Yes, the old Covenant expired when Jesus died.
But as He was dead for 3 days, it was impossible for Him to make the new Covenant then and it awaits the time when His faithful followers are gathered into the holy Land:
Isaiah 59:20-21 The Lord will come as a Redeemer to Zion and to those descended from Jacob who repent of their rebellion. This is the Covenant I will make with them: My Spirit will abide with them thru all the following generations.
Jeremiah 32:37-40 I shall gather My people from all the lands where they now live......I will make an everlasting Covenant with them, it will be a joy for Me to do them good.
Ezekiel 37:26 [After the Spiritual regeneration and the rejoining of the tribes] I shall make an everlasting Covenant with them, for their peace and prosperity and their numbers will greatly increase. I will put My Sanctuary in their midst, where it will remain for all time.
THESE prophesies prove the New Covenant is not yet.
Your quotes in #2483, are to do with our salvation, NOT the NC.
Until people here acknowledge the truth of when the NC will actually be made between Jesus and His people and how our destiny is to live in all of the holy Land, I just have to realize that the many scriptures that say how people will be blinded and their understanding blocked, still applies today.
Not so! Quite the opposite. You are letting your faulty beliefs explain away clear and unambiguous Scripture.
Christ ushered in an everlasting covenant through His sinless life, His atoning death, His victorious resurrection and His glorious heavenly mediatory work in glory. Scripture shows that the old temporal covenant was not only removed but was replaced with a new eternal covenant. We are not living in a spiritual void now, having to bear our own guilt and shame, as you would suggest. Christ paid the cost in full and applied the benefits of the same to us through the regenerating power of His Spirit.
Jeremiah first prophesied the coming and character of the new covenant, in Jeremiah 31:31-33, saying,
“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: 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: 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.”
Jeremiah continues in the next verse, saying,
“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” (Jeremiah 31:34).
The writer of the Hebrews addresses this passage directly, quoting it and applying it to Christ and His atoning work at Calvary. The animal sacrifices were done away forever. Hebrews 10:4-12 explains,
“For it is not possible that the blood of bulls and of goats should take away sins. Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me: In burnt offerings and sacrifices for sin thou hast had no pleasure. Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God. Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law; Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.”
The old covenant with its unsatisfactory imperfect animal sacrifices have now been replaced by the new covenant with its one individual all-sufficient perfect eternal sacrifice. Paul outlines an important New Testament principle in 1 Corinthians 15:46, which is evident in every aspect of God’s plan and purpose with mankind,
“that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.”
Hebrews 7:19-22 declares,
“For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God. And inasmuch as not without an oath he was made priest: (For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec) By so much was Jesus made a surety of a better testament.”
Hebrews 8:6-8 says, of Christ and His vicarious atonement,
“now hath He obtained a more excellent ministry (than those exercised by the Old Testament priests with their imperfect sacrifices),
by how much also He is the mediator of a better covenant, which was established upon better promises. For if that first covenant had been faultless, then should no place have been sought for the second. For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant.”
The writer of the Hebrews then quotes Jeremiah 31, thus demonstrating its actual fulfilment.
Hebrews 8:13 continues,
“In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away”
Not long after this epistle was written, the temple with its inbuilt sacrifices was finally destroyed. With the destruction of the temple of few years later in AD 70, the temple sacrifices vanished forever.
The atonement is current, active and efficacious!
Romans 3:24-25:
“Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be a propitiation (hilasmos or atonement) through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God.”
1 John 2:1-2: “My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: And he is the propitiation (hilasterion or atonement) for our sins: and not for ours only, but also for the sins of the whole world.”
1 John 4:9-10: “In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him. Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation (hilasterion or atonement) for our sins.”
The word propitiation here in 1 John 2:1-2 and 1 John 4:9-10 is the Greek word hilasmos (Strong’s 2434) meaning atonement, i.e. (concretely) an expiator. In Romans 3:24-25 (Strong’s 2434) it is hilasterion, which refers to an expiatory (place or thing), i.e. (concretely) an atoning victim, or (specially) the lid of the Ark (in the Temple) – the mercy seat.
