Taboo on heaven

I often wonder about what heaven will be like. Or should I more correctly (to my own theology) say what will the new earth be like, when Jesus reigns in all his glory.

 

I like to imagine the specifics of what we might do, what abilities might we have, how will we relate to one another and to God... but I've noticed in some circles a resistance to discussing things like this. I've heard it said that it "cheapens" the idea of God's kingdom.

 

I know I could never imagine what it will be like, but isn't it encouraging to let your imagination run wild and think of the best possible scenario that you can imagine, and know that the reality will be even better?

 

I like to imagine about best possible scenarios of what heaven could be like, and then take comfort in 1 Corinthians 2:9:

 

"No eye has seen,
no ear has heard,
no mind has conceived
what God has prepared for those who love him"

 

Are those people who don't want to imagine the specifics of heaven scared of the real thing not living up to what we've imagined?
