Just went to take a look at the link which you gave -
http://www.jw.org/en/publications/magazines/w20140815/jesus-sadducees-marriage-after-resurrection/
The last paragraph states:
Understandably, we may have many questions about life in the new world. Rather than needlessly speculating on the answers to those questions, we will just have to wait and see.
So we should not needlessly speculate. Fair enough
HOWEVER.....
If you read the 2nd paragraph of the answer, it states:
For years, our publications have said that Jesus’ words about the resurrection and getting married likely refer to the earthly resurrection and that those resurrected to life in the new world will evidently not marry.
So who was speculating??? By the WT's own admission, they are the ones who are guilty of it!!! After all, JW speculations are based on WT publications themselves!!!
