Allison Warden says her family is so sure, that they're putting up billboards across the country announcing the return of the Messiah on May 21, 2011.
"Christ is going to return and rapture his elect, and the people that aren't saved will be left," Warden told ABC11.
How is Warden so sure?
"In First Thessalonians 5:4, it says: 'But ye, brethren, are not in darkness, that that day should overtake you as a thief.' That was kind of the key verse for me when I was looking into it," she said.
Warden is a follower of controversial Christian leader Harold Camping - who says he's mathematically uncovered that May 21, 2011 is exactly 7000 years since Noah's flood. His radio show is broadcast in 38 states - but not North Carolina - so Warden says her family had to move here to spread the word.
"You're obligated to warn people, so I guess the first thing we're doing is attempting to warn people. The second thing we are hoping is they go to the scriptures, and what happens at that point is not our concern. It's not our business. It's God's business," Warden offered.
Part of that business has moved individuals to privately fund dozens of billboards. Warden has also started the website wecanknow.com and even wrapped her car with the warning.
But while the Bible does teach Jesus will return, most Christians believe the teaching that no man can know the date.
"I think, like many folks before, they are misguided because the Bible says no one knows the time when Christ will return other than God, and therefore we're not to be speculating as to when that's going to occur," explained Danny Akin who is president of the Southeast Baptist Theological Seminary in Wake Forest.
Akin says he's seen predictions like this one before.
"Those who get involved in setting dates have one tragic common characteristic, they've all been wrong," he offered. "If they happen to be right, then praise God. I'll be happy to join them in the Rapture. I believe Jesus can come today and I believe he may not come for a thousand years. That's on God's timetable not ours."
