To act 'according to one’s strength' means to use a little less than necessary both of food, and drink, and sleep... As for food, restrain yourself when you wish to eat a little more, and in this way you will always make use of it moderately.
When the blessed Eulogius saw an angel distributing gifts to the monks who toiled at all-night vigils, to one he gave a gold piece with the image of Our Lord Jesus Christ, to another a silver piece with a cross, to another a copper piece, to another a bronze piece, and to another nothing. The others who had remained in the church, left the church empty-handed. It was revealed to him that the ones who had obtained the gifts are those who toil at vigils and are diligent in prayers, supplications, psalms, chants, and readings. Those who received nothing or who left the church empty-handed are those who are heedless of their salvation, are enslaved to vainglory and the clamors of life, and stand feebly and lazily at vigils and whisper and jest.
Concerning fasting, do not grieve, as I have said to you before: God does not demand of anyone labors beyond his strength. And indeed, what is fasting if not a punishment of the body in order to humble a healthy body and make it infirm for passions, according to the word of the Apostle: 'When I am weak, then am I strong' (II Corinthians 12:10).
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.
The head of every good striving and the pinnacle of all corrections is to persevere in prayer, by which we may ever obtain, through entreaty of God, all the other virtues as well. By prayer those who are worthy partake of the sanctity of God and spiritual activity and the union of the mind with the Lord in unutterable love. He who constantly forces himself to endure in prayer is roused by spiritual love to Divine fervor and flaming desire towards God, and he receives, according to his measure, the grace of spiritual, sanctifying perfection.
My son, says Scripture, if you come to serve the Lord, prepare your soul for trial, set you heart straight, and patiently endure (Eccles. 2:1-2). And elsewhere it is said: Accept everything that comes as good, knowing that nothing occurs without God willing it. Thus the soul that wishes to do God's will must strive above all to acquire patient endurance and hope. For one of the tricks of the devil is to make us listless at times of affliction, so that we give up our hope in the Lord. God never allows a soul that hopes in Him to be so oppressed by trials that it is put to utter confusion. As St. Paul writes: God is to be trusted not to let us be tried beyond our strength, but with the trial He will provide a way out, so that we are able to bear it (I Cor. 10:13). The devil harasses the soul not as much as he wants but as much as God allows him to. Men know what burden may be placed on a mule, what on a donkey, and what on a camel, and load each beast accordingly; and the potter knows how long he must leave the pots in the fire, so that they are not cracked by staying in it too long or rendered useless by being taken out of it before they are properly fired. If human understanding extends this far, must not God be much more aware, infinitely more aware, of the degree of trial it is right to impose on each soul, so that it become tried and true, fit for the kingdom of heaven?
A thick rope is composed of thin strands of hemp. One thin strand cannot hold you bound nor strangle you, for you will easily, with the lightest touch, break it and free yourself. But if a thick rope binds you, you will stay bound, and it will strangle you. You cannot easily break it and free yourself of it. As a thick rope is made from thin, weak strands, so men's passions are made up of smaller initial sins. The small, initial sins a man can still break and free himself of. But sin on sin, repeated, the weave becomes thicker and thicker until it becomes a passion, which masters a man as only it can do. You can neither cut it out easily nor cast it away from you nor be divorced from it. Oh, when will men guard themselves from these first sins? Then they would not have so much difficulty in freeing themselves from the passions.
A brother was insulted by his friend, but, desiring peace with him, went to him to be reconciled. But the other would not open the door to him and, abusing him from within, drove him away from the house. The brother complained to a spiritual elder, who said to him: 'In going to make peace with your brother, you have, all along the way, condemned him in your thoughts and justified yourself. I advise you, if your friend sins against you, to order your thoughts as though it were you who had
sinned against him, and then go to him, justifying him and condemning yourself in your thoughts.' The brother did this, and what happened? As soon as he drew near to his brother's house, the latter opened the door wide, ran to him and embraced him, and peace was made between them.
Christ did not spare even His holy apostles from temptation, and He therefore gave them grace. When Satan himself began to wreak his malice on the Apostle Paul, Paul prayed that Satan be removed from him. But the Lord replied 'My grace is sufficient for thee.' In other words, if you have to suffer at Satan's hands, My grace is sufficient for your suffering. If you have to struggle with Satan, again my grace is sufficient for you. If you desire to overcome Satan, again My grace is sufficient. Grace is a weapon that can be used for everything. Grace is stronger than all adversities, all assaults, all the powers of darkness. Grace is both unconquerable and conquering. Therefore, my brethren, we must pray to God to give us His almighty grace. Grace is God dwelling in us. Grace is the Kingdom of God within us. When God's grace is within us, then it is day in our souls. And the day means light, knowledge and freedom from fear. We cannot ask here on earth, my brethren, for a greater gift from God than divine grace. Should we receive the entire universe as a gift, it would be less than the grace of God.
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.
Watch constantly, learning to understand God's law, for this warms the heart with heavenly fire. Guard your lips from the idle word, or empty talk, lest the heart gets used to evil words.
