If a man only theorises about God, then he is helpless, utterly helpless, when confronted by an evil spirit. An evil spirit laughs at feeble worldly theorising. But as soon as a man begins to fast and to pray to God, the evil spirit becomes filled with inexpressible fear.
The fear of God is the beginning of virtue, and it is said to be the offspring of faith. It is sown in the heart when a man withdraws his mind from the world’s distraction so as to confine its wandering thoughts within the ruminations of reflection upon the restitution to come.
He who knows not the Son cannot know the Father. He who knows the Son knows the Father also. He who sees the Son sees the Father also. God cannot be known without His light, which came among men. The light of the Father is the Son. 'I am the light', said Christ. And the light shines in darkness. The physical world would be in total darkness if it were not for the light of the sun, and the spiritual and moral world, and all human life, would be in darkness if it were not for the light that is from the Father. And that light is Christ the Lord.
As a man whose head is under water cannot inhale pure air, so a man whose thoughts are plunged into the cares of this world cannot absorb the sensations of that new world.
The key to Divine gifts is given to the heart by love of neighbor, and, in proportion to the heart's freedom from the bonds of the flesh, the door of knowledge begins to open before it.
'When ye suffer for righteousness’ sake, blessed are ye, seeing that ye are become partakers of the sufferings of Christ' (1 Peter 3:14; 4:13). Therefore, when you are unoppressed do not rejoice; and when tribulations come upon you, do not be sullen, accounting them as foreign to God’s way. For His path has been trodden from the ages and from all generations by the cross and by death. But how is it with you, that the afflictions on the path seem to you to be off the path? Do you not wish to follow the steps of the saints? Or have you plans for devising some way of your own, and of journeying therein without suffering?
He who believes in Christ is not judged, for he judges himself, and sets his feet aright to follow the light that goes before him. As a man in deep darkness adapts his step to the candle in his hand, so also he who believes in Christ; that is, he who is set to follow after Christ as the light in the darkness of life.
Prayer offered up at night possesses a great power, more so than the prayer of the day-time. Therefore all the righteous prayed during the night, while combating the heaviness of the body and the sweetness of sleep and repelling bodily nature.
Courage does not consist in defeating and oppressing one's neighbor, for this is overbearingness, which oversteps the bounds of courage. Nor again does it consist in fleeing terrified from the trials that come as a result of practicing the virtues; for this is cowardice and falls short of courage. Courage itself consists in persisting in every good work and in overcoming the passions of soul and body. For our struggle is not against flesh and blood, that is, against men, as was the case with the Jews of old, where to conquer other nations was to do the work of God; it is against principalities and powers, that is, against the unseen demons (Ephesians 6:12). He who is victorious conquers spiritually; otherwise he is conquered by the passions. The warfare described in the Old Testament prefigures our spiritual warfare. These two passions of overbearingness and cowardice, though they appear to be opposites, are both caused by weakness. Overbearingness pulls one upwards and is outwardly something startling and frightening, like some powerless bear, while cowardice flees like a chased dog. No one who suffers from either of these two passions puts his trust in the Lord, and therefore he cannot stand firm in battle, whether he is overbearing or cowardly. But the righteous man is as bold as a lion (Proverbs 28:1) in Christ Jesus our Lord, to whom be glory and dominion throughout the ages.
Whenever in your path you find unchanging peace, beware: you are very far from the divine paths trodden by the weary feet of the saints. For as long as you are journeying in the way to the city of the Kingdom and are drawing near the city of God, this will be a sign for you: the strength of the temptations that you encounter. And the nearer you draw close and progress, the more temptations will multiply against you.
