Absolutely.
One possible interpretation says this COULD be different than the scriptural account of Jesus coming in the clouds to receive believers in the rapture.
So you seem to be admitting that Jesus' "coming in clouds" may not be witnessed by all men on the earth. Is that correct?
It is no secret coming.
Depends on whether or not everyone sees it. No?
It is a matter of the touchdown on Mt Olives. (Sorry, Notre Dame, this is the real "Touchdown Jesus.")
I'm not sure you're familiar with these issues, so your questions appear to be off the mark.
