Law

The English word “Law” in most Old Testament passages translates the Hebrew word torah (תּוֹרָה). In the New Testament, “Law” most often renders the Greek word nomos (νόμος).

Word	Language	Core Meaning
torah	Hebrew	Instruction, teaching, direction, guidance, statute, law
nomos	Greek	Law, principle, regulation, custom, a binding standard

Although torah can refer to legal commands, its semantic range is broader than mere legislation. It fundamentally means instruction from an authority, particularly God. Likewise, nomos denotes a recognised, binding standard that governs behaviour, either divine or societal.

The Law as God’s Instruction

Key Citations

Psalm 1:2 says, “But his delight is in the law of the LORD, and in His law he meditates day and night.”

This shows Law (torah) is not presented as a burden but a delightful source of divine guidance for the righteous. The verse equates torah with something to be pondered devotionally, not merely obeyed juridically.

Isaiah 2:3 says, “For the law will go forth from Zion and the word of the LORD from Jerusalem.”

Here torah is parallel to “the word of the LORD,” reinforcing that Law = God’s revealed instruction to His people and the nations.

The Law Given Through Moses

Joshua 1:8 says, “This book of the law shall not depart from your mouth, but you shall meditate on it day and night…”

The “book of the Law” refers specifically to Moses’ written torah, showing that a major biblical usage of “Law” is the Mosaic revelation, the foundation of Israel’s covenant life.

The Law as Covenant Standard

Exodus 24:12 says, “I will give you the tablets of stone, with the law and the commandment which I have written…”

Here “Law” refers to the divinely inscribed commands that form Israel’s covenant obligations. In biblical theology, the Law is not merely ethical guidance, it is the constitutional standard of the Old Covenant.

Categories of “Law” in Scripture

The Bible uses “Law” in several overlapping but distinguishable ways.

1.     The Pentateuch as a whole (Genesis–Deuteronomy). Luke 24:44 says, “...all things which are written about Me in the Law of Moses and the Prophets and the Psalms…”

2.     Specific commandments within the Mosaic Covenant. Deuteronomy 4:8 says,“...what great nation is there that has statutes and judgements as righteous as this whole law…”

3.     God’s instruction more generally (not always legal). Proverbs 6:23 says, “For the commandment is a lamp and the teaching (torah) is light…”

4.     A moral or spiritual principle. Romans 7:23 says “...I see a different law in the members of my body, waging war…” This is nomos used metaphorically to mean a governing principle, not the Mosaic code.

5.     The divine moral standard that reveals sin. Romans 3:20 says, “...for through the Law comes the knowledge of sin.”

The Law functions diagnostically, it exposes transgression.

The Law’s Purpose in God’s Plan

Reveals God’s Character

Psalm 19:7 says, “The law of the LORD is perfect, restoring the soul…”The Law reflects the perfection of God’s instruction, demonstrating His holiness and wisdom.

Defines Sin

1 John 3:4 says, “Everyone who practises sin also practises lawlessness…” Though “Law” is not used directly here, lawlessness (anomia) is the rejection of God’s nomos standard, proving that Law provides the boundary markers of righteousness vs sin.

Guards Israel Until Messiah

Galatians 3:24 says, “Therefore the Law has become our tutor to lead us to Christ…” Nomos is described as a custodian and tutor that preserves God’s people until Christ fulfils its purpose.

Christ and the Law

Matthew 5:17 says, “Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfil.” Christ did not nullify torah/nomos, He completed its intent, prophetic trajectory, and demands. The Law pointed forward to Him and finds its telos (goal fulfilment) in His person and work.

Romans 10:4 says, “For Christ is the end of the law for righteousness to everyone who believes.” “End” here means goal, culmination, fulfilment, not annihilation. Christ brings the Law’s redemptive purpose to completion.

The Law in the Life of the Believer

Believers are not justified by the Mosaic Law, yet God’s moral instruction still guides Christian obedience. Romans 8:4 says, “...so that the requirement of the Law might be fulfilled in us, who do not walk according to the flesh but according to the Spirit.”

The righteous requirement of the Law is now lived out by the Spirit’s enabling, not by covenantal obligation to the Law of Moses.

Psalm 119:105 says, “Your word is a lamp to my feet…” Though not using the word “Law,” the Psalmist equates God’s revealed word, His instructional standard,  with guiding obedience, echoing torah’s broader meaning of directional teaching.

Summary of Lexical and Theological Insights

Law (torah) = God’s authoritative instruction, teaching, and direction, often covenantal but not always legal. Law (nomos) = a binding standard or governing principle, sometimes referring to Moses’ law, sometimes moral law, sometimes a spiritual principle.

The Law reveals God’s will and character (Ps 19:7), defines and exposes sin (Rom 3:20), tutors God’s people toward Christ (Gal 3:24), is fulfilled and culminates in Christ (Matt 5:17; Rom 10:4) and is obeyed through the Spirit’s power in believers (Rom 8:4).

Application

The biblical concept of Law is not narrow legislation but a divine blueprint for life, worship, righteousness, and covenant identity. To “love the Law” is to love God’s instruction, and to reject the Law is to reject the God who speaks it.

Believers today should:

1.     View God’s commands as life-giving instruction, not mere restriction (Ps 1:2).

2.     Use Scripture’s Law rightly: to expose sin, not earn salvation (Rom 3:20).

3.     Trust Christ as the fulfilment and goal of the Law (Matt 5:17).

4.     Walk by the Spirit to live out God’s righteous standard (Rom 8:4).
