My Father’s mansion has many rooms and many realities. Let those who have eyes see them.
Yes, but the materialist presumes that all other “room”s must be natural worlds—their dogmatic evidence-immune assumption is that there is nothing else. I think the assumption is based on the pure irrational animal senses...a rather immature childish philosophy, particularly since discoveries of sub atomic physics has shown such sensibilities are not reliable guides to reality.
Btw, were you trying to quote Jesus here? If you meant John 14:2 every translation I have checked has not mentioned "many realities" in this verse nor close to it. Nor do I recall any place in the Christian bible linking "many rooms" or "many realities" to something that those who have eyes are expected to see...but perhaps I have missed something? Or perhaps you weren't trying to quote Jesus here?
