Exactly nailed. There have always been 2 classes!!! 2 always!!!!
The Heavenly Class the little flock.
The Earthly Class the great crowd.
At the risk of sounding argumentative there are actually three classes.
The heavenly "little flock" class. Those whom Jesus allegedly made a direct covenant with to rule in heaven with him, which could be a relatively small but limited number. (Figurative 144,000?)
The heavenly "great crowd". Those who are now claiming to be anointed and going to heaven as part of a final gathering. (A large but unspecified number)
The "Other Sheep" who profess to want to live forever on earth petting pandas, wearing suits and dresses, and never not smiling as they pick fruit in their dress up clothes.
This was, if I remember correctly, somewhat of a teaching in the twenties, that there were two classes of heaven-bound partakers.
All-in-all it is as a CO once said, "No matter how you slice baloney it is still baloney."
