People came to Jesus with concerned over the deaths of some Galileans whom Pilate had killed. Their questions came from a familiar Old Testament-related fear that suffering was the result of sin. Remember in the Book of Job that his friends accused him of being a sinner because of his suffering. God rebuked them for that belief.
Jesus said to them in reply,
“Do you think that because these Galileans suffered in this way they were greater sinners than all other Galileans? By no means!
But I tell you, if you do not repent,
you will all perish as they did!
Or those eighteen people who were killed
when the tower at Siloam fell on them—
do you think they were more guilty
than everyone else who lived in Jerusalem?
By no means!
But I tell you, if you do not repent,
you will all perish as they did!”
