The second request of the very pure soul is to see the coming of the Father's kingdom (cf. Mt. 6:10). What this means first of all is that each day Christ should reign among holy men. And this happens when the devil's power has been driven out of our hearts through the expulsion of sinful foulness and when God has begun to reign within us amid the good odors of virtue. With fornication vanquished, chastity rules; with anger overcome, peace is king; with pride under foot, humility is sovereign.
John Cassian...just as the edifice of all the virtues strives upward toward perfect prayer so will all these virtues be neither sturdy nor enduring unless they are drawn firmly together by the crown of prayer. This endless, unstirring calm of prayer... can neither be achieved nor consummated without these virtues. And likewise virtues are the prerequisite foundation of prayer and cannot be effected without it.
John CassianNo other virtue makes man more equal to the angels, than the imitation of their way of life.
John CassianFasts and vigils, the study of Scripture, renouncing possessions and everything worldly are not in themselves perfection, as we have said; theyare its tools. For perfection is not to be found in them; it is acquired through them. It is useless, therefore, to boast of our fasting, vigils, poverty, and reading of Scripture when we have not achieved the love of God and our fellow men. Whoever has achieved love has God within himself and his intellect is always with God.
John CassianWherefore a monk's whole attention should thus be fixed on one point, and the rise and circle of all his thoughts be vigorously restricted to it; viz., to the recollection of God, as when a man, who is anxious to raise on high a vault of a round arch, must constantly draw a line round from its exact centre, and in accordance with the sure standard it gives discover by the laws of building all the evenness and roundness required.
John CassianGod can be sensed when we gaze with trembling hearts at that power of his which controls, guides, and rules everything, when we contemplate his immense knowledge and his knowing look which the secrets of the heart cannot evade.
John Cassian...the souls of the dead [are] not deprived of their intellectual faculties but... they also are not lacking in feelings such as hope and sadness, joy and fear. They already have a foretaste of what is in store for them after the general judgment. Nor does it happen, as some unbelievers would hold, that upon leaving this world they are turned to nothing. Actually they live more intensely and they concentrate more on the praises of God.
