...whoever is guided solely by his own judgment and decision will never climb up to the summit of perfection and will not fail to be the victim of the devil's ruinous power to delude.
John CassianThe 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...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.
John CassianWhen we say 'hallowed be Your name' to God what we are really saying is 'Father, make us such as deserve knowledge and understanding of how holy You are, or at least let Your holiness shine forth in the spiritual lives we lead.' And this surely happens as men see our good works and glorify our Father in heaven.
