Tony Stark (Robert Downey, Jr.) is so successful making weapons of war that he is known as “The Merchant of Death.” He even laughs that he would “be out of a job with peace.”
He visits the Middle East and is ambushed, seriously injured by a bomb made by his own company, proving Jesus’s observation that those who live by the sword die by it (or are at least delivered to death’s door).
Tony is able to live only with the help of an electromagnet keeping shell fragments from entering his heart. But he has an even greater change of heart – he decides to no longer manufacture weapons.
When Stark survives the ambush, he thanks the man who saved him. “Don’t waste your life,” is the response, which contributes to his conversion. He takes this to heart – so to speak – and later explains his conversion: “I shouldn’t be alive unless it’s for a reason.”
Like Paul on his trip to Damascus, Stark“had my eyes opened” and he metaphorically fulfills the prophet Isaiah’s vision of swords beaten into plowshares.
It turns out that Stark was targeted for death by Obadiah, the man who had become a second father to Tony – doing Judas one better in the betrayal department.
