Hope, first of all, must be realistic. That is, hope can be hope only if it admits that which is darkest while urging toward the light.
Nothing glib, or blind, or deflective toward the depth of despair could be a contender for hope. If hope has not first been silenced before the profundity of evil and loss, then such a two-dimensional offering is more scandalous than fruitful. Realistic is not so much concerned with practicality as it is about truthfulness.
