Did Jesus speak more about hell than heaven?

Over the years I have often heard sermons in which it is claimed that Jesus taught more about hell than heaven. I have always believed it because I never had the inclination to check up on those making that claim, I just assumed it was true, because why would someone make such a claim if it weren't true? However, I have found an article entitled "[Did Jesus speak more about Hell than about Heaven?](https://www.patheos.com/blogs/unfundamentalistchristians/2015/01/did-jesus-speak-more-about-hell-than-about-heaven/) " where that claim is challenged and in what I have seen so far it may very well not be true. I wonder if there is anyone else on this group that has already done a study on the veracity of this claim. Here is a [list of the actual verses](http://wp.production.patheos.com/blogs/unfundamentalistchristians/files/2015/01/jesus-heaven-hell.pdf ) used by the author.
