Doing justice means giving people their due. On the one hand that means restraining and punishing wrongdoers. On the other hand it means giving people what we owe them as beings in the image of God. Nick Wolterstorff says that, as a creature in the image of God, each human being comes into your presence with ‘claim-rights.’ That is, they have the right to not be killed or kidnapped or raped. Of course there is plenty of room for disagreement on the specifics of these things, but that’s my basic definition. Doing justice, then, includes everything from law enforcement to being generous to the poor. (I believe Job 29 and 31 include generosity as part of a just life.)
