" In the same manner as the sea, those who are swept away from the course leading to the harbor correct their aim by a clear mark, looking for a lighthouse on high, or a certain mountain appearing. In the same manner Scripture by the example of Abraham and Sarah will direct us once more to the safe harbor of the divine will for those who have drifted out in the sea of life with a mind lacking a navigator. "
― Gregory of Nyssa , The Life of Moses
