Discipleship demands stepping in to help those afflicted by injustice, and the ways in which Christians do so must be compatible with Jesus's ethic of nonviolence.
If people used to go to church to find hope, they're leaving the church because many of them are tired of worshiping with neurotic and, in some cases, even psychotic people who have, for all practical purposes, given up on the world.
We never "find" hope at all. Rather, we create hope, and we do so through love, empathy, and compassion. We create hope through the care we bring to any situation.
