Rapture May 21st?

"But the day and hour no one knows, not even the angels of heaven, but My Father only"
Matthew 24:36

This Saturday, May 21st, has been set as the day of the rapture of the church, at least according to Harold Camping of Family Radio.  Mr. Camping and his followers have purchased billboards across the country proclaiming: Save The Date!...Return of Christ May 21,2011.  Camping who is a trained civil engineer started his radio ministry back in 1958 and sends out his messages over 150 radio stations.  He teaches that he figured out the date of the rapture using a complicated mathematical formula tied to the date of the Genesis flood.  Mr. Camping also predicted that the rapture would take place back in 1994 (oops).  When the rapture did not take place in 1994, he said his mathematical formula was off.  There are some other things about his teachings that, like his mathematical formula, are a little off.  He teaches that believers can not have assurance of salvation, that Jesus died twice (what!?), and he forbids communion and baptism.  There is actually more the he is off on, but you get the idea.
The media has picked up on this story, and of course when the rapture doesn't take place on Saturday at 3:00pm, he will be depicted as a nut case along with all others who believe in the rapture.  I can't disagree with the nut case description, but I am saddened to be lumped in with Camping and others who have failed in picking the date of the Lord's coming for His church.  The Lord has said so plainly that we won't know the day of His coming, so when people claim to know the day, it distracts from and minimizes, the reality of the rapture.  By the way, you are not a nut case if you believe in the rapture, in fact scripture says belief in the rapture, brings comfort, edification, and is our blessed hope (1 Thessalonians 4:18; Titus 2:13).  Today, even non Christians are wondering at world wide events, and trying to make some sense out of all the political, economic, and even natural upheavals.  The Lord is coming back, and all the false predictions will not speed up, nor slow down His coming.  Ours is not to predict, but to be faithful, watching, and waiting.  Who knows, Jesus may come back before Saturday!
