Those 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 ConfessorWhen like the patriarchs we learn to dig wells of virtue and spiritual knowledge within ourselves by means of ascetic practice and contemplation, we will find within us Christ the spring of life (cf. Gen. 26:15-18). Wisdom commands us to drink from this spring, saying, 'Drink water from your own pitchers and from the spring of your own wells' (Prov. 5:15). If we do this we shall find that the treasures of wisdom truly are within us.
Maximus the ConfessorDispassion and humility lead to spiritual knowledge. Without them no one will see the Lord.
Maximus the ConfessorHe who busies himself with the sins of others, or judges his brother on suspicion, has not yet even begun to repent or to examine himself so as to discover his own sins.
