The roof of any house stands upon the foundations and the rest of the structure. The foundations themselves are laid in order to carry the roof. This is both useful and necessary, for the roof cannot stand without the foundations and the foundations are absolutely useless without the roof-- no help to any living creature. In the same way the grace of God is preserved by the practice of the commandments, and the observance of these commandments is laid down like foundations through the gift of God. The grace of the Spirit cannot remain with us without the practice of the commandments, but the practice of the commandments is of no help or advantage to us without the grace of God.
The man of Christ embarks upon the path of divine perfection by overcoming, with the aid of evangelical virtues, the sin and evil within him and in the world around him. He constantly marches on from one good to another, from smaller to greater, from greater to greatest. In this progress he never pauses, for any delay would bring spiritual stagnation, numbness, death. Through every pure thought, every holy sentiment, every good desire and kindly word, he progresses toward resurrection, immortality, eternal life.
Therefore, let us force ourselves. Let us make a beginning and let us desire the good with all our heart. Because, even if we are not perfect, wanting to be, is the beginning of our salvation. From wanting we come, with God’s help, to struggling and from struggling one is helped in acquiring the virtues. This is why one of the fathers says, 'Give blood and receive spirit', that is to say, 'Struggle and you will become accustomed to virtue.'
My brother, the passions are afflictions; and so the Lord does not excommunicate us because of them, but He says: 'Call upon me in the time of affliction; and I will deliver thee, and thou shalt glorify me'. Therefore, when beset by any kind of passion, there is nothing more useful than to call upon the Name of God. All we can do, weak as we are, is to flee for refuge to the Name of Jesus. For the passions, being demons, retreat if this Name is invoked.
It is not always possible to fulfill the usual rules; one must take circumstances into account and try to fulfill what they make possible, as far as one can. The demons themselves are not unmindful of this law. So, being in constant enmity with us, they prevent us from doing what is possible and urge us to do what is impossible.
Almsgiving heals the soul's incensive power; fasting withers sensual desire; prayer purifies the intellect and prepares it for contemplation of created beings. For the Lord has given us commandments which correspond to the powers of the soul.
