No one is arguing that Jesus's death, shed blood, was the atonement for sins under the new covenant. Atonement for sins finished when Jesus died.
But you cannot sever Jesus rising from the dead on the third day from the new covenant. The new covenant was completed when Jesus rose from the dead on the third day.
The issue at hand is what is meant by "it" is finished. The "it" is the atonement for sins. Not the completion of the new covenant.
The speaker in the video is New-Covenant-Theology. I put the dashes in to distinguish it a a man-made movement. As is Covenant-Theology. And Dispensationalism-Theology.
Covenant-Theology and New-Covenant-Theology don't recognize Jesus being anointed by the woman in Bethany, as Jesus being anointed for his burial. And instead revert back to Jesus being baptized by John in the wilderness 3 years plus earlier... in their interpretation of Daniel 9.
And the speaker in the video did not mention that on the cross was the sign - Jesus of Nazerth, King of the Jews - and its significance.
If your argument was correct, Jeremiah 31:31-34, and Hebrews 8:6-13, and Hebrews 10:16-18, would have nothing to do with the New Covenant, because His resurrection is not mentioned in those passages.
The same is true of the passage below.
You are attempting to climb a straight, smooth, vertical cliff face, without any equipment.
Heb 9:15 And for this reason
He is the Mediator of the new covenant, by means of death, for the redemption of the transgressions under the first covenant, that those who are called may receive the promise of the eternal inheritance.
Heb 9:16 For where there is a testament, there must also of necessity be the death of the testator.
Heb 9:17 For a testament is in force after men are dead, since it has no power at all while the testator lives.
Heb 9:18
Therefore not even the first covenant was dedicated without blood.
Heb 9:19 For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and goats, with water, scarlet wool, and hyssop, and sprinkled both the book itself and all the people,
Heb 9:20 saying, "THIS IS THE BLOOD OF THE COVENANT WHICH GOD HAS COMMANDED YOU."
Heb 9:21 Then likewise he sprinkled with blood both the tabernacle and all the vessels of the ministry.
Heb_9:22 And according to the law almost all things are purified with blood,
and without shedding of blood there is no remission.
Jer 31:34 No more shall every man teach his neighbor, and every man his brother, saying, 'Know the LORD,' for they all shall know Me, from the least of them to the greatest of them, says the LORD. For I will forgive their iniquity, and their sin I will remember no more."
