The question of whether Christians are still required to follow the Old Testament Law continues to raise important conversations. It is not only a theological issue. It shapes how people understand the entire story of Scripture, how they see God’s character and how they live out their faith in everyday life.
When reading the Old Testament, it is easy to notice the detailed system of commands, rituals and instructions that defined the life of Israel. These laws were not random. They shaped identity, worship and community in a very specific context.
However, the arrival of Jesus introduces something that changes how these laws are understood. In teachings recorded in the Gospel of Matthew and other New Testament writings the focus shifts toward fullfillment rather than simple continuation.
Purpose of the Old Testament Law
The Old Testament Law, also known as the Mosaic Law, revealed God’s holiness while exposing the reality of human sin. It shaped Israel into a set-apart nation and pointed forward to the coming Messiah. Romans 3:20 explains that the Law helps humanity recognize sin. It served as a mirror that revealed the need for a Savior rather than a pathway to salvation.
Key Purposes of the Law
- It revealed God’s holiness.
- It exposed human sinfulness.
- It shaped Israel as a distinct people.
- It pointed forward to the Messiah.
Jesus and the Fullfillment of the Law
Jesus declared in Matthew 5:17 that He came to fullfill the Law rather than abolish it. His life and ministry brought the Law to its intended completion. Through His perfect obedience, His once-for-all sacrifice, and the fullfillment of every prophetic promise, Jesus revealed the true depth and meaning behind God’s commands. Hebrews 10:1–10 teaches that the Law served as a shadow pointing forward to Christ, who brought its purpose to full reality.
How Jesus Fulfilled the Law
- Perfect obedience
- Completion of the sacrificial system
- Fullfillment of prophetic promises
- Revelation of the deeper meaning behind God’s commands

Under Law or Under Grace
Romans 6:14 teaches that believers are not under the Law but under grace. This does not erase God’s moral standards. Instead, it reshapes the relationship between God and His people. The book of Galatians explains that Christians are no longer bound to the rituals, ceremonies and regulations of the Old Covenant. Instead, they live through the empowering presence of the Holy Spirit.
Key Truths About Grace
- The Holy Spirit empowers Christian living
- Believers are under grace, not the Law
- God’s moral standards remain unchanged
- Old Covenant rituals are no longer binding
Which Old Testament Laws Apply Today?
Christians are not obligated to keep Israel’s ceremonial or civil laws. These included:
- Animal sacrifices
- Temple rituals
- Dietary regulations
- Israelite national laws
- Festival requirements
These were fulfilled entirely in Christ.
However, the moral law reflects God’s unchanging character. Principles such as honesty, purity, justice and love continue to guide Christian living. Believers obey these truths not to earn righteousness, but because God has already granted righteousness through Christ.
The Law’s Role in Grace-Based Living
Grace does not weaken obedience. Grace strengthens and empowers it. Under the New Covenant, God writes His truth on the hearts of believers, as Jeremiah 31:33 explains. Christians now obey from a changed inner life rather than external obligation. Their obedience grows from love, gratitude, spiritual renewal and the active work of the Holy Spirit.
How Grace Shapes Obedience
- Love
- Gratitude
- Spiritual transformation
- The power of the Holy Spirit
Salvation and the Old Testament Law
Scripture teaches that salvation does not come through law-keeping. Ephesians 2:8–9 states that salvation is a gift of grace received through faith, not the result of works, so that no one can boast. Paul warns in Galatians 2:21 that if righteousness could come through the Law, then the death of Christ would lose its meaning and purpose. The cross demonstrates that human effort cannot save or make a person righteous before God, no matter how sincere or disciplined those efforts may be. Instead the Law reveals human sin and the need for a Savior. Only the grace of God can bring redemption, freely given and received through faith.
Key Truths About Salvation
- Salvation does not come through the Law
- It is received by grace through faith
- Human righteousness is insufficient
- The cross confirms that only grace can save
Law and Grace in the New Covenant
The Law and Grace do not oppose each other. They serve different purposes, working together within God’s plan rather than contradicting one another:
The Law reveals humanity’s need by showing God’s standard of holiness and making people aware of their inability to fully meet it, highlighting the gap between human effort and divine perfection. Grace provides God’s solution through the gift of salvation, offering what the Law could not accomplish on its own by freely giving righteousness through faith.
The Law exposes sin by defining it clearly and bringing conviction to the heart, making sin recognizable rather than hidden or excused. Grace offers forgiveness and transformation, not only removing guilt but also enabling a changed life through God’s power and ongoing work within a believer.
God’s character remains consistent across both covenants, unchanging in holiness, justice and love, but His method of relationship has transitioned from Law to grace through Jesus Christ, fulfilling what the Law ultimately pointed toward and making a personal relationship with God possible.
Jesus, Love and the Law of Christ
Jesus summarized God’s heart for obedience through love. John 13:34 teaches believers to love as Christ loved. Paul refers to this as the Law of Christ in Galatians 6:2.
Christian obedience is now shaped by love, not ritual or legal requirement. The Holy Spirit empowers believers to live with Christlike character.
Practical Ways to Honour God Through Grace
Christians honour God’s Law through a life shaped by the Holy Spirit. Instead of relying on external rules, believers allow Scripture to guide their thoughts, attitudes and decisions. They pursue holiness from a heart filled with love, extend grace to others and walk in constant gratitude for the finished work of Christ. Grace strengthens holiness far more effectively than law-keeping ever could.
Ways to Honor God Through Grace
- Walking daily with the Holy Spirit
- Allowing Scripture to shape attitudes and choices
- Pursuing holiness from a place of love
- Giving grace to others
- Practicing gratitude for Christ’s finished work
Law’s Lasting Value Through the Lens of Grace
The Old Testament Law still carries deep value because it reveals God’s holiness, exposes humanity’s need and directs attention toward Jesus Christ. Yet believers now live under the New Covenant, where grace guides the heart, the Holy Spirit empowers daily life and transformation begins from within. The Law points toward Christ, and grace flows from Him. Through His work, Christians live in a way that honours God with sincerity, devotion and joy.

Frequently Asked Questions
Do the Law and Grace contradict each other?
No, they do not contradict each other. The Law and Grace serve different but complementary purposes within God’s plan. The Law reveals God’s standard and exposes human need, while Grace provides the solution through forgiveness and new life in Christ.
If salvation is by grace, what is the purpose of the Law?
The Law helps people recognize sin and understand their need for a Savior. It acts as a guide that points to God’s holiness and shows why grace is necessary, rather than being a means to earn salvation.
Can a person be saved by keeping the Law?
Scripture teaches that no one can be saved by keeping the Law perfectly. Human effort falls short, which is why salvation is offered as a gift of grace through faith, not as a reward for works.
Does grace mean the Law is no longer important?
Grace does not make the Law meaningless. Instead, it fulfills its purpose. The moral truths reflected in the Law still reveal God’s character but believers relate to God through grace rather than through strict law-keeping.
Has God’s character changed from the Old Testament to the New Testament?
No, God’s character remains the same—holy, just and loving. What has changed is the way He relates to humanity, moving from the framework of the Law to the fullfillment of that Law through Jesus Christ and the gift of grace.
