Well, circumcision was a ”seal” (covenant) for those under the old covenant.
Romans 4:11
And he received the sign of circumcision, a
SEAL of the righteousness of the faith which he had yet being uncircumcised: that he might be the father of all them that believe, though they be not circumcised; that righteousness might be imputed unto them also
This seal WAS broken and guaranteed nothing when those who were circumcised broke the covenant and were cut off from the people of God.
Romans 2:25-27
25 For circumcision verily profiteth, IF thou keep the law:
but IF thou be a breaker of the law, thy circumcision is made uncircumcision. 26 Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision? 27 And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law?
As you can see, this seal was conditioned on continued faith and obedience. The Holy Spirit marks us as God’s children of the new covenant but if we abandon the faith, and/or live in disobedience then the Spirit of God no longer remains in us and we are no longer sealed. Circumcised (sealed) jews were broken off through unbelief.
For what are the conditions of receiving the Holy Spirit?
The Bible says the Spirit is given to those who obey Him and or who keep His Commandments.
Acts 5:32
And we are his witnesses of these things; and so is also
the Holy Ghost, whom God hath given to them that obey him.
John 14:15-16
15
If ye love me, keep my commandments.16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever
Romans 8:9-10
9 But ye are not in the flesh, but in the Spirit, IF so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. 10 And IF Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
God speaks of the Israelites who ”grieved” His Holy Spirit in their rebellion. These Jews were cut off from the promise of entering God’s rest and they became God’s enemies.
Isaiah 63:10
But they rebelled, and vexed his holy Spirit:
THEREFORE he was turned to be their enemy, and he fought against them. —
Isaiah 63:14
As a beast goeth down into the valley, the Spirit of the LORD caused him to rest: so didst thou lead thy people, to make thyself a glorious name.
In the NT the ”rest” is the eternal rest that all believers will attain. The book of Hebrews continually speak of the promise of eternal rest, in combination with WARNINGS to believers not to miss out on this promised rest through hardening their hearts in unbelief, just as the Israelites did who rebelled against God during the Exodus.
Hebrews 3:6-19
3 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. 7 Wherefore (as the Holy Ghost saith, To day if ye will hear his voice, 8
Harden not your hearts, as in the provocation, in the day of temptation in the wilderness: 9 When your fathers tempted me, proved me, and saw my works forty years. 10 Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways. 11 So I sware in my wrath, They shall not enter into my rest.) 12 Take heed, 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 To day; lest any of you be hardened through the deceitfulness of sin. 14 For we are made partakers of Christ,if we hold the beginning of our confidence stedfast unto the end; 15 While it is said, To day if ye will hear his voice, harden not your hearts, as in the provocation. 16 For some, when they had heard, did provoke: howbeit not all that came out of Egypt by Moses. 17 But with whom was he grieved forty years? was it not with them that had sinned, whose carcases fell in the wilderness? 18 And to whom sware he that they should not enter into his rest, but to them that believed not? 19 So we see that they could not enter in because of unbelief.
Hebrews 4:1-11
1 Let 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. 4 For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works. 5 And in this place again, If they shall enter into my rest. 6 Seeing therefore it remaineth that some must enter therein, and they to whom it was first preachedentered not in because of unbelief: 7 Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts. 8 For if Jesus had given them rest, then would he not afterward have spoken of another day. 9 There remaineth therefore a rest to the people of God. 10 For he that is entered into his rest, he also hath ceased from his own works, as God did from his. 11 Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.
Hebrews 6:11-12
11 And we desire that every one of you do shew the same diligence to the full assurance of hope unto the end:
12 That ye be not slothful, but followers of them who through faith and patience inherit the promises.
Jude 1:5
I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.
