Did Jesus Really Say He Was "Coming Soon"?

"Jesus is coming soon!" is a common expression in the evangelical church; but given that it has been 2,000 years since He left, skeptics frequently throw this expression out and ask "What gives?" Even stand-up comics sometimes use this in their routines to make fun of Christians and the Bible.

So what's going on? Is the Bible wrong? Is the Second Coming of Christ just another empty religious prophecy? Or is there another answer?
