Thus also we who in our lives are ill of shameful lusts and reprehensible excesses, and other inflammatory effects of the passions, need the Saviour. And He administers not only mild, but also stringent medicines. The bitter roots of fear then arrest the eating sores of our sins. Wherefore also fear is salutary, if bitter. Sick, we truly stand in need of the Saviour; having wandered, of one to guide us; blind, of one to lead us to the light; thirsty, “of the fountain of life, of which whosoever partakes, shall no longer thirst;” dead, we need life; sheep, we need a shepherd; we who are children need a tutor, while universal humanity stands in need of Jesus; so that we may not continue intractable and sinners to the end, and thus fall into condemnation, but may be separated from the chaff, and stored up in the paternal garner.
Clement of Alexandria, “The Instructor, Book 1”
