I personally know several Mormons and they’re all very nice....too nice. There’s something very plastic about Mormons personally, sorta like watching an episode of a 1950’s sitcom.
May I point out that most Christian believers 'know' that Jesus had blonde hair and blue eyes.
Christian believers have a lot of 'made up stuff' in their 'religions' as well.
Those details are not what's important anyway. It's the CONCEPTS put forth that GOD is trying to 'reveal' to us.
As far as the notion of Kolob, again these are only ways that a different religion explains the unexplainable.
The Christian 'view' of heaven is merely what someone still on the material plane believes that spiritual existence is like.
While fanciful and pretty, it's not 'the truth'. We can't yet 'understand' the truth.
