I will adapt a "Christendom" joke to the "Waiting on Jehovah" idea.
This terrible flooding occurred in conjunction with Hurricane Katrina and one man in his 70's decided that he would not simply abandon his home in the flood zone because "the lord will provide." When the police car showed up to help him out before the roads were impassible, he said "I am staying. The lord will provide." Eventually, he was on the second floor because the water rose so high. A boat pulled up to his window and a man tried to talk him into leaving. "No, thanks. The lord will provide." So later, he's on the roof and another boat goes by with the same outcome. Finally, he's on the chimney and a helicopter pilot on the loudspeaker says "We'll send you a rope." He pushes off the rope and says "The lord will provide."
Well, he drowned. At the pearly gates, he asks St. Peter why the lord did not provide. St. Peter says "According to my records, the lord sent a police car, two boats, and a helicopter. I think he provided."
So maybe an answer to "We will wait on Jehovah" could include how current research can be Jehovah's clear answer. "Maybe Jehovah is telling you that 607 is wrong and everything based on 607 is wrong."
