"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)."
