...unless the grace of God comes to the help of our frailty, to protect and defend it, no man can withstand the insidious onslaughts of the enemy nor can he damp down or hold in check the fevers which burn in our flesh with nature's fire.
John CassianActually, all gifts have been given for reasons of temporal use and need and they will surely pass away at the end of the present dispensation. Love, however, will never be cut off. It works in us and for us, and not simply in this life. For when the burden of physical need has been laid aside in the time to come it will endure, more effectively, more excellently, forever unfailing, clinging to God with more fire and zeal through all the length of incorruption.
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 CassianTrue spiritual knowledge has sometimes flourished most grandly in some who were without eloquence and almost illiterate. And this is very clearly shown by the case of the Apostles and many holy men, who did not spread themselves out with an empty show of leaves, but were bowed down by the weight of the true fruits of spiritual knowledge: of whom it is written in Acts: 'But when they saw the boldness of Peter and John, and perceived that they were ignorant and unlearned men, they were astonished' (Acts 4:13).
John CassianWe must, with God's help, eradicate the deadly poison of the demon of anger from the depths of our souls. So long as he dwells in our hearts and blinds the eyes of the heart with his somber disorders, we can neither discriminate what is for our good, nor achieve spiritual knowledge, nor fulfill our good intentions, nor participate in true life; and our intellect will remain impervious to the contemplation of the true, divine light; for it is written, 'Man's anger does not bring about the righteousness of God' (Jms. 1:20).
