How is heaven different?

I’m in an online discussion with a non-Christian. Right now we’re talking about heaven. The most recent question is this:

So how is being in heaven any different than knowing the magnificence of God now? Do we develop a better understanding or appreciation there?

Sometimes the simplest questions can be the most challenging. As far as I can tell, the question is quite sincere.

I’ve given a short answer already. How would you answer this?
