Does Hugh Ross believe in the global flood?
Does he believe that there were humanoids who buried their dead and created cave paintings before the time of Adam?
Hugh Ross once told me in person that he didn’t believe in the literal reality of the cubical eternal city of Jerusalem (described in Revelation). I asked him why and he said it was because gravity wouldn’t allow it to remain intact. I’m a PhD engineer at a federal defense contractor, and it was at our onsite location where he said this. It was a strange conversation, because Ross seemed to think that the Creator of the Universe is constrained in his power by the forces of nature.
I’ve heard Hugh discuss the New Jerusalem multiple times, and he has not mentioned anything like your assertion. Instead, he merely points out there are no known objects that large in our universe with cubic shapes, because gravity rounds off their corners.
Therefore, Hugh says, when God does introduce that gigantic cube, it will be evidence that God no longer is using gravity. In His new heaven and new earth, Hugh says, God will introduce new laws of physics. Gravity will not be part of it. Nor, apparently, says Hugh, will electromagnetism, judging by the fact that our light source will be God Himself (Rev.22:5).
I’ll leave the flood and hominids for another time, because it is bedtime.
