5 And Moses indeed was faithful in all His house as a servant, for a testimony of those things which would be spoken afterward,
6 but Christ as a Son over His own house, whose house we are if we hold fast the confidence and the rejoicing of the hope firm to the end.
7 Therefore, as the Holy Spirit says: "Today, if you will hear His voice,
8 Do not harden your hearts as in the rebellion, In the day of trial in the wilderness,
9 Where your fathers tested Me, tried Me, And saw My works forty years.
10 Therefore I was angry with that generation, And said, 'They always go astray in their heart, And they have not known My ways.'
11 So I swore in My wrath, 'They shall not enter My rest.' "
12 Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God;
13 but exhort one another daily, while it is called "Today," lest any of you be hardened through the deceitfulness of sin.
14 For we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end,
Hebrews 3:5-14
JLB
That truth you have shared in part is applicable towards being of the firstfruits with Christ as standing apart from those that are Christ at His coming. May the Lord help you see the while picture.
1 Corinthians 15:22 For as in Adam all die, even so in Christ shall all be made alive. 23
But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming. 24 Then cometh the end, ....
So those abiding in Him will be partakers with Christ to inherit the eternal glory of being that vessel unto honour in His House that can never die like the angels.
Read Psalm 89 for God's promise to the seed that departed from Him under the New Covenant. This is why the foundation remains & only the works thereon are judged.
Psalm 89:27 Also I will make him my firstborn, higher than the kings of the earth. 28 My mercy will I keep for him for evermore, and my covenant shall stand fast with him. 29 His seed also will I make to endure for ever, and his throne as the days of heaven. 30 If his children forsake my law, and walk not in my judgments; 31 If they break my statutes, and keep not my commandments; 32 Then will I visit their transgression with the rod, and their iniquity with stripes. 33 Nevertheless my lovingkindness will I not utterly take from him, nor suffer my faithfulness to fail. 34 My covenant will I not break, nor alter the thing that is gone out of my lips. 35 Once have I sworn by my holiness that I will not lie unto David. 36 His seed shall endure for ever, and his throne as the sun before me. 37 It shall be established for ever as the moon, and as a faithful witness in heaven. Selah.
This is why they are still called His servants when getting their stripes when left behind.
Luke 12:40 Be ye therefore ready also: for the Son of man cometh at an hour when ye think not. 41 Then Peter said unto him, Lord, speakest thou this parable unto us, or even to all? 42 And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of meat in due season? 43 Blessed is that servant, whom his lord when he cometh shall find so doing. 44 Of a truth I say unto you, that he will make him ruler over all that he hath. 45 But and if that servant say in his heart, My lord delayeth his coming; and shall begin to beat the menservants and maidens, and to eat and drink, and to be drunken; 46 The lord of that servant will come in a day when he looketh not for him, and at an hour when he is not aware, and will cut him in sunder, and will appoint him his portion with the unbelievers. 47 And that servant, which knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes. 48 But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more. 49 I am come to send fire on the earth; and what will I, if it be already kindled?
If any saved believer runs that race to obtain salvation, then that is a work that denies Him as being their Saviour, and not having entered into that rest provided by Jesus Christ.
Hebrews 4:1Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it. 2 For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it. 3 For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.....
