Trials are sent to some so as to take away past sins, to others so as to eradicate sins now being committed, and to yet others so as to forestall sins which may be committed in the future. These are distinct from the trials that arise in order to test men in the way Job was tested.
You have the book of discourses by St. Macarius of Egypt. Kindly read the 19th discourse, concerning a Christian's duty to force himself to do good. There it is written, 'One must force oneself to pray, even if one has no spiritual prayer.' And, 'In such a case, God, seeing that a man earnestly is striving, pushing himself against the will of his heart (that is, his thoughts), He grants him true prayer.' By true prayer, St. Macarius means the undistracted, collected, deep prayer that occurs when the mind stands unswervingly before God. As the mind begins to stand firmly before God, it discovers such sweetness, that it wishes to remain in true prayer forever, desiring nothing more.
From this minute of his new life, the repentant sinner commences his podvig, struggle, and labor, and begins to bear the burden, the yoke. This is so essential that all the saints accept the only true path to virtue to be pain and hard work. On the contrary, lightness and ease are a sign of a false path, for the kingdom of God suffereth violence, and the violent take it by force (Matt. 11:12). Anyone who is not struggling, not in podvig, is in prelest.
There is one method which, if practiced with full attention, will seldom allow anything passionate to slip unnoticed into the heart. This is to examine our thoughts and feelings, so as to discover which they tend: towards pleasing God or towards pleasing ourselves.
There is nothing more burdensome and grievous then when conscience accuses us in anything, and there is nothing dearer then calmness and approval of the conscience.
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.
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.
The day will come when you are toiling at self-observation and self-constraint, and the adversary will come up and mumble in your ear, 'This will all happen eventually. You’ve been working hard, now take it easy a little bit!' This is such a tempting suggestion that it does not immediately occur to you that you should counter it, or that it is so bad that however little you give in to it, it will cause such inner disturbance. Indulging yourself is just like a tiny hole in a dam. Once a hole has formed, the dam cannot hold; the water will inevitably destroy it. Indulgence does the same thing inside of us; everything will be dispersed, so it will be necessary to start all over again to restore ourselves. Fear this as your most evil enemy, although he speaks with the sweetest words.
Do not measure yourself by the standard of weaker men, but strive rather to apply yourself to the commandment of love. In measuring yourself by the former you fall into the pit of presumption, in striving for the latter you advance to the heights of humility.
The spirit of faith and piety of the parents should be regarded as the most powerful means for the preservation, upbringing and strengthening of the life of grace in children.
Love and self-control free the soul from passions; spiritual reading and contemplation deliver the intellect from ignorance; and the state of prayer brings it into the presence of God Himself.
He who busies himself with the sins of others, or judges his brother on suspicion, has not yet even begun to repent or to examine himself so as to discover his own sins...
He who is not indifferent to fame and pleasure, as well as to love of riches that exists because of them and increases them, cannot cut off occasions for anger. And he who does not cut these off cannot attain perfect love.
In preparing for battle, however, do not think that you will always be victorious. Often there will be only hardship that will bring nothing but affliction... Provide yourself with only one thing, strong courage: no matter what happens, stay with what you have begun... No matter how life goes, whatever successes and failures there are, you should give all of this over to God's will.
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.
Confirm yourself in this truth: that every Divine writing that is in agreement with the path of salvation instructs, teaches, chastises, and strengthens, that our path might be ever according to God.
