Third Heaven?

I came across a reference to a "Third Heaven" in 2 Corinthians 12:2, while reading the Bible in church. I was told we should not only read the passage that the preacher is referencing, but also read some verses before and after to give more context to the verse. That is how I found this interesting reference to the "Third Heaven".

2 Corinthians 12:2
NIV : I know a man in Christ who fourteen years ago was caught up to the third heaven. Whether it was in the body or out of the body I do not know—God knows.

KJV : I knew a man in Christ above fourteen years ago, (whether in the body, I cannot tell; or whether out of the body, I cannot tell: God knoweth;) such an one caught up to the third heaven.

The "Third Heaven" seems to refer to "the sky, outer space, and then a spiritual heaven", the levels of heaven.

For more on the "Third Heaven", check out the references above or this link, heaven, which talks in depth about the third heaven and references to heaven in the Bible. And this article "What is Heaven like?" also describes the three heavens.

Also I found that some think that this "man" was Paul. He talked about himself in the third person to communicate on the same level with his audience, the Corinthians. (see http://www.crivoice.org/thirdheaven.html)

This is cool stuff and it is all in the Bible.
