Meaning of "My words a fire in mouth"?
What does "I will make My words in your mouth a fire" mean?

Text

“Therefore this is what the LORD God of Hosts says: ‘Because you have spoken this word, I will make My words in your mouth a fire, and this people the wood it consumes.’” (Jeremiah 5:14)


Setting and Audience

• Jeremiah is ministering in Judah about 600 BC.

• The nation is hardened in idolatry, immorality, and injustice (Jeremiah 5:1–13).

• God announces imminent judgment through Babylon, yet still pleads for repentance.

• Jeremiah has just repeated God’s warning; now the LORD responds with the vivid promise of verse 14.


Why the Image of Fire?

Fire in Scripture consistently communicates:

• Judgment that burns away resistance (Isaiah 66:15–16).

• Purification that refines what is valuable (Malachi 3:2–3).

• Irresistible, contagious power (Jeremiah 20:9).

Here, the Lord blends all three. His word through Jeremiah will:

1. Ignite conviction.

2. Consume rebellion.

3. Spread until every unrepentant heart is exposed.


What It Meant for Jeremiah

• Divine authority – God Himself places the message; Jeremiah need not manufacture eloquence (cf. Jeremiah 1:9).

• Protective validation – opposition will not extinguish the message (Jeremiah 1:18–19).

• Visible results – the people will feel the searing reality of the word; it will not return void (Isaiah 55:11).


Scripture Echoes

• “Is not My word like fire…?” (Jeremiah 23:29) – same metaphor used later to rebuke false prophets.

• “Elijah answered, ‘If I am a man of God, may fire come down…’ ” (2 Kings 1:10) – prophetic fire verifies divine origin.

• “Fire proceeds from their mouths and devours their enemies.” (Revelation 11:5) – end-times witnesses wield similar, fiery speech.

Hebrews 4:12 – though using sword imagery, stresses the penetrating effectiveness of God’s word.

Luke 24:32 – the risen Christ causes hearts to “burn” when He opens Scripture, highlighting its refining warmth for believers.


Powerful Consequences for Judah

• If they resist, the word becomes consuming judgment: “this people the wood it consumes.”

• If they repent, the same fire purifies; God always leaves a remnant (Jeremiah 5:18).

The outcome hinges not on the prophet but on the hearers’ response.


Personal Application Today

• God’s word retains its fiery nature.

– It exposes sin, demands decision, and purifies character.

• When we speak Scripture faithfully:

– We rely on divine power, not human persuasion (1 Thessalonians 1:5).

– We should expect mixed reactions—softened hearts or hardened rejection (2 Colossians 2:15–16).

• Let the fire do its work:

– Welcome its refining heat in personal sanctification (1 Peter 1:7).

– Share it with bold compassion, trusting God for the results (2 Timothy 4:2).


Closing Thoughts

“I will make My words in your mouth a fire” assures every faithful messenger that Scripture remains a living flame—able to warm the repentant and consume stubborn unbelief. The task is simply to open the mouth; God supplies the fire.
