How should believers respond to blasphemy?
What actions should believers take against those who misuse God's name?

Setting the Context

“ For they speak of You with evil intent; Your adversaries misuse Your name.” – Psalm 139:20

Psalm 139 is David’s intimate meditation on God’s omniscience and holiness. In verse 20 he laments those who “misuse” (or “take in vain”) God’s name, exposing hearts that oppose the Lord.


Recognizing the Weight of God’s Name

Exodus 20:7 – “You shall not take the name of the LORD your God in vain…”

Leviticus 19:12 – Swearing falsely by His name profanes it.

Philippians 2:9-11 – The name of Jesus is exalted above every name.

God’s name represents His character, authority, and glory. Treating it lightly assaults His honor.


Practical Actions for Today

1. Separate from the Sin, Not Necessarily the Sinner

Psalm 139:21-22 underscores David’s moral distance from God-haters.

2 Corinthians 6:17 – “Come out from among them and be separate.”

• Avoid joining in conversations or media that trivialize God’s name.

2. Speak Up Respectfully

Ephesians 4:15 – “Speak the truth in love.”

• Gently but firmly note the misuse: “I believe God’s name is holy; let’s honor Him.”

Proverbs 15:1 – A soft answer turns away wrath.

3. Model Reverent Speech

Ephesians 4:29 – Let only edifying words proceed.

Colossians 4:6 – Season speech with grace.

4. Offer Gospel Hope

1 Peter 3:15 – Be ready to give a reason for the hope within, with gentleness and respect.

• Remind offenders that forgiveness is available through Christ who bore every blasphemy on the cross (Luke 23:34).

5. Pray for Their Repentance

Matthew 5:44 – “Pray for those who persecute you.”

• Ask God to open their eyes to His majesty and mercy.


Guarding Our Own Speech

James 3:9-10 warns that blessing God and cursing people from the same mouth is hypocrisy.

Psalm 19:14 – “Let the words of my mouth… be acceptable in Your sight.”

Regular self-examination ensures we do not unconsciously slip into irreverence.


Connecting With the Wider Witness of Scripture

Malachi 1:11 – God’s name will be great among the nations; our reverence advances that purpose.

Acts 4:12 – Salvation is found in no other name; guarding it safeguards the gospel witness.


Responding When Confronted With Blasphemy

• Maintain composure; anger never accomplishes God’s righteousness (James 1:20).

• Refuse to laugh or remain silent—silence can imply consent.

• Point to Scripture, not personal opinion, as the source of authority.


Living as Light in a Dark World

By honoring God’s name in speech, conduct, and courage, believers contrast the culture’s flippancy with sincere reverence. Such fidelity turns Psalm 139:20 from a lament into a rallying cry for holiness, declaring through word and deed that the Lord’s name is indeed “holy and awesome” (Psalm 111:9).
