Why is obeying God's laws crucial?
Why is obedience to God's purification laws crucial according to Numbers 31:21?

Setting the Scene

Numbers 31 recounts Israel’s victory over Midian. After the battle, Eleazar addresses the returning soldiers:

“Then Eleazar the priest said to the men of war who had gone to battle, ‘This is the statute of the law that the LORD commanded Moses.’” (Numbers 31:21)

The instruction that follows details how every item and person exposed to war’s defilement must be purified before re-entering the camp.


Why Obedience Matters: Core Reasons Drawn from the Verse

• Divine Origin

– Eleazar calls the purification rule a “statute of the law that the LORD commanded.”

– Because God Himself issues it, obedience is never optional (cf. Deuteronomy 6:17).

• Preservation of Holiness

– War contact rendered soldiers and spoils ceremonially unclean. Obedience ensured the camp remained holy, “for the LORD your God walks in the midst of your camp” (Deuteronomy 23:14).

Leviticus 11:44: “Be holy, for I am holy.”

• Protection from Judgment

Numbers 19:20 warns that ignoring purification brings cutting off from the community.

– Obedience spared Israel from corporate guilt and divine discipline (see also Joshua 7:1, 12).


Holiness Safeguards Fellowship

• Sin and impurity erect barriers (Isaiah 59:2).

• Purification restored relational closeness so God could dwell among His people without consuming wrath (Exodus 25:8; Hebrews 12:29).


Foreshadowing the Ultimate Cleansing

• Fire and water in Numbers 31 picture a deeper need met in Christ:

– Fire: refining judgment (Malachi 3:2–3).

– Water: washing of regeneration (Titus 3:5).

Hebrews 9:13-14 connects Old Testament cleansing rituals to the superior purifying blood of Christ.


Distinctiveness of the Covenant People

• By obeying, Israel showcased a lifestyle different from the surrounding nations (Deuteronomy 7:6).

• Their visible purity testified to the one true God (Psalm 67:1-2).


Consequences of Disobedience

• Personal loss: being “cut off” (Numbers 19:20).

• Communal loss: God’s presence withdrawn, victory forfeited (Joshua 7:12).

• Spiritual dullness: unconfessed impurity quenching fellowship and blessing (Psalm 32:3-4).


Applying the Principle Today

• Christ has fulfilled the ceremonial law, yet the call to purity endures (1 Peter 1:15-16).

• Practical obedience now involves:

– Regular self-examination and confession (1 John 1:9).

– Separation from contaminating practices (2 Corinthians 6:17).

– Pursuit of “holiness without which no one will see the Lord” (Hebrews 12:14).

Obeying God’s purification laws in Numbers 31:21 wasn’t a minor ritual detail; it was—and remains—a vital expression of reverence, holiness, and heartfelt allegiance to the Lord who dwells among His people.
