Link 1 John 5:21 to Exodus 20's 1st Law.
How does 1 John 5:21 connect with the First Commandment in Exodus 20?

Setting the stage

- 1 John 5:21: “Little children, keep yourselves from idols.”

- Exodus 20:3: “You shall have no other gods before Me.”

- Both verses issue the same straightforward command: give God unrivaled devotion. John’s final sentence restates Sinai’s first word to Israel, showing that nothing has changed about God’s demand for exclusive worship.


First Commandment: Exclusive Allegiance

- God introduces Himself as Redeemer before issuing the command (Exodus 20:2), grounding obedience in His saving work.

- The phrase “before Me” means “in My presence,” reminding us that God sees every rival affection.

- By forbidding idols, God guards the covenant relationship—He will not share His glory (Isaiah 42:8).


1 John 5:21: The Echo of Sinai

- John addresses believers as “little children,” highlighting family intimacy yet also calling for childlike trust.

- “Keep” (Greek: phylaxate) = guard, watch over, protect. The threat isn’t theoretical; idols press constantly.

- John’s entire letter contrasts the true God and His Son with false spirits (1 John 4:1–6); the closing line distills that contrast into a single command.

- By placing it at the end, John shows the first commandment is still the last word for New-Covenant believers.


What Counts as an Idol Today?

Physical figures remain around the world, but Scripture widens the term:

Colossians 3:5 — “greed, which is idolatry.”

Ezekiel 14:3 — “These men have set up idols in their hearts.”

Philippians 3:19 — “their god is their stomach.”

Anything—possession, pleasure, person, ideology—that dethrones God becomes an idol.


How to Keep Ourselves from Idols

1. Treasure God’s revelation

Psalm 119:11 — hiding the Word in our hearts fortifies against counterfeit gods.

2. Love the Lord wholly

Deuteronomy 6:5; Matthew 22:37 — wholehearted love leaves no room for rivals.

3. Flee temptation

1 Corinthians 10:14 — “Therefore, my beloved, flee from idolatry.”

4. Walk in the Spirit

Galatians 5:16 — living by the Spirit starves fleshly desires that birth idols.

5. Examine loyalties

2 Corinthians 13:5 — regular self-examination uncovers hidden altars.

6. Worship in community

Hebrews 10:24–25 — fellowship guards against drift by mutual encouragement.


Why This Matters for Fellowship with God

- Idolatry severs intimacy; true joy flows only from the real God (Psalm 16:11).

- Eternal life is knowing the Father and the Son (John 17:3); idols offer emptiness.

- The first commandment and 1 John 5:21 together call believers to relentless loyalty, ensuring that the One who saved us remains first in our hearts, homes, and hopes.
