From My Life in Christ
When you walk in a forest, garden, or meadow, and see the young shoots of the plants, the fruits on the trees, and the variety of the flowers of the field, learn a lesson from God’s plants--namely, the lesson that every tree each summer unfailingly puts forth at least one shoot of considerable size, and unfailingly grows in height and dimensions. It seems as though every tree endeavors each year to advance by the strength that God has given it; therefore, say to yourself, I, too, must each day, each year, absolutely grow higher and higher morally, better and better, more and more perfect; must advance on the road to the Kingdom of Heaven, or to the Father which is in Heaven, through the strength of our Lord Jesus Christ and His Spirit dwelling and working within me. As the field is adorned by a multitude of flowers, so should the field of my own soul be adorned by all the flowers of virtue; as the trees bring forth flowers and afterwards fruit, so must my soul bring forth the fruits of faith and good works.

What is prayer? What is its essence? How can we learn to pray? What does the spirit of the Christian experiences as he prayers in humility in his heart?
All such questions should constantly occupy the mind and heart of the believer, for in prayer man converses with God, he enters, through grace, into communion with Him, and lives in God. And the Holy Father and teachers of the Church gives answers to all these questions, based on the grace-given enlightenment which is acquired through the experience of practicing prayer – experience equally accessible to the simple and to the wise.
Prayer is the test of everything; prayer is also the source of everything; prayer is the drive force of everything; prayer is also the director of everything. If prayer is right, everything is right. For prayer will not allow anything to go wrong.
from My Life in Christ
by St. John of Kronstadt
If you wish to ask of God in prayer any blessing for yourself, then before praying prepare yourself for undoubting and firm faith, and take in good time means against doubt and unbelief. For it will go ill with you if during the prayer itself your heart wavers in its faith and does not stand firm in it; then do not even expect to obtain of the Lord what you have prayed for doubtingly, for in so doing you have offended the Lord, and God does not bestow His gifts upon a reviler. "And all things, whatsoever ye shall ask in prayer, believing, ye shall receive,"  said the Lord. This means, that if you doubt and do not believe, you shall not receive. "If ye have faith and doubt not," said He also, "ye shall have power to move mountains." 
Therefore, if you doubt and do not believe, you shall not have power to do so. "Let him ask in faith, nothing wavering, for he that wavereth is like a wave of the sea driven with the wind and tossed," says the Apostle James; "for let not that man think he shall receive anything of the Lord. A double-minded man is unstable in all his ways." 
Prayer makes up a significant part in every major religious tradition. Thus, if a cross-section of Chaplain Corner readers were asked, “What is prayer,” a variety of definitions would likely emerge. Many would possibly resemble the one I remember from my childhood catechism: “Prayer is the lifting of our minds and hearts to God.” Prayer can be active or passive, individual or communal. Many of the different forms of prayer may contain aspects of worship, petition and thanksgiving. Our Eastern Church Spiritual Father St. Mark the Ascetic tells us: "There are many different methods of prayer. . . . No method is harmful. . . .” (Philokalia I). St. Dorotheos of Gaza (Wheeler, 1977) reflects the common teaching of the Eastern Fathers that for prayer to be effective it has to be done with a pure heart.

The Holy Fathers of the Church have determined that there are three indispensable means of participating in Great Lent. They are fasting, spiritual vigilance and prayer. These disciplines derive from God's word and have through the centuries been the mainstay of Eastern Orthodox spirituality or life in Christ.
When Jesus had fasted forty days and forty nights in the wilderness in preparation for His saving ministry, we are told that the devil tempted Him to change stones into loaves of bread. The Lord rebuked the tempter with the words, "It is written, 'Man shall not live by bread alone, but by every word that proceeds from the mouth of God'"(Matthew 4:14; Deuteronomy 8:3). In this way Jesus succeeded where Adam had failed (Genesis 3:1-6). His answer to Satan is a trenchant affirmation that to live our lives as though God did not exist, that is, "by bread alone," is to live according to a demonic lie.
The Lord's words and steadfast self-denial alert us to the particular lifestyle He expects of His followers, expressed elsewhere: "Enter by the narrow gate; for the gate is wide and the way is easy, that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard, that leads to life, and those who find it are few" (Matthew 7:13-14).

The world in which we live is an anxious one, rife with fear and doubt. Economic markets rise and fall, employment fluctuates, conflicts erupt in unexpected places, and each year seems to bring a threat of some new virus that threatens mankind.
“Let the favor of the Lord our God be upon us, and establish thou the work of our hands upon us, yea, the work of our hands establish thou it.” (Ps 89: 17)
Many Eastern Church Christians starts the day with morning prayer reading Psalm 89 which asks God to bless our work. St. Paul tells us: “For we are God's fellow workers; you are God's field, God's building.” (1 Cor 3:9).
The Godliness of work is not unique to the Eastern Christian Church. Many religious traditions also ask God to bless the work that is done by man. Mahatma Gandhi said, “It is the quality of our work which will please God and not the quantity.”[i] He also tell us: “Infinite striving to be the best is man's duty, it is its own reward. Everything else is in God's hands.”[ii] In the Islamic tradition, the Koran states: “And say: Work; so Allah will see your work and (so will) His Apostle and the believers; and you shall be brought back to the Knower of the unseen and the seen, then He will inform you of what you did.”[iii]
