Both public and private prayer are necessary in order that we may lead a truly Christian life, and that the life of the spirit should not become extinct in us. It is indispensable that we should attend divine service in church with faith, zeal and understanding, just as it is indispensable to provide a lamp with fuel or power if it is to burn and not to go out.
Sometimes younger people, or those of equal station, or older ones, teach you by means of hints which you cannot endure, and you are vexed with your teachers. We must endure and listen with love to everything useful coming from anyone, whoever he may be. Our self-love conceals our faults from us, but they are more visible to others. This is why they remark them to us. Remember, that 'we are members one of another,' and are thus obliged to mutually correct each other. If you do not bear being instructed by others, and are vexed with those who teach you, it means that you are proud, and this shows that the fault of which others hint that you should correct yourself is really in you.
If you wish that God should speedily give you hearty faith in prayer, strive with all your heart to speak and to do everything in regard to other people sincerely, and never be deceitful in your dealings with them. If you are straightforward and truthful with others, then God will give you straightforwardness and sincere faith also in reference to Himself.
What does the daily invocation of the saints signify - of different ones each day, during the whole year, and during our whole life? It signifies that God's saints, as our brethren - but perfect - live, and are near us, ever ready to help us, by the grace of God. We live together with them in the house of our Heavenly Father, only in different parts of it. We live in the earthly, they in the heavenly half, but we can converse with them, and they with us. God's saints are near to the believing heart, and are ready in a moment to help those who call upon them with faith and love
Truth is the foundation of everything that has been created. Let truth be also the foundation of all your works (both inward and outward), and especially the foundation of your prayers. Let all your life, all your works, all your thoughts, and all your desires be founded upon truth.
Your enemy, the evil one, the father of lies, does not slumber; and endeavors, by every means open to him, to harden your heart --- to make it false and crafty, to drive out from it faith and hope in God - together with love for Him and love and sympathy for your neighbor - and to occupy you with worldly, temporal interests. Watch yourself, watch the thoughts of your heart, and do not bind yourself in the chains of worldly desires and pleasures. Let your happiness be in the one God and the human soul.
You see how bright the sun and the stars are. 'Then shall the righteous shine forth as the sun' from the inner immaterial light of God. Whenever the angels appear upon earth, they are almost always surrounded by light. Aspire to that enlightenment. Throw aside the works of darkness. We can raise our nature to communion with the Divine Nature; and God is the Light uncreated, surpassing every light that has been created.
In the Church we are freed from worldly enchantment, and from the intoxication of worldly passions and desires; we become enlightened, sanctified, cleansed in our souls; we draw near to God, we are united with God ('Who, by Thy glorious Childbirth, hath united God the Word with men') How worthily reverenced and loved should the temple of God be! How God’s Saints loved it!
The evil spirit tries to scatter prayer as if it were a sand heap, tries to turn the words into dry sand, without coherency or moisture - that is to say, without fervor of heart. Thus prayer may become either a house built on sand or a house built on a rock. Those build on sand who pray without faith, absently, coldly: such prayer is scattered of itself, and does not bring any profit to him who prays; those build on a rock who, during the whole time of their prayer, have their eyes fixed upon God, and pray to Him as to a living person, conversing face to face with them.
Often during the day I have been a great sinner, and at night, after prayer, I have gone to rest, justified and whiter than snow by the grace of the Holy Ghost, with the deepest peace and joy in my heart! How easy it will be for the Lord to save us too in the evening of our life, at the decline of our days! O! save, save, save me, most gracious Lord; receive me in Thy heavenly Kingdom! Everything is possible to Thee.
Pray before your body takes rest on your bed... If you are tempted, make the Sign (of the Cross) on your forehead reverently… for this is a known and tested weapon against the Devil.
If some Christians cannot comprehend our Orthodox faith, its Sacraments, it proves that the minds and hearts of such persons are too impure and passionate to bear its purity and brightness, just as sick eyes cannot bear the light of the sun. This heavenly treasure can only be comprehended by the hearts of those who free their minds and feelings from worldly attachments.
Those who attend the divine service of the Orthodox Church must bear in mind that its purpose is to prepare us for the joyful service of God in heaven; that in serving God with the body, it is still more necessary to serve God with the soul and a pure heart; that in hearing divine service they must learn to serve God as those saints served him, whose lives, and works of faith, hope and love, we hear of during the service; that God should, above all, be served in deed and truth, and not only by words and the tongue.
When praying, endeavor by every means to feel in your heart the truth and the power of the words of the prayer; feed yourself upon them as upon an imperishable food; water your heart with them as with a dew; and warm yourself by them as by means of a beneficial fire.
St. John Climacus was asked if there are reliable signs by which it's possible to know whether a soul is drawing near to God or moving away from Him. After all, regarding ordinary things there are clear signs as to whether they're good or not. When, for instance, cabbage, meat or fish begins to rot, it's easy to notice it, since the rotting object begins to give off a foul odor, the color and taste change, and its external appearance witnesses to its deterioration. Well, and what about the soul? After all, it's bodiless and can't give off a bad smell or change its appearance. To this question the Holy Father replies, 'A sure sign of the deadening of the soul is the avoidance of church services.'
