God’s word uses sarcasm to emphasize a point. It differs however, from the usual form of irony in its severity and evident spitefulness. It is used to condemn some action by seeming to order it, or decide the claims of those who are condemned.
The chief priest and scribes mocked Jesus as he hung on the cross. “Let this Christ, the King of Israel, now come down from the cross, so that we may see and believe” (Mark 15:32).
Jeremiah also had a word to say about the ineptitude of false gods and the foolishness of those who put their faith in them.
27 Who say to a tree, ‘You are my father,’
And to a stone, ‘You gave me birth.’
For they have turned their back to Me,
And not their face;
But in the time of their trouble they will say,
‘Arise and save us.’
28 “But where are your gods
Which you made for yourself?
Let them arise, if they can save you
In the time of your trouble;
For according to the number of your cities
Are your gods, O Judah.
The false gods could do nothing for man but sit there. Jeremiah uses sarcasm to help the reader notice the ridiculous notion.
