According to Family Radio founder and pastor Harold Camping, yes. At 6:00 p.m., to be precise. For the past three months I have received anonymous cards in the mail that advocate preparedness and warn of the impending judgment that will surround the return of Christ. These postcards have postmarks from around the nation…Ohio, Indiana, Illinois, as well as here in Iowa. Conservative evangelicals usually are quick to agree that biblical prophecy does teach that Christ will return to earth again someday. But the prophetic word is also clear in stating that no one will know the precise time of Christ’s advent (Matthew 24:36), likening it to a “thief that comes in the night” unexpectedly (2 Peter 3:10).
Albert Mohler posted an article on his blogsite about Harold Camping, providing some detail about his background that I thought was well written. You can find the article here.
