Couldn't be any clearer than that. IT IS FINISHED. He is SITTING on the right hand of God. There is no ongoing sacrifice.
"By the which will we ARE sanctified through the offering of the body of Jesus Christ ONCE FOR ALL...But this man, after he had offered ONE SACRIFICE FOR SINS FOREVER, SAT DOWN on the right hand of God..for by ONE OFFERING he hath perfected FOREVER them that are sanctified." Heb. 10:10,12,14.
Yes He is seated, in heaven, but as you can see below, He is also performing His priestly service to the Father. He is a priest in the order of Melchizedek, who offered bread and wine. Jesus at the last supper, offered himself as the unblemished Lamb of God. His offering to the Father started in the upper room, where He initiated the New Covenant in His Blood. That same offering continued through His passion and death and still continues in heaven, without end.
Hebrews 8
New King James Version (NKJV)
The New Priestly Service
8 Now this is the main point of the things we are saying: We have such a High Priest, who is seated at the right hand of the throne of the Majesty in the heavens, 2 a Minister of the sanctuary and of the true tabernacle which the Lord erected, and not man.
3 For every high priest is appointed to offer both gifts and sacrifices. Therefore it is necessary that this One also have something to offer. 4 For if He were on earth, He would not be a priest, since there are priests who offer the gifts according to the law; 5 who serve the copy and shadow of the heavenly things, as Moses was divinely instructed when he was about to make the tabernacle. For He said, See that you make all things according to the pattern shown you on the mountain.[a] 6 But now He has obtained a more excellent ministry, inasmuch as He is also Mediator of a better covenant, which was established on better promises.
STOP ISOLATING SINGLE " ONE HIT WONDER" VERSES ONLY. HERE ARE OTHERS. READ Scriptures in Balance beginning, middle And end:
Matt 21: 28 But what think ye? A certain man had two sons; and he came to the first, and said, Son, go work to day in my vineyard.
29 He answered and said, I will not: but afterward he repented, and went. 30 And he came to the second, and said likewise. And he answered and said, I go, sir: and went not.
31 Whether of them twain did the will of his father? They say unto him, The first. Jesus saith unto them, Verily I say unto you, That the publicans and the harlots go into the kingdom of God before you
Thus, a single one-time declaration of obdeince does not guarantee salvation!
Heb 3:14 - We have come to Share( acting accordingly) in Christ if we hold firmly till the END the confidence we had at first.
John 12:36 - Put your trust in the light while you have it, so that you may BECOME sons of light.
1 CO 9:24 - Do you not know that in a race all the runners run, but only one gets the prize? RUN in such a way as to get the prize.
2 Titus 4:7 - I have fought the good fight, I have FINISHED THE RACE, I have kept the faith.
Heb 12:1 - Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles, and LET US RUN with perseverance the race marked out for us.
Phil 3:14 - I PRESS ON toward the goal to win the prize
REV 2:26 - To him who overcomes and does my will to the end, I will give authority over the nations
REV 3:21 - To him who overcomes, I will give the right to sit with me on my throne.
Revelation 2
To the Church in Ephesus
1 To the angel[a] of the church in Ephesus write:........ 4 Yet I hold this against you: You have forsaken the love you had at first. 5 Consider how far you have fallen! Repent and do the things you did at first. If you Do Not Repent, I will come to you and REMOVE your Lampstand from its place. 6 But you have this in your favor: You hate the practices of the Nicolaitans, which I also hate.
