Every action, therefore, and performance of miracles by Christ are most great and divine and marvelous: but the most marvelous of all is His precious Cross. For no other thing has subdued death, expiated the sin of the first parent, despoiled Hades, bestowed the resurrection, granted the power to us of contemning the present and even death itself, prepared the return to our former blessedness, opened the gates of Paradise, given our nature a seat at the right hand of God, and made us the children and heirs of God, save the Cross of our Lord Jesus Christ. For by the Cross all things have been made right.
A little fire softens a large piece of wax. So, too, a small indignity often softens, sweetens and wipes away suddenly all the fierceness, insensibility & hardness of our heart.
Let us observe and we shall find that the spiritual trumpet serves as an outward signal for the gathering of the brethren, but it is also the unseen signal for the assembly of our foes. So some of them stand by our bed, and when we get up urge us to lie down again: 'Wait,' they say, 'till the preliminary hymns are finished; then you can go to church.' Others plunge those standing at prayer into sleep. Some produce severe, unusual pains in the stomach. Others urge us on to make conversation in church. Some entice the mind to shameful thoughts. Others make us lean against the wall as though from fatigue. Sometimes they involve us in fits of yawning. Some of them bring on waves of laughter during prayer, thereby desiring to stir up the anger of God against us. Some force us to hurry the reading or chanting merely from laziness; others suggest that we should chant more slowly for the pleasure of it; and sometimes they sit at our mouths and shut them, so that we can scarcely open them. He who reckons with feeling of heart that he stands before God in prayer shall be an unshakeable pillar, and none of the aforesaid demons will make sport of him.
If a person swallows too much food, he is inviting impure thoughts. If he mortifies the stomach, he is creating pure thoughts. Often a lion if it is caressed becomes domesticated, whereas the more you coddle the body, the more it goes wild.
One should not ponder divine matters on a full stomach, say the ascetics. For the well-fed, even the most superficial secrets of the Trinity lie hidden.
By holy baptism original sin is expunged, as also sins committed before baptism. It also eliminates the violent power sin has over us till rebirth; it gives us the grace of the Holy Spirit by which we are united with God in Christ, and we receive power to subdue and conquer sin. For the simple reason that we are not delivered from the struggle with sin, we cannot be entirely free from sin during the whole of our earthly life, and even the righteous man may fall seven times (i.e. often) and rise again by repentance, says Scripture (Prov. 24:16). He falls on account of his weakness and limitations, because he does not always notice sin which subtly and imperceptibly rears its head from his fallen nature, and which is artfully and imperceptibly offered and suggested by fallen spirits. Repentance becomes his secure possession, his constant weapon, his invaluable treasure. By repentance the righteous man maintains his fellowship with Christ. He is healed by repentance from the wounds caused by sin.
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.
In order to remain in vigilance, it is necessary to guard the freshness and brightness of the mind with all care. The mind becomes darkened from imprudent use of food, drink and sleep, from much talking, from distraction and from worldly cares. Attend to yourselves, said the Lord, be on your guard and take care that your hearts are never weighed down, dulled and depressed by self-indulgence, overeating and drinking, or worldly cares and pleasures, lest that day (the day of Christ's dread judgment, the last day of the world) catch you unawares. For it will spring like a trap upon all who are living on the face of the earth. So watch and pray at all times for the strength to escape or survive all that is going to happen, and to stand before the Son of Man.
Spiritual activity embodies Christ in our soul. This involves continual remembrance of the Lord: you hide Him within, in your soul, your heart, your consciousness.
As a ray of sun, passing through a crack, lights everything in the house and shows up even the finest dust, so the fear of the Lord, entering a man's heart, reveals to him all his sins.
In the grim struggle with the invisible enemies of our salvation, the supreme weapon is the prayer of Jesus. `All the nations' - the vociferous and wily demons are called nations - `surround me,' says David, `and in the name of the Lord I repulsed them. They encircled and surrounded me like bees, and they burnt like fire among thorns; and in the name of the Lord I repulsed them' (Ps. 117:10-12). With the name of Jesus flog the foes, because there is no stronger weapon in heaven or earth.
