Our holy fathers have renounced all other spiritual work and concentrated wholly on this one doing, that is, on guarding the heart, convinced that, through this practice, they would easily attain every other virtue, whereas without it not a single virtue can be firmly established.
If you examine your life well, you will find many instances when God showed His unmistakable mercy to you. Trouble was brewing, but it passed you by for some reason. God delivered you. Acknowledge these and thank God, Who loves you.
Wherefore, do not remember your good deeds, in order that God may remember them. Do thou first confess thy sins, it is written, that thou mayest be justified (Isaiah 43:26).
Great is this mystery, and great is the mercy of God towards man. If all the people of the earth knew how deeply the Lord loves man their hearts would be filled with love of Christ and Christ’s humility, and they would seek to be like Him in all things. But man cannot do this by himself, for it is only in the Holy Spirit that he can become like unto Christ. Man that is fallen purifies himself through repentance, and is made new by the grace of the Holy Spirit, and in all things becomes like unto the Lord.
Men who are leading a spiritual life see by the eyes of their heart how the devil lays his snares, how the angels guide us, and how the Lord, in His Sovereign power, allows the temptations, and how he comforts.
For, just as it is good to recall one's sins, so it is also good to forget one's good deeds. Why is this? Because remembrance of our good deeds puffs us up with arrogance, whereas remembrance of our sins curbs and humbles our mind; the former makes us more sluggish, but the latter makes us more diligent. Indeed, those who do not think that they have anything good become more eager to acquire what is good, whereas those who reckon that they have stored up a great deal of merchandise, confident they have an abundance of this, do not display much zeal for obtaining more of it.
The Holy Fathers teach us how to become familiar with the Gospel, how to read it and how to understand it, what helps and what opposes its understanding. Therefore, at first you must devote more time to reading the Holy Fathers. When you have learned from them how to read the Gospels, then give your preference to them.
Even if we have thousands of acts of great virtue to our credit, our confidence in being heard must be based on God's mercy and His love for men. Even if we stand at the very summit of virtue, it is by mercy that we shall be saved.
Every day you provide your bodies with good to keep them from failing. In the same way your good works should be the daily nourishment of your hearts. Your bodies are fed with food and your spirits with good works. You aren't to deny your soul, which is going to live forever, what you grant to your body, which is going to die.
