Is There a Secret Collection of the Kingdom Citizens That Happens Before the Return of the Son of Man?

It's possible that a read somebody could have but if we were just looking at this text, nothing about this really gives the indication that there's a secret collecting of the people of god. It looks like the most natural reed here is that the son of man shows up in a way that's pretty evident and pretty noticeable to everybody. The point of it all is spelled out crystal clearly by jesus in the very next sentence. Therefore, keep watch, because you do not know on what day your lord will come.
