The distinction made is He comes for the Covenant seed....others are passed by.
There is only one way to heaven and that is through the new or everlasting covenant. That, after all, is Paul's point in Romans 9:7-11
For they
are not all Israel who
are of Israel, 7 nor
are they all children because they are the seed of Abraham; but, “In Isaac your seed shall be called.”8 That is,
those who are the children of the flesh, these are not the children of God; but the children of the promise are counted as the seed. 9 For this
is the word of promise: “At this time I will come and Sarah shall have a son.” 10 And not only
this, but when Rebecca also had conceived by one man,
even by our father Isaac 11 (for
the children not yet being born, nor having done any good or evil, that the purpose of God according to election might stand,
not of works but of Him who calls)
And again:
Rom 4:1 What then shall we say that Abraham our father has found
according to the flesh?2
For if Abraham was justified by works, he has something to boast about, but not before God.
The only way to heaven is through the New Covenant. By the works of the law no flesh will be justified in His sight. That's the Old Covenant. Those who insist on heaven by works are under the Old Covenant.
