[Yosemitest]

Your reference to Hebrew 8:9-13 WILL HAPPEN, but it hasn't happened yet.
That WILL HAPPEN AFTER Jesus's second coming.
I think the only changes that are current now to the Covenant we have with god is explained in Bread and Wine Ceremony at Passover night.

Remember:

"For the time is come that JUDGMENT MUST BEGIN at the house of God:
and if it first begin at us,
what shall the end be of them that obey NOT the gospel of God?"

Remember:

"Beware of false prophets, which come to you in sheep's clothing,
but inwardly they are ravening wolves.
Ye shall know them by their fruits.
Do men gather grapes of thorns, or figs of thistles?
Even so every good tree bringeth forth good fruit;
but a corrupt tree bringeth forth evil fruit.
A good tree cannot bring forth evil fruit,
neither can a corrupt tree bring forth good fruit.
Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
Wherefore by their fruits ye shall know them.

NOT every one that saith unto me,
Lord, Lord, SHALL ENTER into the kingdom of heaven;
but HE THAT DOETH THE WILL OF MY FATHER which is in heaven.
Many will say to me in that day,
Lord, Lord, have we not prophesied in thy name?
and in thy name have cast out devils?
and in thy name done many wonderful works?
And then will I profess unto them,
I NEVER KNEW YOU: DEPART FROM ME, YE THAT WORK INIQUITY.
Therefore whosoever HEARETH these sayings of mine, and DOETH them,
I will liken him unto a wise man, which built his house upon a rock:
And the rain descended, and the floods came, and the winds blew, and beat upon that house;
and it fell not: for it was founded upon a rock.
And every one that HEARETH these sayings of mine, and DOETH THEM NOT,
shall be likened unto a foolish man, which built his house upon the sand:
And the rain descended, and the floods came, and the winds blew, and beat upon that house;
and it fell: and great was the fall of it.

And it came to pass, when Jesus had ended these sayings, the people were astonished at his doctrine:
For he taught them as one having authority,
and not as the scribes.

Think you,

that Jesus came to do away with the Law ?

God forbid !

He came to fulfill it.

[PapaNew]

No, the New Covenant was instituted at the Cross of Christ, or else you don't understand the gospel of the grace of the Lord Jesus Christ. We are now not under the law but under grace. (Rom 6:14).

I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. (Gal 1:6-8).

Paul twice repeats the curse on "another gospel" that is not gospel of grace of Christ (Gal. 1:6-9).

We are no longer under the curse of the law (Gal 3:13).
