Q. Re: The Larger Earth Theory. Reading it brings to mind a question I have had for a long time. What about the Sun’s heat benefit for the earth? I truly believe that the New Jerusalem could provide the light needed for earth but I can’t understand how the earth will survive with the heat benefit gone. Are we not to believe all we have learned about how the universe was put together and how it works?
A. The Bible only mentions the sun’s light being replaced by the New Jerusalem. But common sense tells us that God will provide heat as well, because after a week without a source of heat, daily temperatures would only reach a high of around 0 degrees F (-18 Celsius). Within a few months to a year that would drop to minus 100 degrees F (-73 Celsius). This would be unsuitable for human life. Besides, in the Millennium Earth will enjoy a world-wide sub tropical climate.
By asking if we are to forget all we have learned about how the universe was put together and how it works you must be referring to the so-called scientific model. In the Genesis creation account there is no mention of the Sun providing heat for the Earth, just light. All the other things the Sun does were just assumed.
