The Old Covenant and the New Covenant
The Bible itself speaks of an old covenant and a new covenant. Understanding that distinction helps you read commands, sacrifices, priesthood, ordinances, and promises without inventing different ways of salvation.

God promised a new covenant
Jeremiah 31:31 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:
Jeremiah 31:32 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:
Jeremiah 31:33 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.
Jeremiah 31:34 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.
The new covenant is not an idea imposed on the Bible. God promised it through Jeremiah. The writer of Hebrews later quotes this passage and explains the superiority of Christ's covenant.
Christ is the mediator of a better covenant
Hebrews 8:6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
Hebrews 8:13 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.
Hebrews 9:15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
The Mosaic covenant included a priesthood, sacrifices, sanctuary service, ceremonial requirements, and national laws given to Israel. Christ fulfilled what those shadows pointed toward and established the new covenant by His blood.
This means a Christian should not read Leviticus as though he must bring an animal sacrifice to a Levitical priest. Yet Leviticus remains inspired and profitable because it reveals God's holiness, the seriousness of sin, and patterns that prepare us to understand Christ.
Covenant difference is not a different gospel
Recognizing the old and new covenants is not the same thing as teaching multiple methods of salvation. Scripture never teaches that one group was justified by works while another was justified by faith. The covenantal responsibilities changed; the basis of justification did not become human merit.
This distinction protects you from two opposite errors: dragging obsolete covenant requirements into the church, or treating the Old Testament as useless. The right approach is to ask what covenantal setting a passage belongs to, what it reveals about God, how later Scripture uses it, and how its truth applies under the new covenant.
Covenant change is not a change in the way people are justified
The Bible really does distinguish the old covenant and the new covenant. Ignoring that distinction creates confusion about sacrifices, priesthood, circumcision, dietary commands, feast days, temple worship, and many commands given specifically within Israel's covenant life. But recognizing covenantal differences does not require teaching different plans of salvation.
The old covenant was made with Israel in connection with Sinai. It included a priesthood, sacrifices, ordinances, and national covenant responsibilities. The new covenant is established through Jesus Christ and His finished work. Hebrews explains the superiority of Christ's priesthood and sacrifice. The covenant administration changed; the principle of justification by faith did not suddenly appear in the New Testament.
Paul proves this by reaching before and during the law
In Romans 4, Paul uses Abraham from Genesis 15:6 and David from Psalm 32 to prove justification apart from works. Abraham lived before the law of Moses was given. David lived under that law. Paul deliberately reaches into both settings and gives the same conclusion: righteousness is counted by faith rather than earned by works.
Galatians 3 makes the point from another direction. The law, which came later, could not cancel God's earlier promise. The law exposed sin, governed covenant life, and pointed people toward the need for Christ; it was never a competing method by which sinners could earn eternal life.
Let the covenants clarify the text
When studying a command, ask whether it belongs to Israel's old-covenant national and ceremonial order, whether the New Testament repeats or transforms it, and what enduring truth it teaches. This prevents two opposite mistakes: dragging every Mosaic ordinance directly into church practice, or treating the Old Testament as though it has nothing to teach Christians.
Compare Scripture with Scripture
Scripture trail: Jeremiah 31:31 • Jeremiah 31:32 • Jeremiah 31:33 • Jeremiah 31:34 • Hebrews 8:6 • Hebrews 8:13 • Hebrews 9:15 • Genesis 15:6 • Nehemiah 8:8
Do not rush past the references. Open them, read the surrounding verses, and make the Bible carry the weight of the conclusion.
Think it through
- Who is speaking, who is being addressed, and what question or problem is the passage answering?
- What becomes clearer when the passages are compared instead of read as isolated slogans?
- Which conclusion is explicitly supported by the text, and which possible conclusion would go beyond what the text says?
Teach it back
Without looking at the lesson explanation, summarize The Old Covenant and the New Covenant in two or three sentences and support your explanation from Scripture. If you cannot explain it simply yet, return to the passages and work through them again.
Slow down and work the text
Reopen Jeremiah 31:31, Jeremiah 31:32, Jeremiah 31:33, Jeremiah 31:34. Read enough before and after each verse to see the setting. Do not settle for remembering a slogan when you can inspect the wording for yourself.
- Write the main claim of The Old Covenant and the New Covenant in one sentence.
- Underline or write down the exact words in the passages that support that claim.
- Compare at least two of the passages. What truth becomes clearer when they are read together?
- Ask what could be misunderstood if one phrase were isolated from its context.
- Write your observations before consulting notes or commentary, then state the conclusion the text itself supports.
- What does the passage state explicitly?
- What context or comparison keeps the interpretation accurate?
- What conclusion can you defend directly from the text?
The Bible distinguishes the old covenant from the new covenant. That affects priesthood, sacrifices, ordinances, and commands, but it does not create different ways of receiving eternal life.
