Do not be daunted by the enormity of the world’s grief. Do justly, now. Love mercy, now. Walk humbly, now. You are not obligated to complete the work, but neither are you free to abandon it. (Attributed to the Talmud, Jewish rabbinic writings)

When we look at all the problems of the world—individual and social—we could easily be discouraged by it all. How can we resolve all the conflicts, meet all the needs? The least we can do—maybe it’s the most—is to deal with what we can right here, right now.
What does the LORD require of you? To act justly and to love mercy and to walk humbly with your God. (Micah 6:8)
