What I found interesting from that .pdf link above and how it potentially relates to current events was this:

As mentioned by Jesus in the Parable of the Tares/Weeds in Matthew 13:24-30, 36-43, this kingdom of Satan is allowed to coexist, and grow unhindered, alongside the kingdom of heaven/God until the 'harvest' at the end of the age.

In light of recent comments made by both Biden ("cornpop") and the media, the phrase, "Separating the wheat from the chaff" has become more prominently used, oddly. When detailing the Flynn case, ballot harvesting, and the economy, look at the number of times the media has worded their stories and news articles using these words -- unusual timing and phrase.
