Paul was clear that the unchanged human being can not enter the Kingdom

I almost hate to do this but I can't seem to help myself...Which Kindgom are you referring to? The Kindgom of God, or the Kingdom of Heaven?

[PetroniusMaximus]

"The Kingdom of God, or the Kingdom of Heaven?"

I believe they are one and the same.

The term "Kingdom of Heaven" is unique to Matthew in the NT. Unless you posit that Matthew had inside information about a certain type of "Kingdom" that Mark, Luke, John, Paul and others didn't, it must be synonymous with "Kingdom of God."
