The way that I understood him to be using the term "universal salvation" from what he had to say about it was that everyone will make it to heaven and that no one will will go to Hell regardless of what we believe/don't believe or do in life. It is true that salvation is universal in that it's available to everyone who asks God/Jesus to forgive them for their sins but not available to people who refuse to accept it/ask for it/repent of their sins. God/Jesus will never force anyone to be saved. It is a choice. If a person chooses to live in sin without repenting of them...they will most certainly go to Hell.
