Following the thinking on this thread I have also come up with a Biblical logical reason why the 144k is not all that reach Heaven. I have tried to use this but was given the wall of denial and diversion. Here it goes:
In Galatians 4:21-31, Paul is speaking of the two covenants in an allegory between Hagar and Sarah. Those that were of Hagar were born in the ordinary way (Jewish descent) and those born of Sarah were a result of a promise (born by the power of the Spirit).
Starting at verse 24 Paul goes into explaining the meaning of each Sarah and Hagar and to which Jerusalem they belong to. Hagar stood for the present city of Jerusalem and Sarah stood for the Jerusalem from above. The Jerusalem from above was free, just like Sarah in the allegory. This is the New Jerusalem spoken of in Revelation chapter 21 which is from above. In Verse 27 (a quote from Isaiah 54:1) it says that the children of the desolate woman (Sarah) will outnumber those of the woman with the husband (Hagar). It goes on in Isaiah to explain that this group will be much greater in number than the children of "Hagar".
So all of that being said, how can the New Jerusalem (Rev chapter 21)consist of only the 144,000 if Sarah's(Jerusalem from above) descendants will out number Hagar's (Earthly Jerusalem)?
At Gal 4:24 “24 These things may be taken as a symbolic drama; for these women mean two covenants, the one from Mount Si′nai, which bears children for slavery and which is Ha′gar.”
If we look to see the history of this covenant at Mount Si’nai it takes us back to Exodus 19:1-5 and the Ten Commandments at Exodus 20. This took place three months after the Israelites left Egypt (Exodus 19:1) and at that time there were 600,000 men not including the women and children (Exodus 12:31-38). These were men of 20 years of age and older (Exodus 38:26). So rightfully there were close to 1.2 million people (women and children included) in all if not more. This is the covenant represented in Gal 4:25 as I understand it.
After establishing a number (could be more) in the covenant of Hagar, we know that from the scripture in Isaiah 54:1 that the other covenant mentioned in Gal 4 (Sarah) is to outnumber the first. This puts a problem with the 144,000 being the Heavenly Jerusalem/Jerusalem from above/New Jerusalem as there were more than 600,000 in the covenant with Hagar!
