There are three things that move us to the good: natural tendencies, the holy Powers, good choice. The natural tendencies - as, for instance, when what we wish men would do for us, we likewise do for them; or, when we see someone in sore straits, we then naturally have pity. The holy Powers - as when moved to some fine deed, we experience their good assistance and prosper. Good choice - when, for example, discerning good from evil, we choose the good.
In order, then, that Christ may win us all unto obedience, He promises us surpassing honors, and deigns us the highest love, saving, `My mother and My brethren are those who hear the word of God and do it.' For who among men is so obdurate and ungentle, as to refuse to honor, and accord the most complete love to his mother and brethren? For the all-powerful law of nature, even without our will, obliges us to this. When, therefore, bowing our neck to the Savior's commands, we become His followers, and so are in the relation of a mother and brethren to Him, how does He regard us before God's judgment seat? Is it not with gentleness and love? What doubt can there be of this?: And what is comparable to this honor and goodness? What is there worthy of being matched with a gift thus splendid and desirable?
Do not befoul your intellect by clinging to thoughts filled with anger and sensual desire. Otherwise you will lose your capacity for pure prayer and fall victim to the demon of listlessness.
The one who prays ought never to halt his movement of sublime ascent toward God. For just as we should understand the ascent 'from strength to strength' as the progress in the practice of the virtues, 'from glory to glory' (2 Cor. 3:18) as the advance in the spiritual knowledge of contemplation, and the transfer from the letter of sacred writing to its spirit, so in the same way the one who is settled in the place of prayer should lift his mind from human matters and the attention of the soul to more divine realities.
God smiles on the compassionate heart. Every time a beggar knocks at your door, try to perceive Christ Himself under the humble disguise. Would you, under any circumstances, let Christ knock in vain? The moral qualities of the individual beggar have nothing to do with it; that is Christ's concern, not yours. Who are you to judge your brother? Christ is using the beggar’s hand and mouth to test your compassion of Himself. Will you fail Him?
Unceasing prayer means to have the mind always turned to God with great love, holding alive our hope in Him, having confidence in Him whatever we are doing and whatever happens to us. That is the attitude that the Apostle had when he wrote: ‘Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril? Neither death nor life nor any other creature shall be able to separate us from the love of God in Christ Jesus.’ [cf. Rom. 8:35-38]
When the intellect begins to advance in love for God, the demon of blasphemy starts to tempt it, suggesting thoughts such as no man but only the devil...could invent. He does this out of envy, so that the man of God, in his despair at thinking such thoughts, no longer dares to soar up to God in his accustomed prayer. But the demon does not further his own ends by this means. On the contrary, he makes us more steadfast. For through his attacks and our retaliation we grow more experienced and genuine in our love for God.
Do not lend your ear to the tongue of the slanderer, nor your tongue to the ear of him who likes malicious talk, speaking or listening with enjoyment to words against one's neighbor. Cut yourself off from them, lest you fall away from love of God and find yourself exiled from eternal life.
If the words of God are uttered merely as verbal expressions, and their message is not rooted in the virtuous way of life of those who utter them, they will not be heard. But if they are uttered through the practice of the commandments, their sound has such power that they dissolve the demons and dispose men eagerly to build their hearts into temples of God through making progress in works of righteousness.
It is no small struggle to be freed from self-esteem. Such freedom is to be attained by the inner practice of the virtues and by more frequent prayer; and the sign that you have attained it is that you no longer harbor rancor against anybody who abuses or has abused you.
He who has been granted the grace of spiritual knowledge and yet harbors resentment, rancour or hatred for anybody, is like someone who lacerates his eyes with thorns and thistles. Hence knowledge must be accompanied by love.
Most people desire and seek after prosperity in this life, and they strive to avoid sorrows. While that seems very good and pleasant, constant prosperity and good fortune do a person harm. He falls into a variety of passions and sins, and angers the Lord, while those who live a life of sorrow come closer to the Lord and more readily attain unto salvation, for the Lord called the life of happiness the broad path. The wide gates and the broad way lead to destruction, and many there be who take that way (Matthew 7:13). It is the narrow way and the strait gate which lead to life eternal, and few there be who find it (Matthew 7:14). Thus, according to His love for us, seeing the possible benefit [of sorrows] to those who are worthy, the Lord moves many off the broad road and puts them on the narrow, sorrowful path, so that in [their] patient endurance of sickness and sorrow, He might effect their salvation and grant them life eternal.
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.
When you fail to carry out the divine precepts of faith, your faith is blind. For if the precepts of God are light, it is clear that when you fail to put the divine precepts into practice you are without divine light. You are God's servant merely in name, not in reality.
If in time of trial a man does not patiently endure his affliction, but cuts himself off from the love of his spiritual brethren, he does not yet possess perfect love or a deep knowledge of divine providence.
