If you are enclosed within yourself through prayer, humility, and mourning, you will find a spiritual treasure -- only let pride and criticism be far from you.
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?
Having withdrawn from the palace to the solitary life, Abba Arsenius prayed and heard a voice saying to him, 'Arsenius, flee, be silent, pray always, for these are the source of sinlessness.'
The world is much stormier than the surging waves, and sin agitates it more than wind does the sea. There are times when the waters of the sea are calm, when the winds are concealed in their hiding places; but in the world waves of desire are ceaselessly whipped up, and the wind of deceit blows against the doors of the world’s vessels. Yet the day when it will abate is at hand.... Blessed is he who has completed his path in the world without falling into its snares.
Abba Poemen also said this about Abba Isidore that whenever he addressed the brothers in church he said only one thing, 'Forgive your brother, so that you also may be forgiven.'
No Christian believing rightly in God should ever be off his guard. He should always be on the look-out for temptation, so that when it comes he will not be surprised or disturbed, but will gladly endure the toil and affliction it causes, and so will understand what he is saying when he chants with the prophet: 'Prove me, O Lord, and try me' (Ps. 26:2 LXX). For the prophet did not say, 'Thy correction has destroyed me,' but, 'it has upheld me to the end' (Ps. 18:35 LXX).
Just as one cannot buy education or artistic skills for any price without working at it, so one cannot attain the habit of exercising the virtues without zeal and diligence.
Therefore silence, prayer, obedience; when you practice these virtues with the help of God, then you will know the light of Christ is within your soul.
A haughty person is not aware of his faults, or a humble person of his good qualities. An evil ignorance blinds the first, an ignorance pleasing to God blinds the second.
