Apostolic teaching, Beloved, exhorts us that we put off the old man with his deeds (Eph. iv. 22; Col. iii. 9), and renew ourselves from day to day by a holy manner of life. For if we are the temple of God, and if the Holy Spirit is a Dweller in our souls, as the Apostle says: You are the temple of the living God (II Cor. vi. 16); we must then strive with all vigilance that the dwelling of our heart be not unworthy of so great a Guest.
Fire makes iron impossible to touch, and likewise frequent prayer renders the intellect more forceful in its warfare with the enemy. That is why the demons strive with all their strength to make us slothful in attentiveness to prayer, for they know that prayer is the intellect's invincible weapon against them.
And among all the works of God, before which the mind grows faint with awe, which so rejoices yet overwhelms the soul as the Passion of our Savior? For as often as we dwell, as best we can, upon His Omnipotence, which He shares with the Father in one and the same nature, more wondrous does His lowliness seem to us than His power; and with more difficulty do we grasp His emptying Himself of the divine Majesty, than His sublime uplifting of the form of a servant.
If the base of a felled tree that has grown old in the earth and rock ‘will bud at the scent of water . . . like a young plant’ (Job 14:9), it is also possible for us to be awakened by the power of the Holy Spirit and to flower with the incorruptibility that is ours by nature, bearing fruit like a young plant, even though we have fallen into sin.
When you ae conscious of the sweetness of divine grace working in you and when prayer operates in your heart, then you must continue in it. Do not interrupt it or rise up to sing psalms as long as God sees fit to leave its work in you, for to do so would be to leave God who is within, in order to call on Him outside yourself, as if one were to leave the heights to stoop down to the flats.
In so much as you sincerely compel yourself to do God's commandments, an understanding of the infirmity of your being will be born in you, and in as much as you have this understanding, one of the basic Christian virtues, humility, will in turn be born. God's grace is given only for humility, not for works, although humility is engendered by works. This is the law of true asceticism.
There is nothing more efficacious against the wiles of the devil, dearly beloved, than the kindness of forgiveness, and the bountifulness in charity, by means of which sin is either avoided or overcome.
Nothing that happens to us is contrary to the will of Providence, and everything that is sent us by God is for our good and the salvation of our soul. Even if it does not seem helpful at the moment, we shall understand later on that it was willed so by God, and that it is not what we ourselves wish that is always useful to us. God sends trials out of his Mercy, so that after we have suffered, we may be crowned by Him. Without temptation it is impossible to receive a crown. This is why we should thank God for these sufferings, as out Benefactor and Savior.
Accordingly, a man will neither be puffed up through pride, nor cast down by despair, if he uses the good things divinely bestowed on him, to the glory of the Giver; withholding his desires from the things which he knows will hurt him. And so he that would preserve himself from the wickedness of envy, from the corruption of sensuality, from the unrest of anger, from the desire of revenge, will be purified by the sanctifying power of true abstinence, and will taste the joy of imperishable delights, so that by making spiritual use of them, he will learn to change earthly possessions into heavenly, not by storing what he has received, but by multiplying more and more that which he has been given.
No Christian believing rightly in God should ever be off his guard. He should always be on the look-out for temptation, so that when it comes he will not be surprised or disturbed, but will gladly endure the toil and affliction it causes, and so will understand what he is saying when he chants with the prophet: 'Prove me, O Lord, and try me' (Ps. 26:2 LXX). For the prophet did not say, 'Thy correction has destroyed me,' but, 'it has upheld me to the end' (Ps. 18:35 LXX).
