To me, Julie Green is proven. I've been watching her for a while. She often has prophecies that are insignificant, even silly, but she has explained that these are things God gives to build up trust. Recent examples include "Kalamazoo will be in your news for an unusual reason" and "a goat will be in your news for an unusual reason." As a matter of self-discipline, I have not actively sought out news on either one, but both recently came to my attention. Those items, seemingly random and from diverse areas, defy an easy explanation unless she has a timewarp Reuters feed or an NSA insider connection. On items like these, she seems to be completely pass-through, commenting "I have no clue what that means, but He said to say it, so there you go." I was initially resistant to her, because her appearance and presentation remind me of ditzy cheerleaders and student body leaders from high school. But as with those examples, age teaches us to look beyond the surface appearance. The video linked by OP is a laughably disingenuous portrayal, as anyone who's seen her videos will recognize. Time will tell, and we will see. Those who believe without seeing are taking a leap of faith.

I had zero interest in modern-day prophets until 2020, when I was led to Kim Clement. Among other things, Kim talked about different types of prophets, and how some preach doom and lamentation, but how others like him prophecy good news and joyous occasions, and how they can represent different seasons in the Lord's plan. Other times they can represent different messages to different people for the same times.
