I don't really buy Stanley's illustration, not because I don't see distinctions in heaven, but rather because it is far too weak and paints a picture other than that which we see in Scripture.
Heaven or eternity to come once the Last Day has come and God's righteous judgments are complete will be a place where life goes on. There will be kings and commerce, roads and travel, music and worship, we will eat, we will know and be known, there will be animals and children, and at the center of all is God.
It is because of this "heavenly choir" aspect that Stanley and so many others paint that many Christians cling so hard to this worldly life. They are terrified that heaven will be one big (and everlastingly boring) church service. Then we work to drum up enthusiasm for that scenario, when in fact we don't really have much at all.
God said that He would create a new heaven and a new earth as part of His plan for eternity. We might take a few clues from His first creation, then realize that what God intended WILL come to pass. He cannot be thwarted! All this time of sin curse, suffering, loss, and pain will be nothing compared to the restoration of His glory as He always and first intended. That vision is TRULY something to cause enthusiasm and we will discover that we lack nothing we have here, save the pain and curse of sin and untruth.
This concept is everywhere within Scripture for those who can open their eyes to see. But instead, we key in on a couple passages and make that our complete vision. So wrong and so less than God plans.
