O man, learn the humility of Christ and the Lord will give you to taste of the sweetness of prayer. And if you would pray cleanly, be humble and temperate, confess yourself thoroughly, and prayer will feel at home in you. Be obedient, submit with a good conscience to those in authority; be content with all things, and your mind will be cleansed of vain thoughts. Remember that the Lord sees you, and be fearful lest you anywise offend your brother, whom neither dispraise nor grieve, even by a look, and the Holy Spirit will love you and will Himself be your help in all things.
Any soul which has lost its peace must repent, and the Lord will forgive its sins, and then peace and joy will visit the soul. There need be no witnesses, for the Holy Spirit is the witness of the remission of sins. Here is a sign of forgiveness: if you have come to hate sin, then the Lord has forgiven your sin.
This prayer should never be absent from you: 'Lord Jesus Christ, Son and Logos of the living God, through the Theotokos and all the Saints, have mercy upon me, Thy sinful and unworthy servant.' (This is the actual Jesus Prayer: 'O LORD JESUS CHRIST, SON OF GOD, HAVE MERCY UPON ME, A SINNER.') Always say this prayer both with your mouth and with your mind, day and night, wherever you may be, whether eating, walking, working, or sitting. Always meditate on it, as it benefits you a great deal, frees you here from every evil, delivers you there from eternal Hell, and renders you worthy of going to Paradise, our heavenly country.
Beguiling and deceptive is the life of the world, fruitless its labor, perilous its delight, poor its riches, delusive its honors, inconstant, insignificant; and woe to those who hope in its seeming goods: because of this many die without repentance. Blessed and most blessed are those who depart from the world and its desires.
Whoever repents sincerely is prepared to withstand any sorrow: hunger and homelessness, cold and heat, illness and poverty, humiliation and banishment, lies and slander, for the soul seeks God and does not concern itself with anything worldly, but instead prays with a clear mind.
Where there is pride there cannot be grace, and if we lose grace we also lose both love of God and assurance in prayer. The soul is then tormented by evil thoughts and does not understand that she must humble herself and love her enemies, for there is no other way to please God.
The lower you descend, the higher you ascend; and when, like the psalmist, you regard yourself as nothing before the Lord (cf. Ps. 39:5), then imperceptibly you will grow great. And when you begin to realize that you have nothing and know nothing, then you will become rich in the Lord through the practice of the virtues and spiritual knowledge.
We must always pray to the Lord to tell us what to do, and the Lord will not let us go astray. Adam was not wise enough to ask the Lord about the fruit which Eve gave him, and so he lost paradise. David did not ask the Lord whether it would be a good thing if he took Beth-sheba to wife, and so he fell into the sins of murder and adultery. So with all the saints who sinned: they sinned because they had not called upon God to enlighten and help them. St. Seraphim of Sarov said, ‘When I spoke of myself I was often in error.’
When you see someone suffering great dishonor, you may be sure that he was carried away by thoughts of self-esteem and is now reaping, much to his disgust, the harvest from the seeds which he sowed in his heart.
The Saints were people just like ourselves. Many of them started with grievous sins but through repentance they attained the Kingdom of Heaven. And every one who comes to the Kingdom of Heaven does so through repentance which the Merciful Lord granted us by His sufferings. In the Kingdom of Heaven, the holy Saints look upon the glory of our Lord Jesus Christ; but through the Holy Spirit they see, too, the sufferings of men on earth. The Lord gave them such great grace that they embrace the whole world with their love. They see and know how we languish in affliction, how our hearts have withered within us, how despondency has fettered our souls, and they never cease to intercede for us to God.
Be glad and rejoice that you were granted to be pious Orthodox Christians. Likewise again cry and mourn for the impious and unbelievers who walk in darkness, in the hands of the devil.
If you love Christ God, then endure as He endured, and do all that is pleasing to Him. He taught and did. Unfailingly your love should be such as does good, endures, is disturbed by nothing present, and in everything ever thanks Him not with words and tongue, but with very deeds.
If you will pray for your enemies, peace will come to you; but when you can love your enemies - know that a great measure of the grace of God dwells in you, though I do not say perfect grace as yet, but sufficient for salvation. Whereas if you revile your enemies, it means there is an evil spirit living in you and bringing evil thoughts into your heart, for, in the words of the Lord, out of the heart proceed evil thoughts - or good thoughts.
