"The Cross is not simply a lovely example of sacrificial love. Throwing your life away needlessly is not admirable — it is wrong. Jesus’ death was only a good example if it was more than an example, if it was something absolutely necessary to rescue us. And it was. Why did Jesus have to die in order to forgive us? There was a debt to be paid — God himself paid it. There was a penalty to be born — God himself bore it. Forgiveness is always a form of costly suffering."
