I need to get back to you on this, Manfred.
Some of the verses do seem to indicate heavenly rewards, but most of the them don’t call it out specifically. Interesting post, though. Did you find this on a website?
Randy Alcorn is a former pastor and author, founder of Eternal Perspectives Ministry - http://www.epm.org/ He has much biblical analysis on this topic and that’s where I looked to for much of what I posted in my last response to you.
