I hate to bring bad news, because obviously your mysterious 5000-year project is near-and-dear to you: Jesus will be returning soon, and one millennium thereafter we will have a new earth. So, unless those 5,000 years look backward....
And this new earth, this new world order won’t need better tools?
Also, perhaps you are better qualified to answer this, but isn’t that Holy reign for a period of 1,000 years.
1,000 years of study war no more followed by Satan’s final rebellion?
Shouldn’t we do all we can to give the side of good every advantage to prevail, not just on the spiritual plane (you’ve got that covered), but the physical plane as well?
