Lo Tissa: Blacking Out the Borrowed Oath

Sign a sample contract marked 'I swear to God', then black out that line. Jesus' teaching on oaths becomes a call to truthful character, not borrowed authority.

Big Idea

If your yes needs God's name attached to be believed, the problem is not the sentence but the character behind it.

Delivery Script

Hook Some lies wear religious clothes. Jesus strips them back to yes and no.

1. Hold up the contract. [hold the clipboard with the sample contract up to the room] Here is a promise that does not trust itself. You can feel it, can't you. Someone wrote this down and still felt the need to reach for something bigger than their own word.

2. Name the borrowed line. [point to the line reading 'I swear to God'] This line borrows God's name to make my words sound stronger. Not because the truth demands it. Because the speaker is not sure you will believe them without it.

3. Read the text. [lower the clipboard slightly, speak directly] Jesus saw this pattern. Listen. [read Matthew 5:33-37 aloud] Do not swear at all. Let your yes be yes and your no be no. Whatever is more than this comes from the evil one. Not a soft caution. A clean cut.

4. Black it out. [uncap the marker slowly, draw it across the oath line in one deliberate stroke] Watch. Gone. That line was never load-bearing. If the promise underneath it is honest, it does not need God's name bolted to the outside. If the promise is hollow, His name cannot save it.

5. Speak the commandment. Lo tissa. The third commandment does not only mean do not curse. It means do not carry or lift up the Name into emptiness, into falsehood, into worthlessness. [pause] God's name is not a prop for weak truthfulness. The moment you invoke Him to shore up a word you are not sure you will keep, you have not made the oath holier. You have made His name cheaper.

6. Sign it plainly. [pick up the pen, sign your name clearly at the bottom] Jesus says the disciple's yes should be heavy enough to stand without pawning God's authority. Your name. Your word. That is the standard. [set the clipboard down] If your yes needs God's name attached to be believed, the problem is not the sentence. It is the character behind it.

Land This is not a teaching about legal documents or religious courtrooms. It is a call to become the kind of person whose plain words can be trusted. The cure for careless oaths is not better formulas. It is a truthful life that does not need formulas.

Call to action This week, make one promise smaller and truer. Say only what you will actually do, then do it.

Props & Setup

Props Required

  • 1
    Sample contractWrite in large letters: I swear to God. Add SAMPLE across the top.
  • 2
    Black markerThick enough for the blacking-out action to be visible.

Setup Instructions

  1. 1Prepare a sample document with enough white space for the line to be seen.
  2. 2Place a scrap sheet underneath so marker does not stain the table.
  3. 3Mark Matthew 5:33-37 and Exodus 20:7 in your Bible.

Stage Execution

  1. 1Hold up the sample contract. Say: 'Here is a promise that does not trust itself.'
  2. 2Point to the line 'I swear to God'. 'This line borrows God's name to make my words sound stronger.'
  3. 3Read Matthew 5:33-37.
  4. 4Take the marker and black out the oath line slowly.
  5. 5Say: 'Lo tissa means do not carry or lift up the Name for emptiness, falsehood, or worthlessness. God's name is not a prop for weak truthfulness.'
  6. 6Sign the contract with only your name. 'Jesus says the disciple's yes should be heavy enough to stand without pawning God's authority.'

Safety Notes

Use a clearly fake contract, not a real legal document. Use a non-toxic marker and protect the table from ink bleed.

Theological Grounding

Matthew 5:33-37 addresses oath systems that attempted to grade truthfulness by what was sworn upon. Jesus drives His disciples back to plain speech: yes as yes and no as no. The third commandment deepens this because God's name must not be carried into empty or false speech; invoking Him to prop up unreliable words profanes the One whose name is truth.

Preacher Tips

  • Avoid turning this into a narrow lesson about swear words. The deeper issue is borrowing God's name to authenticate ourselves.
  • Use a fake contract. Real documents make people think about law rather than discipleship.
  • Name everyday phrases: 'I swear to God', 'God is my witness', 'on God's name'. Keep the tone searching, not smug.
  • If preaching to teens, connect it to exaggeration, screenshots, promises in chats, and needing dramatic language to be believed.

If Things Go Wrong

1People think all formal legal oaths are being addressed exhaustively.

Recovery: Say, 'The sermon is about the heart and ordinary truthfulness, not giving legal advice about court procedure.'

2The black marker bleeds through.

Recovery: Use the bleed as a line: 'False speech always leaves a mark.' Then protect the table next time.

3Hearers reduce the lesson to avoiding one phrase.

Recovery: Return to character: 'Jesus wants people whose plain words can be trusted.'

Adaptations

young children

Use two cards, yes and no. Say, 'Jesus wants us to tell the truth without adding big words.'

older children

Have children identify promise phrases that sound big but may hide dishonesty.

small group

Ask members where they are tempted to over-explain because their track record is weak.

academic

Compare Matthew 5, Exodus 20:7, James 5:12, and Second Temple oath formula debates.

Response Prompts

1.Where do your words need extra decoration because trust has become thin?

2.What would it take for your yes to be enough?

3.How have you used God's name casually to protect your own credibility?

Application Questions

  • 1How does the third commandment relate to everyday speech?
  • 2Why does Jesus connect extra oath language with evil?

Call to Action

This week, make one promise smaller and truer. Say only what you will actually do, then do it.

Focus Note

The more I need to add, the more you should wonder why my plain word is not enough.

Cultural Notes

Oath language varies widely. In some settings, God's name or sacred phrases are invoked casually to strengthen credibility. In cultures where honour formulas are normal, distinguish respectful seriousness from manipulative religious guarantee.
