Watch: Joe Biden Opens Up About His Son's Death and His Plans For 2016 on Colbert's Late Show

After weeks of speculation, we are still no closer to knowing if Joe Biden plans on running for president in 2016, but we are closer to understanding his thought process. The Vice President sat down with Stephen Colbert, who's on his third episode and looking rock-solid, to lay out where his head is at and to open up about some of the personal matters he's gone through as of late. 

After telling the gut-wrenching story about his recently deceased son, Beau Biden, the conversation went to a place most late-night interviews don't: faith.

The two explored how Biden's faith helped him get through rocky times. "My wife put up a quote from Kierkegaard," Biden said. "It read 'Faith sees best in the dark'."

Stephen Colbert recently opened up to the Daily Beast about his own devout Catholicism.

"I don't want to come off—" Biden stumbled after discussing his spiritual journey. Colbert helped him out: "You don't want to come off as Pious Joe, I understand." 

"Well, I'm not," the Vice President said, grinning. 

It's a surprisingly emotional interview that helps explain why Biden's decision to run, which is no doubt also informed by other developments, is such a difficult decision. Colbert, for his part, insisted he should run.

"I know it's an emotional decision to make," Colbert said. "I just want to say your experience of suffering and service is something that would be sorely missed in the race."
