What did Jor-El mean by "They will join you in the Sun?"

I always thought that he meant Superman would help us advance our race and we'd unlock our hidden Kryptonian power. But what does it mean? Explain.

it's a metaphor for ascending to greatness

I heard someone surmise that it could be a hint about the upcoming Justice League. Personally, I think it's just a metaphor for making the world a better place.

@jonny_anonymous:

So Superman would help us ascend into greatness? How

Sorry I don't read the comics, I just saw it in the man of steel trailer

@pfcoolio14: By giving us an example of who we can be. Truth, justice, sacrifice, tolerance. What makes Superman a hero for most is not his power set, but rather what's in his heart.

@nappystr8:

That's a really big prediction that his father made about him

This...should be on a T-shirt.

I'd wear it.

He was quoting All-Star Superman. In that Superman literally goes into a sun. but yeah, it's pretty clearly a metaphor for ascending to our potential greatness.

@nappystr8:

How did he know Kal would be like that?

Maybe Jor-El wants to spread a virus to make everyone super ?

The Superman origin story changes a lot, but one of the elements that usually seems to occur is that Jor-El specifically chose Earth for Clark to go to, and specifically chose the Kent family to send him to, because of our/their inherit goodness. Hoping that they would shape him into the best man he could be. So there's a bit of chicken and the egg to it.

Maybe Superman will become an advocate for more funding to space projects ?
