What does it mean to be as wise as a serpent? When a serpent is attacked, it is willing to have much of its body severed, as long as it saves the head. So to be wise as a serpent means to be willing to lose everything - your wealth, your reputation, your friends - as long as you save your faith. Your faith is your head, by which you learn all truth; and by that truth your soul is set free. We should, however, recognize that the wisdom of the serpent is not enough; we must be honest and innocent as doves. Indeed it is the combination of wisdom and innocence that creates virtue. The person who is wise as a serpent can sustain the most terrible attacks and still continue to flourish as a disciple of Christ. The person who is innocent refuses to retaliate against those who make the attacks. To be as innocent as a dove means never to take revenge on those who wrong you or undermine you. Unless wisdom is tempered by innocence, one attack provokes another, and conflict continues without end. Unless innocence is tempered by wisdom, a person is so vulnerable that he will not even survive a single attack. Rest assured that no one can ever take away your faith; your wisdom guards against that. But be careful never to bear a grudge against anyone who does you wrong.
Many are the obstacles that stand in the way of pleasing God; for not merely poverty and obscurity but also riches and honor are trials for the soul. Indeed, to some extent even the solace and ease which grace bestows on the soul can easily become a temptation and a hindrance if the soul is not properly conscious of these effects of grace and does not enjoy them with great circumspection and understanding: for the spirit of evil tries to persuade the soul to relax now it possesses grace, and so contrives to implant in it sluggishness and apathy.
In the beginning there are a great many battles and a good deal of suffering for those who are advancing towards God and afterwards, ineffable joy. It is like those who wish to light a fire; at first they are choked by the smoke and cry, and by this means obtain what they seek -- as it is said, 'Our God is a consuming fire' -- so we also must kindle the divine fire in ourselves through tears and hard work.
Favors are given in exchange of faith. Grace is poured out, which faith receives. And as from a fountain some draw a little water in little vessels, and others draw more in bigger vessels, the fountain not distinguishing between the one vessel and the other, since it is the vessels, not the fountain, that measures the water, and each draws according to his measure; and as the splendor of light enters to a greater or less degree according to the dimensions of the window, so is grace received according to the measure of our desire.
And just as material fire, applied to the soft clay, changes it to hard pottery, so the fire of the Holy Spirit, when it penetrates our soul, though it should find it softer than the clay, yet it will make it more unyielding than iron. And the soul that a little while ago was stained with the mire of sin, is all at once more splendid than the sun.
Do not neglect the practice of the virtues; if you do, your spiritual knowledge will decrease, and when famine occurs you will go down into Egypt (Genesis 41:57, 46:6).
Do not the angels differ from us in this respect, that they do not want so many things as we do? Therefore the less we need, the more we are on our way to them; the more we need, the more we sink down to this perishable life.
They asked Abba Macarius, 'How should we pray?' And the old man replied, 'There is no need to speak much in prayer; often stretch out your hands and say, 'Lord, as you will and as you know, have mercy on me.' But if there is war in your soul, add, 'Help me!' and because he knows what we need, he shows mercy on us.'
In the matter of piety, poverty serves us better than wealth, and work better than idleness, especially since wealth becomes an obstacle even for those who do not devote themselves to it. Yet, when we must put aside our wrath, quench our envy, soften our anger, offer our prayers, and show a disposition which is reasonable, mild, kindly, and loving, how could poverty stand in our way? For we accomplish these things not by spending money but by making the correct choice. Almsgiving above all else requires money, but even this shines with a brighter luster when the alms are given from our poverty. The widow who paid in the two mites was poorer than any human, but she outdid them all.
Prayer is a great good if offered up from a thankful soul; if we are steadfast in it, so that whether we receive or do not receive what we pray for we at all times give thanks to God. For since He will sometimes grant what we ask and sometimes will not, in both cases it is to our gain... For oftentimes God will delay, not as denying our prayer, but in His wisdom seeking rather for our perseverance, and desiring to draw us nearer to Himself; as a loving father when asked by his son for something will often do; withholding consent, and not from the will to refuse, but rather to encourage him in steadfastness.
Lift up and stretch out your hands, not to heaven but to the poor; for if you stretch out your hands to the poor, you have reached the summit of heaven. But if you lift up your hands in prayer without sharing with the poor, it is worth nothing... Every family should have a room where Christ is welcomed in the person of the hungry and thirsty stranger. The poor are a greater temple than the sanctuary; this altar the poor, you can raise up anywhere, on any street, and offer the liturgy at any hour.
