Tim Keller quoted in a Christianity Today article, here:
People look at people who are different and see them as inferior and deserving of their problems. It’s a way of feeling better than others, because our hearts don’t want to rest in the gospel of grace. Power is another idol, because justice requires being involved with people of other races and sharing power with them.
Another idol would be money, which serves the idol of security. In Deuteronomy 15, God says that if you care for the poor, he will provide for you. God knows that the reason people aren’t generous is that they are afraid. They say, “I need a lot of savings.” But God is saying, “That’s distrust. You’re looking to money to give you a feeling of confidence that I should be giving you.”
