Remember that a good action is always either preceded or followed by temptations. God permits this so that the virtue, exercised in that particular action, may be confirmed, consolidated, steeled.
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.
The lives of men are subject to drastic changes. These changes are gradual at times; at others, lightning quick. But even those of us who enjoy long years of opulence and fame can find no consolation, no gladness, unless our heart is illumined by the steady light of peace. It is this peace that we must seek, it is for this peace that we should pray. The peace that our Lord gave to His disciples and to all those who really have faith in him.
With pain and tears you will receive grace, and again with tears and joy and thanksgiving, with fear of God you will keep it. With zeal it is drawn. With coldness and negligence it is lost.
An old man was asked, 'How can I find God?' He said, 'In fasting, in watching, in labors, in devotion, and, above all, in discernment. I tell you, many have injured their bodies without discernment and have gone away from us having achieved nothing. Our mouths smell bad through fasting, we know the Scriptures by heart, we recite all the Psalms of David, but we have not that which God seeks: charity and humility.'
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.
Having withdrawn from the palace to the solitary life, Abba Arsenius prayed and heard a voice saying to him, 'Arsenius, flee, be silent, pray always, for these are the source of sinlessness.'
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.
A certain brother asked the Abbot Poemen, saying, 'What am I to do, Father, for I am troubled in sadness?' The old man said to him, 'Look to no man for aught, condemn no man, disparage no man: and God shall give thee rest.'
One of the fathers used to say that some old men were sitting one day and talking of what was useful to the soul. One of them had the gift of vision, and he saw angels who were waving branches in honor of the old men, but when one of them began to speak of irrelevant things the angels withdrew, and some pigs walked amongst the old men bringing a bad smell and messing up everything. As soon as they began once again to speak of what was useful to the soul, the angels returned to do them honor.
You describe how bitterly you regret the inefficacy of your prayers. Beware: to wish for consolation or revelation in prayer is a sure sign of pride. Pray humbly, in perfect simplicity, seeking salvation only through forgiveness, & having faith that God will extend to you His mercy - as He did to the publican.
Have great care of your children. We live at a time when much freedom is given to the expression of thought, but little care is taken that thoughts should be founded on truth. Teach them to love truth.
