Reality always seems funny to the uninformed/credulous.
Well, I took your advice and got informed...I followed your link...And here's what I found...
2 Peter 3:10, 12 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up...Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
Problem here? No more so than it was in Olivet when we hear of the moon turning to blood and such. This is just the usual Jewish apocalyptic hyperbole, representing the refashioning of the social and political order -- not a literal description of history as it shall happen.
The author of your link doesn't believe the Bible to begin with...If you chose not to believe the book, you can make up anything you want...But hey, if this part isn't literal, how can you say for certain Jesus hung on a cross????
