But it's not the church that says that's what heaven will be like.
That's what the bible describes heaven as.
Eternal worshipping of god.
Want to do what you like?
No you don't. You want to worship god.
Feel like having some pizza?
No you don't. You're in heaven now you don't need to eat. 24/7 god worshipping. OH wait, there's no day or night. Just eternally singing. Singing praise to god.
Oh, you want to take a break?
You don't need one.
Because you don't need to breathe anymore.
So you can worship god forever.
"Excuse me god? Can I stop singing for a bit? My throat's sore..."
No it isn't. You're in heaven. there's no pain in heaven. Go back to singing. Forever.
"Can I stop standing here and singing? My legs are getting a little -"
No they aren't. Go back to singing god's praise.
