God's promise to Abraham was that his descendants would be innumerable as stars in the heavens and sands of the sea. This promise prophetically included the Gentiles and was ratified by the vision in Revelation 7 when the other sheep are presented before the throne.
Now adding the faithful in ancient Israelites to the 144,000 saved in 19 centuries and then injecting the modern unanointed WTS class formed after the start of the twentieth century.....we are still talking piddly numbers.
So if the formula is:
Faithful pre-first century Jews + 144,000 + WTS 20 th century “Other Sheep” = just millions.
Seems to me the WTS has a lot more converting to do as the great tribulation develops into full blown Armageddon...if Abraham is to get his promise.
