...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 Cassian...we must first scrutinize thoroughly anything appearing in our hearts or any saying suggested to us. Has it come purified from the divine and heavenly fire of the Holy Spirit? Or does it lean toward Jewish superstition? Is its surface piety something which has come down from bloated worldly philosophy? We must examine this most carefully, doing as the apostle bids us: 'Do not believe in every spirit, but make sure to find out if spirits are from God'.
John Cassian...we know that God arranges the opportunities for salvation in different ways. Our situation is that we respond eagerly or in a laggardly manner to these opportunities made available by God to us. God made the call come out of your homeland; Abraham by coming out was exercising obedience. There was the instruction come into the land; it was done, and that was the work of obedience. But the addition which I shall show you has to do with the grace of God, who gave a command - and a promise.
John CassianIt is impossible for the mind to remain undisturbed by thoughts, but anyone serious about the matter can certainly permit them entry or drive them away, and although their origin does not lie entirely under our control we can choose to approve of them and to adopt them.
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.
