Notice this part...and to bring in everlasting righteousness. Why would that be different from the following?
2 Peter 3:13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
Surely when this occurs, that would be the same thing as bringing in everlasting righteousness, I would think. Why wouldn't it be? If the 70th week has already been fulfilled and that there is now everlasting righteousness, then why are we still waiting for the same thing in the new heavens and a new earth?
