As a Noachide, surely you don't believe that just because God ordained something, He won't decide to turn it upside down and do something new, do you?
As a child of the Reformation ... certainly not.
Heh, Jesus promised His Church would never fall, so if you're insinuating that Jesus turned His Church upside down, you're only calling Him a liar. We can go on for another 800 posts on the immense latitude you'll apply to the definition of the word "Church", but suffice to say, we'll disagree.
God never made any promises that there wouldn't be an Earth v 2.0 or a fulfillment of the Torah in the new covenant. He did promise that He would never destroy the earth again with the waters of a flood. In fulfillment of this promise, He's continually saving the Earth through the life-giving waters of Christ.
