Heb 10:9 Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second. Many today are deluded into believing that there is a future time coming, the millennium they call it, when God restores and earthly jewish nation that brings back the OC system of worship, all this because they canalize OT Prophecies, especially in Ezk, but this is a most grave error, and only those whom Christ died for shall escape this deadly deception. The Truth of the matter is, since the oblation of Christ, there is no more need for such sacrifices and offerings, and His Offering has once and for all has done away with them, for God has now no pleasure in them, except for that temporal purpose that led up to Christ. In this regards look at Heb 7:18-19 18 For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. 19 For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God. Heb 9:6-10 6 Now when these things were thus ordained, the priests went always into the first tabernacle, accomplishing the service of God. 7 But into the second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people: 8 The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing: 9 Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience; 10 Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation. For the sake of space please read Heb 10:1-9 to clarify this point ! Now that Christ has come and offered up Himself under the New Covenant Matt 26:28 28 For this is my blood of the new testament, which is shed for many for the remission of sins. Its no more time to revert back to that which God has taken away, but now and ever since, God has been about establishing the Second, that is the New Covenant and its attending blessings to a specific People Jer 31:31-34; Heb 8:6-12. The word establish Heb 10:9 is the greek word histēmi and means: to cause or make to stand, to place, put, set to make firm, fix establish Now for men to teach a reverting back, is very dishonoring to God and to Christ, the Mediator of the New Covenant. It would be insane for God to go back to a system that made nothing perfect. Also it would make no sense at all that such reverting would be commemorating of the Lord Jesus Christ and His offering, for he gave instruction for that here 1 Cor 11:23-26 23 For I have received of the Lord that which also I delivered unto you, that the Lord Jesus the same night in which he was betrayed took bread: 24 And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. 25 After the same manner also he took the cup, when he had supped, saying, this cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. 26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
