For centuries, Christians have proclaimed that Jesus died, Jesus rose from the dead and Jesus will come again.
A survey conducted by the Pew Research Center and Smithsonian magazine in 2010 suggests that future hope remains strong.
A majority of American Protestants and about one-third of Roman Catholics told the pollsters they believed Jesus would definitely or probably return by the year 2050.
Pew senior researcher Greg Smith says that belief was strongest in the South and among people with a high school education or less.
About one-eighth of Americans said they didn't know if Jesus Christ would return by the year 2050 -- placing them in agreement with Jesus's declaration that no one knows the day or the hour when he'll return, except God the Father.
