And with all those beautiful verses you quoted, you have yet shown any relevance of the gospel to Daniel 9 or to the new covenant!
The New Covenant is to the Jew! Let me remind you again of what GOD said:
31 Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:
32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord:
33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least of them unto the greatest of them, saith the Lord: for I will forgive their iniquity, and I will remember their sin no more.
35 Thus saith the Lord, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The Lord of hosts is his name:
36 If those ordinances depart from before me, saith the Lord, then the seed of Israel also shall cease from being a nation before me for ever.
If anything, when the new covenant is fully established- there will be no need for the gospel to be preached! verses33 and 34 show that.
But there is also this:
25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
27 For this is my covenant unto them, when I shall take away their sins.
28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the father's sakes.
29 For the gifts and calling of God are without repentance.
You forget that what has been happening since Pentecost was a mystery in the OT! Israel would be blinded in part (only some of Israel will see) UNTYIL UNTIL UNTIL the full number of teh gentiles are brought in ! Then what happens? The blinded ISrael will see and get saved! And this is according to the New Covenant God made with Israel on His own! The Old or Mosaic covenant was made with both God and Israel as partners. The New covenant is made by God alone! that is why the old was conditional but the new is unconditional!
Also 2 Cor. 3:
13 And not as Moses, which put a veil over his face, that the children of Israel could not stedfastly look to the end of that which is abolished:
14 But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.
15 But even unto this day, when Moses is read, the vail is upon their heart.
16 Nevertheless when it shall turn to the Lord, the vail shall be taken away.
one word is very key---in verse 16 "WHEN" not if!
