Knowledge enjoins all those who journey in its path to investigate, according to its laws, the end of anything before making a beginning, and thus to commence; lest the end of the thing prove unachievable by the limit of human ability, and labor be spent in vain, and lest the thing prove difficult and impossible to realize.
But what says faith? ‘All things are possible to him that believeth,’ for to God nothing is impossible. O unspeakable wealth, O ocean rich in its billows and its marvellous treasures and mighty floods of the power of faith! How filled with boldness, how replete with sweetness and hope is the journey accompanied by faith! How light are faith’s burdens, how sweet its labors!
St Isaac of Syria, Homily 52
