The Relation of Old Testament To the New Testament, and Dispensationalism
Matthew 5: 17 says "Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill."

In II Corinthians 3: 8 Paul calls the New Covenant, created by Jesus Christ, "...the ministration of the Spirit." He calls the Old Covenant "...the ministration of death in Ii Corinthians 3: 7 and ..."the ministration of condemnation in II Corinthians 3: 9.
And in II Corinthians 3: 6 Paul says that Christ ",,,hath made us able ministers of the new covenant; not of the letter, but of the spirit: for the letter killeth, but the Spirit giveth life."
In II Corinthians 5: 17 Paul says "Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new."
Just as anyone, regardless of his or her genetics, who is in Christ is a new creation (ktisis, creature or creation), so Christ made the New Covenant a new creation. In Romans 12: 2 Paul writes about being transformed by the renewing of your mind, referring to being born again (John 3: 1-6), and so Christ created the New Covenant as a transformation of the Old Covenant. This remaking of the Old Covenant was the remaking of Israel according to Jeremiah 18: 1-6. But in that remaking of Israel, Christ included the Gentiles (Hosea 2: 23) who became saved.
In Colossians 2: 16-16 Paul writes that "Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: 17. Which are a shadow of things to come; but the body is of Christ."
What Paul is saying is that the Old Covenant law involving circumcision, animal sacrifice, holy days, and the temple system, all of the flesh, and not of the ministration of the Spirit,was a mere shadow of the spiritual substance which was to come when Christ created the New Covenant.
Paul was to make an issue in the Jerusalem Church in Acts 15 over the teaching of men from Judea and the Pharisees in the Church (Acts 15: 1, 5) that Gentiles must be circumcised, a teaching that opposed the transformation of the Old Covenant physical emphasis to the New Covenant's spiritual nature in Christ and the Holy Spirit.
Paul says in I Corinthians 3: 16-17 and In I Corinthians 6: 19 that Christian believers are the temple of God and that the bodies of the believers are the temple of the Holy Spirit, a transformation of the temple system.
And, while there are a great many prophecies about the coming of the New Covenant and about Jesus Christ appearing, none of these Old Testament prophecies fulfilled in the New Testament involve the insistence of dispensationalists that a physical land promise to Israel is to be fulfilled in the future from now.
Instead, the Old Testament prophecies fulfilled in the New Testament are about spiritual things, not things of the flesh like circumcision, or the land.
For example, Isaiah 53 is a prophecy about Christ.
"But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed. 6. All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all." Isaiah 53: 5-6
Daniel 9: 24 is a prophecy about the work of redemption to be done in the New Covenant by Christ. "Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy."
Hosea 13: 14 predicts that Jesus Christ will defeat death itself. "I will ransom them from the power of the grave; I will redeem them from death: O death, I will be thy plagues; O grave, I will be thy destruction:"
Zechariah 9: 9 predicts that Christ will bring salvation. "Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ***, and upon a colt the foal of an ***."
Then, Malachi 3: 1 writes about Christ being the messenger of the New Covenant. "Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to this temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the LORD of hosts."
In Acts 2: 16-18 Peter refers to Joel 2: 28 - "And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:"
Peter is saying here that the appearing of the Holy Spirit in Acts 2 was a fulfillment of the prophesy of Joel 2: 28. The appearing of the Holy Spirit marked the beginning of he New Covenant.
The New Testament is silent about the land promises in the Old Testament to Israel. The New Testament statements which show specific fulfillments of Old testament prophecy about Jesus Christ and the New Covenant are all spiritual in nature, since the New Covenant is the "Ministration of the Spirit."
Yet dispensatonlism comes along in the 19th century and claims that Old Covenant Israel is an eternal people of God, while the Gentile Church is only a parenthesis between two dispensations of Old Covenant physical Israel, which Christ had transformed in the early First Century
