Christians should judge no one, neither an open harlot, nor sinners, nor dissolute people, but should look upon all with simplicity of soul and a pure eye. Purity of heart, indeed, consists in seeing sinful and weak men and having compassion for them and being merciful.
He is not yet a faithful servant who bases himself on bare knowledge alone; a faithful servant is he who professes his faith by obedience to Christ, Who gave the commandments.
If you wish to be saved and 'to come unto the knowledge of the truth' (I Tim. 2:4), endeavor always to transcend sensible things, and through hope alone to cleave to God. Then you will find principalities and powers fighting against you (Eph. 6:12), deflecting you against your will and provoking you to sin. But if you prevail over them through prayer and maintain your hope, you will receive God's grace, and this will deliver you...
The head of every good striving and the pinnacle of all corrections is to persevere in prayer, by which we may ever obtain, through entreaty of God, all the other virtues as well. By prayer those who are worthy partake of the sanctity of God and spiritual activity and the union of the mind with the Lord in unutterable love. He who constantly forces himself to endure in prayer is roused by spiritual love to Divine fervor and flaming desire towards God, and he receives, according to his measure, the grace of spiritual, sanctifying perfection.
This is the mark of Christianity--however much a man toils, and however many righteousnesses he performs, to feel that he has done nothing, and in fasting to say, 'This is not fasting,' and in praying, 'This is not prayer,' and in perseverance at prayer, 'I have shown no perseverance; I am only just beginning to practice and to take pains;' and even if he is righteous before God, he should say, 'I am not righteous, not I; I do not take pains, but only make a beginning every day.'
What can God do with one who willfully gives himself over to the world, and is deceived by its pleasures, or led astray by material wanderings? The man to whom He gives help is the one who turns away from material pleasures and from his former habits, who drags his mind at all times to the Lord, whether it will or not, who denies himself and seeks the Lord only. This is the man whom He keeps under His care: who guards himself on every side from the snares and entanglements of the material world, who works out his own salvation with fear and trembling, who passes with all heed amidst the snares and entanglements and lusts of this world, and seeks the help of the Lord, and hopes by His mercy to be saved through grace.
Wherefore a man can know nothing about the judgments of God. He alone is the One Who takes account of all and is able to judge the hearts of each one of us, as He alone is our Master. Truly it happens that a man may do a certain thing (which seems to be wrong) out of simplicity, and there may be something about it which makes more amends to God than your whole life; how are you going to sit in judgment and constrict your own soul? And should it happen that he has fallen away, how do you know how much and how well he fought, how much blood he sweated before he did it? Perhaps so little fault can be found in him that God can look on his action as if it were just, for God looks on his labor and all the struggle he had before he did it, and has pity on him. And you know this, and what God has spared him for, are you going to condemn him for, and ruin your own soul? And how do you know what tears he has shed about it before God? You may well know about the sin, but you do not know about the repentance.
In truth, whatever we may suffer, we suffer it because of our sins. If the saints suffered, they suffered for God's name or to demonstrate their virtue for the benefit of many or to gain greater reward from God. As for us wretches, how can we say this? We sin like this daily and in seeking to satisfy our passion, we abandoned the right path, which the Fathers spoke about, that of self-accusation. Each one of us follows the wrong path, tries on every occasion to put the case against his brother and throw the burden of responsibility upon him. Each one of us is negligent and keeps nothing, but demands that our neighbor keeps the commandments.
Also in another place it shows that the angels are the ministers of the saints. For when Elijah was on the mountain and foreigners were rising up against him, his servant said, 'Many are coming against us and we are all alone.' Then Elijah answered, 'Do you not see the armies and multitudes of angels with us surrounding us to aid us?' (2 Kg. 6:15). You see how the Master and the multitude of angels are standing by the side of their servants.
