“We must not miss what this [Christ's once for all death on the cross] implies. It means that no religious observance or good behaviour on our part could ever earn our forgiveness. Yet a great many people accept the caricature of Christianity which claims that we can. They see religion as a system of human merit. God helps those who help themselves, they say. But there is no way that this view can be reconciled with the cross of Christ. He died to take away our sins for the simple reason that we cannot remove them ourselves. If we could, his atoning death would be unnecessary”
