We ought to learn the virtues through practicing them, not merely through talking about them, so that by acquiring the habit of them we do not forget what is of benefit to us.
Acquire humility, which scorches the demons, obedience, which opens the door for the Son of God to enter a man, faith which saves a man, hope which makes him unashamed; and love which lets not a man fall away from God.
If therefore holy men, even when they do mighty things, think themselves worthless, what must be said of those who, without fruit of virtue, are yet swollen with pride? But any works, although they be good, are as nothing unless seasoned with humility. A great deed done boastfully, lowers rather than uplifts a man. He who would gather virtue without humility, carries dust in the wind; and where he seems to possess something, from the same is he blinded and made worse.
Let us have recourse to humility on all occasions; for the humble lie prone on the ground, and how can a man fall if he lies on the ground? But a man who stands on a height can easily fall.
Where there is pride there cannot be grace, and if we lose grace we also lose both love of God and assurance in prayer. The soul is then tormented by evil thoughts and does not understand that she must humble herself and love her enemies, for there is no other way to please God.
For, just as it is good to recall ones sins, so it is also good to forget ones good deeds. Why is this? Because remembrance of our good deeds puffs us up with arrogance, whereas remembrance of our sins curbs and humbles our mind; the former makes us more sluggish, but the latter makes us more diligent. Indeed, those who do not think that they have anything good become more eager to acquire what is good, whereas those who reckon that they have stored up a great deal of merchandise, confident they have an abundance of this, do not display much zeal for obtaining more of it.
Do you see the humility of the saints? How their hearts were moved? Even when God sent them to help other people, they did not agree to this easily out of humility and to avoid glory. Like a man wearing an all-silk garment, if someone throws a dirty rag at him he leaves so as not to ruin his expensive clothes, it is with the saints, who are dressed in virtues, and avoid human glory in order not to be defiled.
If we prefer not to empty out all we possess for the love of God, let us at least not callously hold on to everything ourselves. Let us do something, then humble ourselves before God and obtain forgiveness from Him for what we have failed to do. For His love for mankind makes up for our omissions...
In so much as you sincerely compel yourself to do God's commandments, an understanding of the infirmity of your being will be born in you, and in as much as you have this understanding, one of the basic Christian virtues, humility, will in turn be born. God's grace is given only for humility, not for works, although humility is engendered by works. This is the law of true asceticism.
After careful clearing, we need to sow the good seed so that it may produce good fruit. The person who wants to sow his, field must also hide the seed, dipping it into the earth as otherwise the birds will come and take it, and it will be lost. After that, he awaits the mercy of God until He sends rain and the seed grows. Even if the farmer works hard, clearing, preparing and sowing, if God does not give rain for the seeds, his entire labor is in vain. We also need the same. Even if we on one occasion do something good, we must cover it with humility and show to God our weakness, asking Him to bless our labor since otherwise it is in vain.
