Let Your Yes Be Yes: Trustworthy Discipleship

Aug 09, 2026

Devotional

Day 1: When Emus Expose Our Empty "I Swear!"

A teenage girl’s frantic claim about an emu chase seemed absurd—until the news proved it true. Her history of exaggeration made even truth hard to believe. This mirrors how casual vows like “I swear to God” erode trust when our words routinely outpace our integrity. When lives don’t align with promises, even honest claims ring hollow. Let simple truth replace theatrical oaths. [52:50]

“Let what you say be simply ‘Yes’ or ‘No’; anything more than this comes from evil.” (Matthew 5:37, ESV)

Reflection: What casual phrase do you overuse to make others believe you (“I swear,” “I promise,” etc.)? How might replacing it with quiet consistency rebuild trust?

Day 2: Ghosting the Body’s Supper

A church member’s habit of RSVP-ing “yes” to multiple Thanksgiving dinners—then skipping all—left hosts scrambling. Unkept commitments force others to compensate, straining the body like a rolled ankle harming the knee. Reliability isn’t about perfection but prioritizing the impact of our “yes” on Christ’s community. [41:11]

“If you vow a vow to the Lord your God, you shall not delay fulfilling it, for the Lord your God will surely require it of you.” (Deuteronomy 23:21, ESV)

Reflection: When have you last canceled a commitment for convenience? How might following through next time tangibly serve Christ’s body?

Day 3: Bumper Sticker Faith Without the Brakes

A hypothetical question lingers: If you removed Christian symbols from your car or clothes, would your neighbors still recognize your faith? Integrity isn’t advertised but demonstrated through unswerving honesty in taxes, gossip, and keeping appointments. The world notices when our “yes” outlives mood swings. [56:16]

“Therefore, having put away falsehood, let each one of you speak the truth with his neighbor, for we are members one of another.” (Ephesians 4:25, ESV)

Reflection: Where does your private integrity (emails, texts, chores) lag behind your public faith symbols? What mundane act of truthfulness could bridge that gap today?

Day 4: When Ankles Ail the Whole Body

Favoring a sore ankle altered the pastor’s gait until his knee rebelled. Similarly, one member’s unreliability—like forgetting Bibles on mission trips or ghosting service teams—forces others to overcompensate. The church thrives when each part carries its weight without hidden excuses. [37:20]

“If a man vows a vow to the Lord…he shall not break his word. He shall do according to all that proceeds out of his mouth.” (Numbers 30:2, ESV)

Reflection: What unresolved habit (chronic lateness, half-hearted volunteering) might be straining others? How could addressing it free the body to flourish?

Day 5: The Zorb Bulb of Self-Protection

Some withdraw from church commitments to avoid being hurt again, wrapping themselves in protective bubbles. Yet growth happens through friction—showing up even when others disappoint. Jesus didn’t shield himself from betrayal but let love risk repeated wounds. [52:05]

“Do not lie to one another, seeing that you have put off the old self with its practices and have put on the new self.” (Colossians 3:9-10, ESV)

Reflection: Where has self-protection made you a passive observer in the body? What small “yes” could puncture the bubble this week?

Sermon Summary

James 5:12 puts the issue right out front: “above all, my brothers, do not swear, not by heaven, by earth, or anything else, but let your yes be yes and your no be no, or you will be condemned.” Jesus had already said the same thing in Matthew, and that repetition shows the weight of it. The problem is not just bad manners or forgetfulness. The problem is a heart that speaks one thing and lives another.

The church is called to be one body, moving in the same direction, with each person serving the function God has given. Words can either help that body move together or they can make the whole body limp. One rolled ankle can make the knee start hurting, and one unreliable part of the body can put stress on other parts. When someone says yes and does not show up, or says no by ghosting and avoiding accountability, the whole body feels it.

The culture is full of pictures that are not true, social media posts that are not true, polished images that are not true, and people who are all after themselves. The sad thing is that the church often does not look different. If God’s people need extra oaths, like “I swear to God,” to make words believable, then something is already wrong. A faithful disciple should not need a pile of promises on top of a simple yes or no.

The Old Testament allowed oaths, but God’s law still demanded truth. Numbers says a person must not break his word, and Leviticus warns against swearing falsely by God’s name. James presses that same concern deeper. The real question is, why not let life confirm the reliability of words? Why not let actions show that speech is true?

Faithfulness is not an occasional thing. Faithful discipleship is an all the time, every time thing. Bible studies, service commitments, covenant partnership, financial support, showing up, answering honestly, and doing the hard thing all become places where yes is tested. Noncommitment often hides behind waiting for something better, but the body still suffers when promises are treated lightly.

