The first duty of a Christian, of a disciple and follower of Jesus Christ, is to deny oneself. To deny oneself means to give up one's bad habits, to root out of the heart all that ties us to the world; not to cherish bad desires and thoughts; to quench and suppress bad thoughts; to avoid occasions of sin; not to do or desire anything from self-love but to do everything out of love for God. To deny oneself means, according to the Apostle Paul, to be dead to sin and the world, but alive to God.
But, say the saints, now that you recognize the darkness in your own heart and the weakness of your flesh, you lose all desire to pass judgment on your neighbor. Out of your own darkness you see the heavenly light that shines in all created things reflected the clearer: you cannot detect the sins of others while your own are so great. For it is in your eager striving for perfection that you first perceive your own imperfection. And only when you have seen your imperfection, can you be perfected. Thus perfection proceeds out of weakness.
The more a man struggles to do good, the more fear grows in him, until it shows him his slightest faults, those which he thought of as nothing while he was still in the darkness of ignorance.
Self-accusation before God is something that is very necessary for us; and humility of heart is extremely advantageous in our lives, above all at the time of prayer. For prayer requires great attention and needs a proper awareness, otherwise it will turn out to be unacceptable and rejected, and `it will be turned back empty' to our bosom.
If anyone wants to drive out the demons, he must first subdue the passions, for he will banish the demon of the passion which he has mastered. For example, the devil accompanies anger; so it you control your anger, the devil of anger will be banished. And so it is with each of the passions.
On that day God will not judge us about psalmody, nor for the neglect of prayer, but because by abandoning them, we have opened our door to the demons.
A certain brother asked the Abbot Poemen, saying, 'What am I to do, Father, for I am troubled in sadness?' The old man said to him, 'Look to no man for aught, condemn no man, disparage no man: and God shall give thee rest.'
The adversary of our life, the devil, employs many devices to make our sins seem small to us. Often he cloaks them with forgetfulness, so that, after suffering a little on their account, we no longer trouble to lament over them. But, my brethren, let us not forget our offences, even if we wrongly think that they have been forgiven through repentance; let us always remember our sinful acts and never cease to mourn over them, so that we may acquire humility as our constant companion, and thus escape the snares of self-esteem and pride.
