As is a grain of sand weighed against a large amount of gold, so, in God, is the demand for equitable judgement weighed against his compassion. As a handful of sand in the boundless ocean, so are the sins of the flesh in comparison with God's providence and mercy. As a copious spring could not be stopped up with a handful of dust, so the Creator's compassion cannot be conquered by the wickedness of creatures.
Isaac of Niniveh (7th century)
(quoted in Roots of Christian Mysticism)
