St. Gregory the Dialogist wrote about what price we have to pay to acquire the Kingdom of Heaven. It has no exact price. Everyone has to give everything he has. The Apostle Peter gave his nets & received the heavenly kingdom; the widow gave two mites; whoever has a million dollars, let him give that; & whoever has nothing, let him give his freedom.
'God does not create crosses for people ie cleansing spiritual and physical sufferings. And however heavy that cross may be for that individual, the tree that produces its timber grows from the soil of his heart.' The Starets also said: 'If a person walks a straight path, for him there is no cross. However, when he starts to lurch from one side to the other, then different circumstances appear which push him back onto the right track. These elements constitute a cross for a person. Of course they occur differently, according to the individual’s need.' 'Sometimes The cross is a mental one, confusing the individual with sinful thoughts. But the person is not at fault if he doesn’t accede to them. The Starets cited an example: ‘ Once a female ascetic was agitated for a long period over having unchaste thoughts. When Christ appeared and drove them away from her, she cried out to Him: ‘Sweet Jesus, where were You up to this time?’ Christ replied: ‘I was in your heart.’ She said: ‘How can that be? But my heart was filled with unchaste thoughts.’ And Christ said to her: ‘Therefore understand that I was in your heart, and that you had no disposition toward those unclean thoughts but more so, endeavored to liberate yourself from them. Not being able to do so, you suffered over them, thereby preparing a place for me in your heart.’ 'Sometimes, suffering is sent to an innocent person, so that he, as with the example of Christ, suffers for others. Christ Himself suffered for people. Likewise, His Apostles were tortured for the Church and people. To have absolute love means to suffer for your close ones.'
According to the teaching of the Fathers, any impression which, touching the heart, fills it with a great irritation, must come from the region of passions. Therefore impulses which spring from the heart should not be followed at once, but only after careful examination and fervent prayer. God preserve us from a blind heart! It is well known that passions do blind the heart and screen the shining sun of the mind that we should all strive to gaze at.
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.
Pray that you may be granted the grace to read the Fathers with the right understanding, the grace to live up to the standards they put before you, and the grace clearly to see your own frailty. You will not long be left wanting and waiting. God will give you help.
Your past and present torments and sufferings are poured down upon you to test your faith and 'steel' it; they also work to curb your lusts and passions. Humble yourself. God gives help to the humble. Judgment of others, insistence on their shortcomings, can only increase the bitterness of your sorrow. Choose the better part.
Every Christian is obligated according to his strength and station to labor for the good of others, but with the condition that it all be timely and orderly, and that the success of our labors represents God and His holy will.
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.
You ask for some way of completely eradicating irritability. The inclination to irritability is given us to use against sin, and we were never meant to use it against our fellow men. When we do, we act contrary to our true nature.
Bear this in mind: the Christian life is an unending spiritual fight. The wily enemy cleverly uses snares and arrows without number. Before some of us he spreads the lure of worldliness, the outer pride of pomp and circumstance, the cruder lusts-the lusts of the flesh. But those of us who are not attracted by any of this he leads up on to the peaks of subtler prides. Having got us there-to the high country of self-esteem-he causes a dark mist, the mist of the subtlest prides, to enshroud our intellect. Then he leads us, his blinded slaves, away from God, without our even suspecting it. Mark this too: it is not very hard for the simple sinner to come to hate his foul life and, leaving it, to fling himself on the mercy of God; but it is very hard for the subtler sinner-the self-sufficient one-to let a ray of divine love pierce the leather jacket of his self-righteousness... Humility is the only weapon that wards off all attacks, but it is difficult to fashion, and the art of using it is often misunderstood, particularly by those who lead an active, worldly life.
A man cannot correct himself all of a sudden, but it is like pulling a barge - pull, pull, and let go, let go! Not all at once, but little by little. Do you know the mast on a ship? There is a pole to which is tied all of the ship’s lines. If you pull on it then everything gradually pulls. But if you take it all at once, you will ruin everything.
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.
