Surley Harold Camping is commiting a sin?

You have no need to worry for a couple of reasons. First, Harold Camping claimed the same thing he is claiming now back in 1994 and it didn't happen. Second, the Bible is clear on the fact that the Second Coming will come "Like a Thief in the Night", no one will know but God. Harold Camping is taking the Lord's name in Vein by making these claims, I'm sure he is making tons of money off of people he is deceiving.
