Jesus predicted the rise of Homosexuality in the last days through one of His sermons to the Pharisees, when he stated that, in the last days, things would be pretty much identical to what they were during the time of Noah and Lot.  The most defining thing of these time periods was the rampant levels of homosexuality that existed.  We currently see very similar circumstances to what it was like in those days, what with the rampant proliferation of the gay lifestyle, and it will continue to get worse until the Lord returns.
