Donna,

Thank you very much for your response.

I agree with you, Jesus is not having a meeting on mount Sion on earth during the tribulation, with the 144,000.

He is, rather, meeting with them on the mount Sion in heaven.

Also, as you pointed out, there is a warning to those thinking to meet the Messiah on earth, before the second advent.

Who, therefore, will they actually meet in those secret chambers, or out in the desert, instead?
