The Bible teaches that the Old Testament's law and covenant are fulfilled and superseded by Jesus Christ in the New Testament, who establishes a better covenant of grace and internal transformation.
The Old Testament establishes God's covenant relationship with Israel through law and prophecy, culminating in Isaiah's vision of a suffering servant who bears humanity's sin. The New Testament reveals that Jesus Christ—the eternal Word who became flesh—fulfills the Old Testament law and prophets, replacing the old covenant's sacrificial system with his once-for-all offering that justifies believers through faith and inaugurates an internal, grace-based covenant written on human hearts.
Genesis 1:1
In the beginning, God created the heavens and the earth.
Exodus 19:5-6
Now therefore, if you will indeed obey my voice, and keep my covenant, then you shall be my own possession from among all peoples; for all the earth is mine; and you shall be to me a kingdom of priests, and a holy nation.’ These are the words which you shall speak to the children of Israel.”
Isaiah 53:1-12
Who has believed our message? To whom has the arm of Yahweh been revealed? For he grew up before him as a tender plant, and as a root out of dry ground. He has no good looks or majesty. When we see him, there is no beauty that we should desire him. He was despised, and rejected by men; a man of suffering, and acquainted with disease. He was despised as one from whom men hide their face; and we didn’t respect him. Surely he has borne our sickness, and carried our suffering; yet we considered him plagued, struck by God, and afflicted. But he was pierced for our transgressions. He was crushed for our iniquities. The punishment that brought our peace was on him; and by his wounds we are healed. All we like sheep have gone astray. Everyone has turned to his own way; and Yahweh has laid on him the iniquity of us all. He was oppressed, yet when he was afflicted he didn’t open his mouth. As a lamb that is led to the slaughter, and as a sheep that before its shearers is silent, so he didn’t open his mouth. He was taken away by oppression and judgment; and as for his generation, who considered that he was cut off out of the land of the living and stricken for the disobedience of my people? They made his grave with the wicked, and with a rich man in his death; although he had done no violence, nor was any deceit in his mouth. Yet it pleased Yahweh to bruise him. He has caused him to suffer. When you make his soul an offering for sin, he will see his offspring. He will prolong his days, and Yahweh’s pleasure will prosper in his hand. After the suffering of his soul, he will see the light and be satisfied. My righteous servant will justify many by the knowledge of himself; and he will bear their iniquities. Therefore will I give him a portion with the great, and he will divide the plunder with the strong; because he poured out his soul to death, and was counted with the transgressors; yet he bore the sin of many, and made intercession for the transgressors.
Jeremiah 31:31-34
Behold, the days come,” says Yahweh, “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 covenant of mine they broke, although I was a husband to them,” says Yahweh. But this is the covenant that I will make with the house of Israel after those days,” says Yahweh: I will put my law in their inward parts, and I will write it in their heart. I will be their God, and they shall be my people. They will no longer each teach his neighbor, and every man teach his brother, saying, ‘Know Yahweh;’ for they will all know me, from their least to their greatest,” says Yahweh: “for I will forgive their iniquity, and I will remember their sin no more.”
Matthew 5:17
Don’t think that I came to destroy the law or the prophets. I didn’t come to destroy, but to fulfill.
Luke 24:44-47
He said to them, “This is what I told you, while I was still with you, that all things which are written in the law of Moses, the prophets, and the psalms, concerning me must be fulfilled.” Then he opened their minds, that they might understand the Scriptures. He said to them, “Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day, and that repentance and remission of sins should be preached in his name to all the nations, beginning at Jerusalem.
John 1:1-14
In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made through him. Without him was not anything made that has been made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness hasn’t overcome it. There came a man, sent from God, whose name was John. The same came as a witness, that he might testify about the light, that all might believe through him. He was not the light, but was sent that he might testify about the light. The true light that enlightens everyone was coming into the world. He was in the world, and the world was made through him, and the world didn’t recognize him. He came to his own, and those who were his own didn’t receive him. But as many as received him, to them he gave the right to become God’s children, to those who believe in his name: who were born not of blood, nor of the will of the flesh, nor of the will of man, but of God. The Word became flesh, and lived among us. We saw his glory, such glory as of the one and only Son of the Father, full of grace and truth.
Romans 3:21-26
But now apart from the law, a righteousness of God has been revealed, being testified by the law and the prophets; even the righteousness of God through faith in Jesus Christ to all and on all those who believe. For there is no distinction, for all have sinned, and fall short of the glory of God; being justified freely by his grace through the redemption that is in Christ Jesus; whom God sent to be an atoning sacrifice, through faith in his blood, for a demonstration of his righteousness through the passing over of prior sins, in God’s forbearance; to demonstrate his righteousness at this present time; that he might himself be just, and the justifier of him who has faith in Jesus.
Hebrews 8:6-13
But now he has obtained a more excellent ministry, by so much as he is also the mediator of a better covenant, which on better promises has been given as law. For if that first covenant had been faultless, then no place would have been sought for a second. For finding fault with them, he said, “Behold, the days come”, says 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 lead them out of the land of Egypt; for they didn’t continue in my covenant, and I disregarded them,” says the Lord. For this is the covenant that I will make with the house of Israel. After those days,” says the Lord; “I will put my laws into their mind, I will also write them on their heart. I will be their God, and they will be my people. They will not teach every man his fellow citizen, and every man his brother, saying, ‘Know the Lord,’ for all will know me, from their least to their greatest. For I will be merciful to their unrighteousness. I will remember their sins and lawless deeds no more.” In that he says, “A new covenant”, he has made the first old. But that which is becoming old and grows aged is near to vanishing away.
Hebrews 10:1-18
For the law, having a shadow of the good to come, not the very image of the things, can never with the same sacrifices year by year, which they offer continually, make perfect those who draw near. Or else wouldn’t they have ceased to be offered, because the worshipers, having been once cleansed, would have had no more consciousness of sins? But in those sacrifices there is a yearly reminder of sins. For it is impossible that the blood of bulls and goats should take away sins. Therefore when he comes into the world, he says, “Sacrifice and offering you didn’t desire, but you prepared a body for me. You had no pleasure in whole burnt offerings and sacrifices for sin. Then I said, ‘Behold, I have come (in the scroll of the book it is written of me) to do your will, O God.’” Previously saying, “Sacrifices and offerings and whole burnt offerings and sacrifices for sin you didn’t desire, neither had pleasure in them” (those which are offered according to the law), then he has said, “Behold, I have come to do your will.” He takes away the first, that he may establish the second, by which will we have been sanctified through the offering of the body of Jesus Christ once for all. Every priest indeed stands day by day serving and often offering the same sacrifices, which can never take away sins, but he, when he had offered one sacrifice for sins forever, sat down on the right hand of God; from that time waiting until his enemies are made the footstool of his feet. For by one offering he has perfected forever those who are being sanctified. The Holy Spirit also testifies to us, for after saying, This is the covenant that I will make with them: ‘After those days,’ says the Lord, ‘I will put my laws on their heart, I will also write them on their mind;’” then he says, “I will remember their sins and their iniquities no more.” Now where remission of these is, there is no more offering for sin.
