Captain America in the Bible

Okay, pop quiz time, what is the origin of the quotation below?

“We often suffer, but we are never crushed. Even when we don’t know what to do, we never give up.”
– ???

Back in August, to coincide with the anniversary of 9/11, there was an online survey conducted by Harris Interactive on behalf of American Bible Society. The survey found that more Americans attributed the above quotation to Captain America, Martin Luther King, and President George W. Bush than to St. Paul.

In total, 63% believed the words came from somewhere other than 2 Corinthians 4:8.

Who says Biblical literacy is down?
