John 9:3

The context

The chapter opens with a man blind from birth, and the disciples ask whose sin caused it, his or his parents'. The question assumes a tight correspondence between suffering and fault, which the book of Job had already challenged. Jesus denies both options and redirects the conversation to what is about to happen.

What it establishes

The verse denies that this man's blindness is a punishment for a specific sin by him or his parents, and it frames the situation as an occasion for God's work. It breaks the arithmetic that the disciples' question assumes.

What it does not establish

It does not explain why anyone suffers. The verse addresses one case and one mistaken inference; it offers no general theodicy, and it does not say all suffering displays God's work. Nor does it deny human sinfulness, or suggest that disability is a gift.

• If God is all-good, why does God allow natural disasters, i.e. earthquakes, hurricanes, and tsunamis?
• If God is all-powerful, all-knowing and all-loving, why does he permit starvation, child molestation, rape, torture and genocide? And don't tell me the victims suffer for Adam and Eve's sin!
