We think we know a lot, but what we know is very little. Even all those who have striven all their life to bring progress to mankind — learned scientists and highly educated people — all realize in the end that all their knowledge is but a grain of sand on the seashore. All our achievements are insufficient.
So, the person who loves God values knowledge of God more than anything created by God, and pursues such knowledge ardently and ceaselessly.
Based on Elder Thaddeus of Vitovnica, St. Maximos the Confessor
