The most important thing during illness is to offer to God patience and thanksgiving for His merciful visitations. Sickness purifies sins and gives one time to meditate on the past.
You are, I am sure, aware that for you penitence is now no longer limited to disclosing your sins to your confessor, but that you must now bear your sins in mind always, until your heart nearly breaks with their ugly load; and would break, were it not for your firm faith in the mercy of our Lord.
Our achievements must never loom large in our eyes; only our failures. But this must never lead us to despondency - the constant temptation - only to humility.
Every one of us solemnly promises at his consecration to abide by our Faith and to obey the canons of the Holy Fathers, vowing before God to keep Orthodoxy inviolate from the temptations and errors which creep into the Church's life.
The best medicine for pride, man’s greatest sickness of soul, is humility. Words cannot describe or explain it, but the Fathers say that he who strives hard to live according to the precepts of our Lord, and is fully aware of his own sins, acquires it steadily. Therefore be very careful never to think yourself good, or the least bit better than others.
While warning our children of the necessity of protecting themselves from social phenomena and habits which might attract them into the sin of our times, we beg them to look for direction in their lives and not to the evil of perverted, faithless humanity, but to that Light of the World which we have in the holy Church. The stronger the evil surrounding us, the more we must oppose to it the power of good by strengthening and developing our life in the Church and by practicing acts of love. Orthodox families must make an effort to form circles of acquaintances and friends from among the people of their own faith and culture, united around their parish church and the grace-filled life of the Church.
Wherever we are and whatever our circumstances, the enemy always tries to prevent us from actively responding to the call. Pray for help. For help that you may never fail to respond. And beware lest, having received help and having done the right deed because of it, you should grow proud and acquire the habit of condemning others, in the secret chambers of your heart. Beware! For this would make all the fruits of your good works wither.
In answer to your question as to what constitutes a happy life, whether splendor, fame and wealth, or a quiet, peaceful, family life, I will say that I agree with the latter, but will add the following: A life lived in humility and with an irreproachable conscience brings peace, tranquility, and true happiness. But wealth, honor, glory and exalted position often serve as the cause of a multitude of sins, and such happiness is not one on which to rely.
Without humility no other virtue is possible, for if man does not fulfill virtue in a spirit of humility, he will inevitably fall into God-opposing pride, and will fall away from God’s mercy.
When we are incapable of scaling the peaks of virtue, all we have to do is to descend into the ravine of humility. Our humility is our surest intercessor before the face of the Lord.
Fasting needn't be limited to abstinence from food alone, because true fasting is departure from evil deeds. Forgive your neighbor any insult, abstain from causing your neighbor offence, abstain from irritation, from senseless sorrows, from fear, wrath, and so on. ‘True fasting is alienation from evil, temperance of the tongue, setting aside of wrath, casting out of lust, idle talk, lies, and oath-breaking’…This is a true and pleasing fast for the Lord. Departing from these vices and from a corrupt state is what comprises a true fast.
