Do all in your power not to fall, for the strong athlete should not fall. But if you do fall, get up again at once and continue the contest. Even if you fall a thousand times because of the withdrawal of God's grace, rise up again each time, and keep on doing this until the day of your death. For it is written, 'If a righteous man falls down seven times' - that is, repeatedly throughout his life - 'seven times shall he rise again' [Prov. 24:16].
Let us be sure, then, that God will not give spiritual gifts - the gifts of understanding, of faith, of love, of purity, of prophecy, of working wonders, of power over demons, of insight, of sight of the heavenly world, to him who has gambled with and made evil use, like the Prodigal Son, of the gifts of bodily health, honor, wealth, success among men or knowledge of this material world, or some other skill or capacity.
In the beginning, there is struggle and a lot of work for those who come near to God. But after that, there is indescribable joy. It is just like building a fire: at first it's smoky and your eyes water, but later you get the desired result. Thus we ought to light the divine fire in ourselves with tears and effort.
While you are on earth, regard yourself as a guest of the Host, that is, of Christ. If you are at table, He honors you thus. If you breathe the air, you breathe His air. If you bathe, you bathe in His water. If you travel, you travel around His earth. If you accumulate goods, you accumulate what is His; if you squander them, you squander what is His. If you are influential, you are so by His permission. If you are in company with others, you are with His other guests. If you are in the countryside, you are in His garden. If you are alone, He is present. If you set off anywhere, He sees you. If you do anything, He has it in mind. He is the most careful Host whose guest you have ever been. And be, in your turn, careful towards Him. A good host merits a good guest. These are all simple words, but they speak a great truth to you. All the saints knew this truth, and ordered their lives accordingly. Therefore the immortal Host rewarded them with eternal life in heaven and with glory on earth.
And finally, did not the Lord Jesus Himself begin His divine ministry of the salvation of mankind with a long, forty day fast? And did not He, in this way, clearly show that we must make a serious beginning to our life as Christians with fasting? First, the fast, and then all the rest comes together with, and through, the fast. By His own example, the Lord showed us how great a weapon fasting is. With this weapon, He vanquished Satan in the wilderness, and with it was victorious over the three chief satanic passions with which Satan tempted Him: love of ease love of praise and love of money. These are three destructive greeds, the three greatest traps into which the evil enemy of the human race lures Christ's soldiers.
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.
Suppose you have ordered yourself not to eat fish; you will find that the enemy continually makes you long to eat it. You are filled with an uncontrollable desire for the thing that is forbidden. In this way you can see how Adam's fall typifies what happens to all of us. Because he was told not to eat from a particular tree, he felt irresistibly attracted to the one thing that was forbidden him.
If your heart has been softened either by repentance before God or by learning the boundless love of God towards you, do not be proud with those whose hearts are still hard. Remember how long your heart was hard and incorrigible. Seven brothers were ill in one hospital. One recovered from his illness and got up and rushed to serve his other brothers with brotherly love, to speed their recovery. Be like this brother. Consider all men to be your brothers, and sick brothers at that. And if you come to feel that God has given you better health than others, know that it is given through mercy, so in health you may serve your frailer brothers.
If a man only theorises about God, then he is helpless, utterly helpless, when confronted by an evil spirit. An evil spirit laughs at feeble worldly theorising. But as soon as a man begins to fast and to pray to God, the evil spirit becomes filled with inexpressible fear.
A single word made the thief pure and holy, despite all his previous crimes, and brought him into paradise (cf. Luke 23:42-43). A single ill-advised word prevented Moses from entering the promised land (cf. Num. 20:12). We should not suppose, then, that garrulity is only a minor disease. Lovers of slander and gossip shut themselves out of the kingdom of heaven.

The body can neither love nor hate. Neither can a body fall in love with a body. The capability for love belongs to the soul. When the soul is in love with the body, that is not love but desire, lust. When the soul is in love with the soul, but not through God, that is either admiration, or pity. However, when the soul, through God loves the soul, without consideration for the appearance of the body - beauty or ugliness - that is love. That is true love. For in love is life.
He who believes in Christ is not judged, for he judges himself, and sets his feet aright to follow the light that goes before him. As a man in deep darkness adapts his step to the candle in his hand, so also he who believes in Christ; that is, he who is set to follow after Christ as the light in the darkness of life.
