The Old Testament and the New Testament: Understanding Their Relationship Without Confusion

One of the oldest and most frequent debates in Christianity is the relationship between the Old Testament and the New Testament. Some believers claim the Old Testament is no longer relevant because Christians live under grace. Others insist that Christians must continue observing every law given to Israel. These differing views have caused confusion in churches, Bible studies, and personal Christian growth.

The truth is that the Bible does not present the Old and New Testaments as enemies. Rather, they are two parts of one divine revelation. The New Testament does not replace God's truth found in the Old Testament; instead, it fulfills, explains, and completes it through Jesus Christ.

What Are the Old and New Testaments?

The word "testament" means covenant or agreement.

The Old Testament records God's covenant with Israel, beginning with creation and continuing through the Law given to Moses, the history of Israel, the writings of wisdom, and the messages of the prophets.

The New Testament records the coming of Jesus Christ, His death and resurrection, the birth of the Church, and God's New Covenant established through Christ.

Both reveal the same God. His character does not change.

> Malachi 3:6 (NKJV)

"For I am the LORD, I do not change..."

Why Did God Give the Old Testament?

The Old Testament serves several important purposes.

1. It Reveals God's Character

Before understanding God's grace, we must understand His holiness.

The Old Testament teaches that God is:

Holy

Just

Merciful

Faithful

Loving

Righteous

For example:

> Exodus 34:6–7 (NKJV)

"The LORD, the LORD God, merciful and gracious, longsuffering, and abounding in goodness and truth..."

Without the Old Testament, many people would misunderstand who God truly is.

2. It Reveals Humanity's Sinfulness

The Law was never given as a way for people to earn salvation.

Instead, it exposed sin.

Paul explains:

> Romans 3:20 (NKJV)

"...for by the law is the knowledge of sin."

The Law acts like a mirror. A mirror shows dirt on your face, but it cannot wash your face. In the same way, the Law reveals sin but cannot remove it.

3. It Points to Jesus Christ

The Old Testament contains hundreds of prophecies, symbols, and shadows pointing to Christ.

Jesus Himself said:

> John 5:39 (NKJV)

"You search the Scriptures... these are they which testify of Me."

Examples include:

The Passover lamb (Exodus 12) pointing to Christ, the Lamb of God.

The bronze serpent (Numbers 21) pointing to Christ being lifted up on the cross.

The sacrifices pointing to Christ's perfect sacrifice.

The High Priest pointing to Jesus, our eternal High Priest.

Why Was the New Testament Necessary?

The Old Covenant revealed humanity's need for a Savior but could not permanently remove sin.

Animal sacrifices had to be offered repeatedly.

> Hebrews 10:4 (NKJV)

"For it is not possible that the blood of bulls and goats could take away sins."

Jesus became the perfect sacrifice.

> John 1:29 (NKJV)

"Behold! The Lamb of God who takes away the sin of the world!"

His sacrifice was complete.

> Hebrews 10:12 (NKJV)

"But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God."

Did Jesus Abolish the Old Testament?

One of the most misunderstood verses is Matthew 5:17.

Jesus said:

> Matthew 5:17 (NKJV)

"Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill."

To fulfill means to bring to completion.

Jesus fulfilled:

The prophecies.

The sacrifices.

The priesthood.

The ceremonial system.

The righteous requirements of the Law.

He did not destroy God's Word. He accomplished what it pointed toward.

Are Christians Required to Keep the Law of Moses?

This question has divided Christians for centuries.

The New Testament teaches that believers are not justified by keeping the Law, but by faith in Jesus Christ.

> Galatians 2:16 (NKJV)

"...a man is not justified by the works of the law but by faith in Jesus Christ..."

The ceremonial laws of Israel—such as animal sacrifices, temple rituals, dietary laws, and ceremonial cleanliness—were fulfilled in Christ.

However, God's moral standards are still reflected in the New Testament. Believers are still called to reject sin, love God, and love their neighbors.

Why Should Christians Still Read the Old Testament?

Some Christians neglect the Old Testament, but doing so causes them to miss much of God's revelation.

Paul wrote:

> 2 Timothy 3:16–17 (NKJV)

"All Scripture is given by inspiration of God, and is profitable..."

The Old Testament helps us understand:

Creation.

The fall of humanity.

God's promises.

The origin of sin.

The history of redemption.

The coming Messiah.

God's faithfulness throughout history.

Without it, many New Testament passages lose their deeper meaning.

How the Old Testament and New Testament Work Together

The relationship between the two Testaments is one of promise and fulfillment.

The Old Testament promises a Redeemer; the New Testament reveals Him.

The Old Testament gives shadows; the New Testament reveals the reality.

The Old Testament predicts; the New Testament fulfills.

The Old Testament prepares the way; the New Testament completes God's redemptive plan in Christ.

This unity demonstrates that the Bible tells one continuous story centered on Jesus.

Common Mistakes in This Debate

Many misunderstandings arise from extreme positions.

Some reject the Old Testament entirely, ignoring its value for teaching, correction, and understanding God's character.

Others attempt to place believers back under every requirement of the Mosaic Law, overlooking the fulfillment of the Law in Christ and the teaching of the New Testament regarding the New Covenant.

A balanced approach recognizes that the Old Testament remains God's inspired Word while understanding that Christians live under the New Covenant established by Jesus Christ.

Practical Lessons for Believers

1. Read both Testaments regularly, because both reveal God's truth.

2. Interpret the Old Testament in light of Christ and the New Testament.

3. Appreciate God's unchanging character revealed throughout Scripture.

4. Remember that salvation has always been by God's grace through faith, with Jesus Christ as the fulfillment of God's redemptive plan.

5. Let the Old Testament deepen your understanding of the New Testament, and let the New Testament help you understand the Old.

Conclusion

The Old Testament and the New Testament are not in conflict. They are complementary parts of God's inspired revelation. The Old Testament lays the foundation, and the New Testament builds upon it by revealing Jesus Christ as the promised Messiah and Savior.

As believers, we should treasure both Testaments. Together they reveal God's holiness, humanity's need for redemption, and the glorious gospel of Jesus Christ. Studying them side by side strengthens our faith, deepens our understanding of Scripture, and equips us to live faithfully under the New Covenant while appreciating the rich heritage of God's dealings with His people.

> Luke 24:27 (NKJV)

"And beginning at Moses and all the Prophets, He expounded to them in all the Scriptures the things concerning Himself."

Everything in Scripture ultimately points to Jesus Christ, who is the center of God's plan of salvation.
