"It is Finished" (John 19:30). What Was "It?"

We are going to look at John 19:30 and what it means and does not mean in this Podcast.  The verse states: "When Jesus therefore had received the vinegar, he said, It is finished: and he bowed his head, and gave up the ghost" (John 19:30).  Does this mean, as some say, that salvation was completed?  You will get some clear answers in this episode.
