So are you saying:
1) there will be no work in the new Heaven and the new Earth? If so, what scripture are you deriving this from?
See above
2) there will literally no no day and night? If so, what scripture are you deriving this from?
Rev.21.23-25 and Rev.22.3-5
Do we take that as there will literally be no more stars and planets orbiting them and rotating on an axis anywhere in the universe (since that is what constitutes a day, as far as my non-scientific brain can understand)?
3) there will not be a command from God to keep the moral law?
What would be the purpose? As a rule of life (in the third use of the law) just like how it is in our lives currently Will commands from God cease entirely and we will be left to do whatever we desire since the only things we will desire are good things?
I'm not sure what you mean by "commands" Neither do I but I guess I’m just getting at the idea that anything that God would tell us/ask us to do in Heaven would be a command and therefore be related to the moral law in some way I think I know where the Bible might support that idea but I’ll ask anyway: what scripture are you deriving this from?
Romans can you help me out and give me specific chapters or passages?
