They asked Abba Sisoes, ‘If a brother sins, surely he must do penance for a year?’ He replied, ‘That is a hard saying.’ The visitors said, ‘For six months?’ He replied, ‘That is a great deal.’ They said, ‘For forty days? ‘He said, ‘That is a great deal, too. ‘They said to him, ‘What then? If a brother falls, and the agape is about to be offered, should he simply come to the agape, too? ‘The old man said to them, ‘No, he needs to do penance for a few days. But I trust in God that if such a man does penance with his whole heart, God will receive him, even in three days.’
You must never be afraid, if you are troubled by a flood of thoughts, that the enemy is too strong against you, that his attacks are never ending, that the war will last for your lifetime, and that you cannot avoid incessant downfalls of all kinds. Know that our enemies, with all their wiles, are in the hands of our divine Commander, our Lord Jesus Christ, for Whose honour and glory you are waging war. Since He himself leads you into battle, He will certainly not suffer your enemies to use violence against you and overcome you, if you do not yourself cross over to their side with your will. He will Himself fight for you and will deliver your enemies into your hands, when He wills and as He wills, as it is written: ‘The Lord thy God walketh in the midst of thy camp, to deliver thee, and to give up thine enemies before thee’ (Deut. xxii, 14).

Until a man’s earthly life finishes its course, up to the very departure of the soul from the body, the struggle between sin and righteousness continues within him. However, high a spiritual and moral state one might achieve, a gradual or even headlong and deep fall into the abyss of sin is always possible. Therefore, communion of the holy Body and Blood of Christ, which strengthens our contact with Him and refreshes us with the living streams of the grace of the Holy Spirit flowing through the Body of the Church, is necessary for everyone.

Grumbling is caused by misery and it can be put aside by doxology (giving praise). Grumbling begets grumbling and doxology begets doxology. when someone doesn’t grumble over a problem troubling him, but rather praises God, then the devil gets frustrated and goes off to someone else who grumbles, in order to cause everything to go even worse for him. You see, the more one grumbles, the more one falls into ruin.
Sometimes the devil deceives us and makes us unable to be pleased with anything; however, one can celebrate all things in a spiritual manner, with doxology, and secure God’s constant blessing.
+ St. Paisios of Mt. Athos, Elder Paisios of Mount Athos Spiritual Councils IV: Family Life
“But nothing causes such exceeding grief as when anyone, lying under the captivity of sin, calls to mind from where he has fallen, because he turned aside to carnal and earthly things, instead of directing his mind in the beautiful ways of the knowledge of God. So you find Adam concealing himself, when he knew that God was present and wishing to be hidden when called by God with that voice which wounded the soul of him yourself? Why are you concealed? Why do you avoid Him Whom you once longed to see? A guilty conscience is so burdensome that it punishes itself without a judge, and wishes for covering, and yet is bare before God.”
+ St. Ambrose Milan, Concerning Repentance, Book II
“Recollect the fall of the strong, that thou mayest remain humble under thy virtues. And think of the heavy sins of those who fell and repented; and of the praise and honour they received afterwards, so that thou mayest acquire courage during repentance.”

“Do not fall into despair because of stumbling. I do not mean that you should not feel contrition for them, but that you should not think them incurable. For it is more expedient to be bruised than dead. There is, indeed, a Healer for the man who has stumbled, even He Who on the Cross asked that mercy be shown to His crucifiers, He Who pardoned His murders while He hung on the Cross. ‘All manner of sin,’ He said, ‘and blasphemy shall be forgiven unto men,’ that is, through repentance.”
