Why Did Jesus Die?

Most people would answer that Jesus died so we can go to heaven. But...

And he died for all, that those who live should no longer live for themselves but for him who died for them and was raised again (2 Corinthians 5:15).

He also died so that we could be freed from the selfishness of living for ourselves, rather than for him- seeking our own good, looking out for number one.

The only "problem" is that this thought doesn't fit with our American culture- then again, maybe it's not a problem after all. Maybe the modern culture is the problem.
