You err again. The promised land is not to be identified as Heaven.
You claim that I err, yet you insert something that I never stated. Thus, the error is your own thoughts. As
@bbyrd009 recently stated, and I paraphrase: metaphorically speaking, we are in the wilderness. Which happened to be my thoughts as I wrote my former reply, however I intentionally choose to leave them out.
There is much fighting and war in the promised land once Israel got there. The promised land is a picture of the believer walking in victory over the many trials down here. It is a picture of the believer walking in faith and in the Spirit.
Yet, when Jesus returns, the first resurrection takes place, and the "millennial reign", there is still:
Rev 20:7 And when the thousand years may be finished, the Adversary shall be loosed out of his prison, 8 and he shall go forth to lead the nations astray, that are in the four corners of the earth--Gog and Magog--to gather them together to war, of whom the number is as the sand of the sea;
Then there is the ultimate "promised land", that is the new heavens and the new earth.
The wilderness, where a whole generation died, is a picture of the believers who fails to enter that victorious walk of faith. And why did he not enter? Not because of sins, though he sinned. Because of unbelief. A lack of faith. (Heb. 3:17-19)
Indeed. Because they did not heed the voice of YHVH and obey His Instruction. It was reckoned as "unbelief". They did not believe "God" enough to obey His Instruction.
Speaking of a "victorious walk of faith":
2 Tim 2:5 And if also a man contend in the games, he is not crowned, except he have contended lawfully.
Which by that alone, reveals there is no crown, there is no reward, for those whose "victorious walk of faith" has not been done lawfully.
(Matt. 7:23) is not a picture of losing salvation. The Lord says "I never knew you".
Indeed, for as in the wilderness, those who refuse the Instruction, those who do not run the race lawfully, it is as though they never believed.
Mat 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven;
but he that doeth the will of my Father who is in heaven. 22 Many will say to me in that day, Lord, Lord, did we not prophesy by thy name, and by thy name cast out demons, and by thy name do many mighty works?
Based upon v22, those to whom heard it was said: "I never knew you", sure thought they knew him. In the parallel account in Luke:
Luk 13:25 When once the master of the house is risen up, and hath shut to the door, and ye begin to stand without, and to knock at the door, saying, Lord, open to us; and he shall answer and say to you, I know you not whence ye are; 26
then shall ye begin to say, We did eat and drink in thy presence, and thou didst teach in our streets; 27 and he shall say, I tell you, I know not whence ye are; depart from me, all ye workers of iniquity.
Ye that work what?
Mat 7:23 And then will I profess unto them, I never knew you: depart from me,
ye that work iniquity.
As I asked of you before: What is "unrighteousness"?
Joh 14:21 He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself unto him.
Joh 15:14 Ye are my friends, if ye do the things which I command you.
(Heb. 10:27) is judgement on the believer, but it is not the believer that is devoured, it is the adversaries.
As you state, the "believer". And as you yourself pointed out with regard to the wilderness, those that did not uphold the Instruction, were reckoned as "unbelievers". And thus,
consumed in the wilderness. So according to your own words, you are without excuse.
The believer suffers as God destroys that which is destroying the believer. The believer is still the believer. (Heb. 10:30) "...And again, The Lord shall judge his people." (Heb. 10:39) "But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul."
Just as in the wilderness, those who shrank back from upholding His Instruction.
And, what was this wilfull sin that the Hebrew Christians were going back to? The Law. They had believed on Jesus Christ but now due to persecution by the Jews they were going back to the Mosaic system of law and animal sacrifice. They were meeting in the synogogues and not meeting with their fellow Christians.
So let me get this absolutely straight: You are clearly stating that upholding His Instruction, that His "law" is "willful sin"? I am reading you correctly?
(Deut. 9:4) proves nothing concerning a loss of salvation. If anything it proves the believer doesn't obtain any form of salvation by works.
Deu 11:26 Behold, I set before you this day a blessing and a curse: 27 the blessing, if ye shall hearken unto the commandments of YHVH your God, which I command you this day; 28 and the curse, if ye shall not hearken unto the commandments of YHVH your God, but turn aside out of the way which I command you this day ...
Deu 30:15 See, I have set before thee this day
life and good, and death and evil; 16 in that I command thee this day to
love YHVH thy God,
to walk in his ways, and to keep his commandments and his statutes and his ordinances, that thou mayest live and multiply, and that YHVH thy God may bless thee in the land whither thou goest in to possess it.
Deu 30:17
But if thy heart turn away, and thou wilt not hear, but shalt be drawn away, and worship other gods, and serve them; 18
I denounce unto you this day, that ye shall surely perish; ...
Deu 30:19 I call heaven and earth to witness against you this day, that I have set before thee
life and death, the blessing and the curse: therefore
choose life, that thou mayest live, thou and thy seed; 20 to love YHVH thy God,
to obey his voice, and to cleave unto him; for
he is thy life, and the length of thy days; that thou mayest dwell in the land ...
Perhaps you missed the parallel between Deuteronomy 9 and Romans 11.
(Rom. 11:18) is speaking to salvation being found in Israel or the Gentiles. Before, it was in Israel. (John 4:22) "Ye worship ye know not what:we know what we worship: for salvation is of the Jews."
Really? John 4:22? That's your "prooftext" regarding Romans 11:18? I don't even have to look that up. He was speaking to a Samaritan woman. It is telling Gentiles not to glory over those broken off. Just as Deuteronomy 9:4 was telling them not to think in their hearts ... So also should not we think such a thing.
Rom 11:25c ... lest ye be wise in your own conceits,
Rom 11:19 Thou wilt say then, Branches were broken off, that I might be grafted in. 20 Well; by their
unbelief they were broken off, and thou standest by thy faith. Be not highminded, but fear:
This echoes Deuteronomy 9:4.
But now the door is open to the Gentiles. (Eph. 2:11-13) But just as God closed the door to Israel, God can close the door to the Gentiles and reopen it to Israel. And why did he close the door? Sin? Yes, the sin of unbelief, which you quoted. (11:20) And we stand how? By faith. Which you quoted. (11:20)
Indeed.
Rom 11:21 for if God spared not the natural branches,
neither will he spare thee. 22 Behold then the goodness and severity of God: toward them that fell, severity; but toward thee, God's goodness,
if thou continue in his goodness:
otherwise thou also shalt be cut off. 23 And they also, if they continue not in their unbelief, shall be grafted in: for God is able to graft them in again.
