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.
When we live according to the moral principles of our faith, those around us may respond in three possible ways. First, they may be so impressed by the example of our goodness, and so envious of the joy which it brings, that they want to join us and become like us. That is the response which we most earnestly desire. Second, they may be indifferent to us, because they are so bound up with their own selfish cares and concerns; although their eyes may perceive our way of life, their hearts are blind, so we are unable to stir them. Third, they may react against us, feeling threatened by our example and even angry with us; thus they will cling even more firmly to their material possessions and selfish ambitions, and slander us at every opportunity. Naturally, we dread this third type of reaction, because we want to live in peace with our neighbors, regardless of their personal beliefs and values. But if no one reacts to us in this way, we must wonder whether we are truly fulfilling the commandments of Christ.
When you are generous to another person, you are not bestowing a gift, but repaying a debt. Everything you possess materially comes from God, who created all things. And every spiritual and moral virtue you possess is through divine grace. Thus you owe everything to God. More than that, God has given you his Son, to show you how to live: how to use your material possessions, and how to grow in moral and spiritual virtue. We may say that your material and spiritual possession cost God nothing; God created the universe in order to express His glory. But the gift of his Son was supremely costly, because His Son suffered and died for our sakes. The agony of Christ on the cross is the measure of how much God loves us. For this reason we should take none of our gifts-- material or spiritual --for granted; day by day we should give thanks to God for what He has bestowed on us. Once this spirit of gratitude infuses us, we shall see generosity for what it is. When we help someone in need, we shall be saved from any temptation to take pride in our actions. On the contrary, we will regard our act as no more than a small token of appreciation for all that we have received - or, more precisely, the repayment of a tiny fraction of God's blessings.
When an archer desires to shoot his arrows successfully, he first takes great pains over his posture and aligns himself accurately with his mark. It should be the same for you who are about to shoot the head of the wicked devil. Let us be concerned first for the good order of sensations and then for the good posture of inner thoughts.
Even if we have thousands of acts of great virtue to our credit, our confidence in being heard must be based on God's mercy and His love for men. Even if we stand at the very summit of virtue, it is by mercy that we shall be saved.
Though you pray to God every hour, though you have such faith that you can move mountains, even though you give away all of your belongings to the needy, and give your body to be burned, - if you do not practice forgiveness and do not wish to forgive your enemy, then all is in vain, for in such circumstances neither prayer, nor faith, nor charity, will save you, in short, nothing will save you.
What profit is there in present delight; here today, tomorrow fled? Today a shining flower; tomorrow scattered dust. Today a bright fire; tomorrow dead ashes. But it is not so with spiritual things. They remain ever shining, ever flowering, each day a greater joy. These riches are never lost, never given up, never come to an end, never cause anxiety nor envy nor blame. They neither destroy the body nor corrupt the soul, nor awaken jealousy, nor provoke malice; as with earthly riches. This glory does not lead a man to senseless folly; does not inflame him, does not come to an end, does not fade. The rest and the delight of heaven remains, it goes on, ever unchanging and immortal. For it has no limit; it has no end. Let us, I beseech you, long for this life. For if we long for this life, we shall place no value on the things of the present time.
Self-accusation before God is something that is very necessary for us; and humility of heart is extremely advantageous in our lives, above all at the time of prayer. For prayer requires great attention and needs a proper awareness, otherwise it will turn out to be unacceptable and rejected, and `it will be turned back empty' to our bosom.
Wherefore, do not remember your good deeds, in order that God may remember them. Do thou first confess thy sins, it is written, that thou mayest be justified (Isaiah 43:26).
For Christians above all men are forbidden to correct the stumblings of sinners by force...it is necessary to make a man better not by force but by persuasion. We neither have authority granted us by law to restrain sinners, nor, if it were, should we know how to use it, since God gives the crown to those who are kept from evil, not by force, but by choice.
'If our prayer is not in harmony with our deeds, we labor in vain,' Abba Moses often told the young monks. 'How are we to accomplish such harmony?' they asked him one day. 'When we make that which we seek fitting to our prayer,' explained the saint. 'Only then can the soul be reconciled with its Creator and its prayer be acceptable, when it sets aside all of its own evil intentions.'
