'The long-suffering man abounds in understanding' (Prov. 14:29), because he endures everything to the end and, while awaiting that end, patiently bears his distress. The end, as St. Paul says, is everlasting life (cf. Rom. 6:22). 'And this is eternal life, that they might know You the only true God, and Jesus Christ whom You have sent' (Jn. 17:3).
Maximus the ConfessorThose who, animal-like, live solely according to the senses... misuse God's creation in order to indulge the passions. They do not understand the principle of that wisdom which is revealed to all: that we should know and praise God through His creation and that by means of the visible world we should understand whence we came, what we are, for what purpose we were made and where we are going. On the contrary, they travel through this present age in darkness... with... ignorance of God.
Maximus the ConfessorInasmuch as you pray with all your soul for the one who has slandered you, so much will God reveal the truth to them who have believed the slander.
Maximus the ConfessorA man who has been assiduous in acquiring the fruits of love will not cease loving even if he suffers a thousand calamities. Let Stephen, the disciple of Christ, and others like him persuade you of the truth of this (cf. Acts 7:60). Our Lord Himself prayed for His murderers and asked the Father to forgive them because they did not know what they were doing (cf. Luke 23:34).
Maximus the ConfessorWithout the power of intelligence there is no capacity for spiritual knowledge; and without spiritual knowledge we cannot have the faith from which springs that hope whereby we grasp things of the future as though they were present. Without the power of desire there is no longing, and so no love, which is the issue of longing; for the property of desire is to love something. And without the incensive power, intensifying the desire for union with what is loved, there can be no peace, for peace is truly the complete and undisturbed possession of what is desired.
