What toil we must endure, what fatigue, while we are attempting to climb hills and the summits of mountains! What, that we may ascend to heaven! If you consider the promised reward, what you endure is less. Immortality is given to the one who perseveres; everlasting life is offered; the Lord promises His Kingdom.
If the Lord delays granting you full victory over your enemies and puts it off to the last day of your life, you must know that He does this for your own good; so long as you do not retreat or cease to struggle wholeheartedly. Even if you are wounded in battle, do not lay down your arms and turn to flight. Keep only one thing in your mind and intention - to fight with all courage and ardor, since it is unavoidable. No man can escape this warfare, either in life or in death. And he who does not fight to overcome his passions and his enemies will inevitably be taken prisoner, either here or yonder, and delivered to death.
If someone is judged worthy to receive the gift of knowledge but allows his heart to be full of bitterness or rancor or aversion to another, it is as if he had been struck in the eye by a thornbush. That is why knowledge is no good without charity.
Do not be deluded by thoughts that virtue exceeds your powers and is impossible for you; but, inspired by faith, boldly make a beginning, show before God your good will and diligence - and you will see the help He will send you to practice virtue.
We must with unflagging zeal and care give ourselves to the pursuit of virtue, and constantly occupy ourselves in its practice, lest at any time progress may cease, and regress immediately take its place.... To cease to acquire means to lose, for the will which goes no longer forward will not be far from peril of falling back.
Do not neglect the practice of the virtues; if you do, your spiritual knowledge will decrease, and when famine occurs you will go down into Egypt (Genesis 41:57, 46:6).
Do all in your power not to fall, for the strong athlete should not fall. But if you do fall, get up again at once and continue the contest. Even if you fall a thousand times because of the withdrawal of God's grace, rise up again each time, and keep on doing this until the day of your death. For it is written, 'If a righteous man falls down seven times' - that is, repeatedly throughout his life - 'seven times shall he rise again' [Prov. 24:16].
No matter what misfortune might befall you, no matter what unpleasantness might occur, say 'I will endure this for Jesus Christ's sake!' Just say that, and you will feel better, for the Name of Jesus Christ is powerful. Before It, all difficulties abate, and demons disappear. Your annoyance and faintness of heart will abate when you repeat His most sweet Name. Lord, grant unto me to see my transgressions. Lord, grant unto me patience, magnanimity, and meekness.
If we were willing to make even small efforts, we would not suffer either distress or difficulty. For if a man urges himself to make efforts, then, as he continues them, he gradually makes progress and later practices virtues with tranquility; for God, seeing him urge himself, sends him help. So let us urge ourselves, for, although we have not reached perfection, if we make efforts, through efforts we shall receive help, and with this help shall acquire all kinds of virtues. Therefore one of the fathers said, 'Give blood and receive spirit,' that is, strive and you will become practiced in virtue.
A Christian has great difficulty in attaining three things: grief (over sins), tears, and the continual memory of death. Yet these contain all of the other virtues.
The abstinent withdraws from gluttony, the uncovetous from covetousness, the silent from wordiness, the pure from attachment to sensory pleasures, the chaste from fornication, he who is content with what he has from love of money, the meek from agitation (anger), the humble from vanity, the obedient from objection, he who is honest with himself from hypocrisy; equally, he who prays withdraws from despair, the willing pauper from acquisitiveness, he who professes his faith from denying it, the martyr from idolatry – so you see that each virtue, performed even unto death, is nothing but withdrawal from sin; and withdrawal from sin is a natural action, not an action which could be rewarded by the kingdom.
