn’t preach the Gospel without showing love in action. At the same time, caution must be observed lest solicitude in meeting the physical needs of his neighbor swallow up the pastor’s attention altogether and serve to detract from his spiritual concerns. He must bear in mind the Apostle’s words: 'It is not reason that we should leave the word of God, and serve tables' (Acts 6:2). Everything must be directed towards acquiring the Kingdom of God and fulfilling Christ’s Gospel. True Christianity does not consist in intellectual abstract deliberations and teachings; rather, it is incarnate in life itself. Christ descended to earth not to instruct people in new forms of knowledge, but to call them to a new life. During our earthly life we prepare ourselves for eternity. The various circumstances and events of temporal life act to influence a man’s spiritual life. Those with strong characters are able to surmount the influence of their surroundings, while the weak give in to it. The strong in spirit are tempered by persecutions, while the weak fall. It is therefore necessary, insofar as possible, to create conditions in which as many people as possible can be spiritually formed.
Faith and love which are gifts of the Holy Spirit are such great and powerful means that a person who has them can easily, and with joy and consolation, go the way Jesus Christ went. Besides this, the Holy Spirit gives man the power to resist the delusions of the world so that although he makes use of earthly good, yet he uses them as a temporary visitor, without attaching his heart to them. But a man who has not got the Holy Spirit, despite all his learning and prudence, is always more or less a slave and worshipper of the world.
