Really saved, just professors, conditional saved, or what?
It is not a mystery and one does not have to guess who the epistle was written to. It was written to the Hebrews and the first 3 verses of the epistle is a dead giveaway of that fact.
1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
2 Hath in these last days
spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds (Aions = ages = time frames with beginnings and endings for specific Devine purposes);
3 Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;
So,
Ga 4:4 - But when
the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
Not the fulness of times like in Ephesians 1:10 but "the time."
So when was the fulness of the time? It was at the end of the age in which Jesus, the son of God appeared. That is not a guess.
See here:
He 9:24 For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself,
now to appear in the presence of God for us:
25 Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others;
26 For then must he often have suffered since the
foundation of the world (kosmos, the creation):
but now once
in the end of the world (aion)
hath he appeared to put away sin by the sacrifice of himself.
God made these ten tribes of Israel to be as gentiles, not ethnically but functionally, during this present age and would have builded his house with them had they believed. During this same time Jesus said that Judah, to whom he came in the flesh, would not be saved in this world (aion, He came under the dispensation of Law) neither in the one to come, which is the age of grace., the present one, because of their rejecting him as the Messiah.
Keep in mind that God is not speaking to individuals in these Hebrew Christian epistles but to the tribes of Israel Both Israel in the wilderness under Moses and these strangers under Jesus were led for 40 years to the entrance into their rest and refused to go in.
He 3:11 Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus;
2 Who was faithful to him that appointed him, as also Moses was faithful in all his house.
3 For this man was counted worthy of more glory than Moses, inasmuch as he who hath builded the house hath more honour than the house.
4 For every house is builded by some man; but he that built all things is God.
5 And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after;
6 But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.
There is a condition in verse 6 above that should not be forgotten when one reads chapter 6. One must remember that Hebrews was written as late as 68 AD, two years before the dispersion in AD 70. Jude wrote about those who were candidates for the transforming gospel of Jesus Christ and cursed the law keeping Jewish teachers who persuaded them to remain in the Jews religion. John would write in his first epistle as late as 90 AD these words.
1 Jn 2:19: They (the many antichrists) went out from us but they were not of us; for if they had been of us they would no doubt have continued with us, but they went out, that they might be made manifest that they were not all of us.
It is interesting to me to see to whom these apostles preached and that we have no Bible record of any of the 12 ever going to gentile lands except where those strangers lived. Paul was the only apostle to go west to Europe as far as I can tell.
Ga 2:6 But of these who seemed to be somewhat, (whatsoever they were, it maketh no matter to me: God accepteth no man s person) for they who seemed to be somewhat in conference added nothing to me:
7 But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;
8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles)
9 And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.
10 Only they would that we should remember the poor; the same which I also was forward to do.
One should read this whole context for there is much to know and God is to be praised for his marvelous wisdom in the church.
God is a God who fashioned time in dispensations for the cause of accomplishing purposes in those time frames and he wrote his Bible in a dispensational framework that must be understood dispensationally. Within those dispensations there are operational transitions of God because he is the member of the Godhead who is in charge of operations. See 1 Cor 12:4-6
