If Moses, who was a god to Pharaoh, was shut out from the Land of Promise because of one word, how much more will not the evil speech of our tongue, by which we offend and hurt both God and man, shut us out from heaven?
Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
If a righteous man can barely be saved, then where will I end up, I who am lawless and sinful? If the path that leads to life is strait and narrow, then how can I be vouchsafed such good things, I who live a life of luxury, indulging in my own pleasures and dissipation? But Thou, O Lord, my Saviour, Son of the true God, as Thou knowest and desirest it, by Thy grace alone, freely turn me away from the sin that abides in me and save me from ruin.
A blossom is the beginning of fruit bearing and submission the beginning of humility. The humble man is, as a rule, obedient, respects the lowly and the great, and shows leniency and kindness.
Woe is he who knowingly chooses to sin with the intention to repent when morning comes, for he knows not what the coming day or the night that precedes it will bring.
If we use all means and all efforts to avoid death of the body, how much more must we seek to avoid death of the soul. For there is no obstacle for a man wishing to be saved, except negligence and laziness of soul.
Beware of the counsels of the evil one, if he should come in the guise of one professing truth to beguile you and lead you into deceit. Even if he should come to you as an angel of light, do not believe him or obey him: for he is apt to fascinate the faithful by the attractive semblance of truth.
Remember me, ye heirs of God, ye brethren of Christ, supplicate the Saviour earnestly for me, that I may be freed though Christ from him that fights against me day by day.
The good Physician calls me and demands no payment, nor does he spill my blood. But my slothfulness prevents me from going to Him. He comes Himself to heal me, but always finds me engaged in acts that prevent His remedies from rendering me their healing power.
My children, desire to purify your hearts from envy and from anger with each other, lest death should overcome you, and you will be counted among the murderers. For whosoever hates his brother, kills a soul.
