Till the advent of grace man lives his life and thinks that all is well and prosperous with his soul; but when grace visits him and dwells with him he sees himself quite otherwise, and losing grace again he realizes his unhappy state.
I beseech you, put this to the test. When a man affronts you or brings dishonor on your head, or takes what is yours, or persecutes the Church, pray to the Lord, saying: 'O Lord, we are all Thy creatures. Have pity on Thy servants and turn their hearts to repentance,' and you will be aware of grace in your soul. To begin with, constrain your heart to love enemies, and the Lord, seeing your good will, will help you in all things, and experience itself will show you the way. But the man who thinks with malice of his enemies has not God's love within him, and does not know God.
The Lord does not reveal Himself to many because of their intellectual pride; yet they think that they have much knowledge. But what is their knowledge worth, if they know not the Lord, know not the grace of the Holy Spirit, know not how this grace comes and wherefore it is lost? But let us humble ourselves, brethren, and the Lord will show us all things, as a loving father shows all things to his children.
Blessed are the pure in heart, for they shall see God. Everything we do, our every objective, must be undertaken for the sake of this purity of heart. This is why we take on loneliness, fasting, vigils, work, nakedness. For this we must practice the reading of the Scripture, together with all the other virtuous activities, and we do so to trap and to hold our hearts free of the harm of every dangerous passion and in order to rise step by step to the high point of love.
Train yourself to cut off an intrusive thought immediately… Be at pains over this, so that you acquire the habit. The soul is a creature of habit: according to the habit you have acquired, so will you act all the rest of your life.
Temptations are sent for improvement when God delivers his righteous ones to various temptations, humiliating them for some slight and unimportant offense, or to increase their purity, in order that every uncleanliness of thought, or... dross which He sees they have harbored in secret, may be burnt away in this present life, and that so He may bring them, as it were pure gold, to the future judgment...
He is not yet a faithful servant who bases himself on bare knowledge alone; a faithful servant is he who professes his faith by obedience to Christ, Who gave the commandments.
The fear of the Lord is the beginning of our salvation, and its constant guardian. This it is which secures both the beginning of conversion, and the purging away of vices, and the safe retention of virtues...
Our enemies (demons) fell because of their pride, and call us to follow them, and bring us feelings of praise. And if your soul accepts that praise, then grace will depart, until the soul becomes humble again. And so all your life you must learn the humility of Christ.
The more wood you pile on a fire the more heat you get, and thus it is with God - the more you think on Him the more you are fired with love and fervor towards Him. He who loves the Lord is always mindful of Him, and remembrance of God begets prayer.
If we remember the thief who, for a single confession on the cross, was taken into Paradise, we shall realize that it was not for the merit of the life he lived that he obtained so great blessedness, but that it was his by the gift of God, Who had mercy on him. Or, let us think of David, the king, whose two grievous and awful crimes were wiped away by one word of penitence. Neither here do we see that the merit of what he did was equal to obtaining pardon for such great offense, but the grace of God did the more abound when on the occasion of true penitence He did away with all that weight of sin for one single word of genuine confession. Again, when we consider the beginnings of man's calling and salvation, which, as the Apostle tells us, is not of ourselves or of our words, but we are saved by the gift and grace of God, we shall be able clearly to perceive how the end of perfection is not 'of him that willeth, nor of him that runneth, but of God Who showeth mercy,' Who makes us victors over our vices, although we have no merit at all of life or labors to weigh against them, nor does the effort of our will avail for us to reach the steep summit of righteousness, or to subdue the flesh which we are bound to use... For the outcome of all good flows from His grace, Who hath bestowed so great an eternity of bliss and such immeasurable glory, with manifold generosity, upon the weak will and the short life-work of man.
