Jesus’ answer puts paid to any easy-going vending-machine theology (one sin in, one punishment out). ‘He didn’t sin,’ replied Jesus, ‘nor did his parents. It happened so that God’s works could be seen in him.’ (John 9.1–3) Jesus, in other words, doesn’t look back to a hypothetical cause which would enable the onlookers to feel smug that they had understood some inner cosmic moral mechanism, some sin that God had had to punish. He looks forward to see what God is going to do about it.
