The belief that everyone goes to heaven.  It is similar to inclusivism but goes beyond its scope to include all of humanity.

Like annihilationism, this belief stems out of God's love.  Proponents of this view hold that a loving God is incapable of sending people to hell. 

Limited universalism is a variation of universalism that states the devout of all religions go to heaven.  This at least makes religion worthwhile and not pointless.

Of course universalism appears to go directly against teachings of the Bible about heaven and hell.  Most importantly the question must be asked why Jesus had to die on the cross if belief in Him is unnecessary to get into heaven.
