Many people believe that ‘justice’ is strictly the punishment of wrongdoing, period. They don’t think we should be indifferent to the poor, but when we help them they would call such aid charity, not justice. But Job says that if he had failed to share his food or his fleece—his assets—with the needy, that would have been a sin against God and by definition a violation of God’s justice. Of course, we can call such aid mercy or charity because it should be motivated by compassion, but a failure to live a lifestyle of radical generosity is considered injustice in the Bible. 

Our culture gives us a mixed message. It says: make lots of money and spend it on yourself; get an identity by the kind of clothes you wear and the places you travel to and live. But also do some volunteer work, care about social justice, because you don’t want to be just a selfish pig. However, Christians’ attitudes toward our time and our money should not be shaped by our society; they should be shaped by the gospel of Christ, who became poor so that we could become rich (2 Corinthians 8:9).