God’s Word is both written and incarnate. Jesus is the living Word, and Scripture forms the life of the believer into his image. If speech sounds biblical but actions do not match it, then the witness becomes hollow. A bumper sticker, a Jesus shirt, or a church name cannot replace a life where yes is yes and no is no. The testimony of truthfulness must be the life that is lived.

Key Takeaways

1. Words reveal the heart. James does not treat truthfulness as a small social habit. The issue goes beneath swearing and excuses into the place where desire, fear, and self-protection live. A mouth that needs extra oaths may be exposing a life that has not become dependable before God. [45:05]
2. Faithfulness strengthens the body. The body of Christ feels the weight when one part does not do what it said it would do. A missed commitment is rarely isolated, because another part of the body must carry the strain. Dependability becomes a quiet form of love, because it refuses to make another person limp. [36:56]
3. Noncommitment avoids discipleship. Refusing to sign up for anything can look harmless, but it can also be a way to avoid accountability. The desire to remain free for a better option slowly trains the soul to treat the church as optional. Faithful discipleship requires a word strong enough to be trusted. [49:09]
4. The life is the oath. Jesus’ people do not need to swear by heaven, earth, or anyone’s grave when their lives have already become credible. The steady pattern of showing up, speaking plainly, and following through becomes the testimony. Integrity is not loud, but it becomes very visible in a world that does not know who to trust. [52:05]
5. The Word becomes visible. God’s Word is written in Scripture and incarnate in Jesus Christ. A disciple formed by that Word cannot leave truth on the page while living a contradiction in public. The world sees the gospel more clearly when declared words and daily actions begin to match. [55:05]

Bible Reading

James 5:12
“But above all, my brothers, do not swear, either by heaven or by earth or by any other oath, but let your ‘yes’ be yes and your ‘no’ be no, so that you may not fall under condemnation.” [34:04]

Matthew 5:37
“Let what you say be simply ‘Yes’ or ‘No’; anything more than this comes from evil.” [33:25]

Numbers 30:2
“If a man vows a vow to the LORD, or swears an oath to bind himself by a pledge, he shall not break his word. He shall do according to all that proceeds out of his mouth.” [35:22]

Leviticus 19:12
“You shall not swear by my name falsely, and so profane the name of your God: I am the LORD.” [35:46]

Observation questions

In James 5:12, what specific kinds of swearing are forbidden, and what simple alternative is given in their place?
What repeated phrase appears in both James 5:12 and Matthew 5:37, and what does that repetition highlight about the importance of truthful speech? [33:30]
What everyday examples show how unreliable words can put stress on the rest of the body, especially when someone says yes but does not follow through? [36:28]
What examples are given of avoiding a clear no, such as ghosting or refusing to answer, and how does that avoid accountability? [38:32]

Interpretation questions

James says, “above all,” before giving this command. Why might truthfulness be treated as such a weighty issue in the life of the church?
If the Old Testament allowed vows but still required people not to break their word, what does that suggest about the deeper concern behind these passages? [34:21]
When a person feels the need to say, “I swear to God,” what might that reveal about trust, credibility, and the condition of the heart? [45:05]
If the body of Christ is meant to move together, why do broken commitments affect more than just the person who made them? [36:56]

Application questions

Where has speech become too casual lately—saying “I’ll pray about it,” “I’m praying for you,” or “I’ll be there” without really meaning to follow through? What would it look like to become more plain and truthful in those moments? [28:38]
Is there a place right now where a clear answer needs to be given instead of silence or delay? Would it be more faithful to offer an honest no than to avoid responding at all? [38:38]
What kinds of commitments are hardest to keep—showing up, serving, giving, responding, praying, or participating consistently? What usually gets in the way? [47:47]
Has noncommitment ever felt safer because it avoids accountability or leaves room for a better option later? How might that habit slowly weaken love for the church and responsibility to the body? [49:09]
When others have been unreliable, has that disappointment led to pulling back from serving or participating? How can someone resist repeating the same hurtful pattern that wounded them? [50:57]
If daily life is the real oath, what would make a neighbor, coworker, or family member recognize a Christian without a shirt, sticker, or label? [56:16]
What is one specific yes that needs to be honored this week, or one no that needs to be spoken clearly and kindly, so that words and actions begin to match more closely? [52:05]

#TrustAndRevival

“It's interesting because even today in our culture and our world, everything go through a judicial process to make sure that our yes is yes and our no is no because we really just can't trust anyone. We can't trust anybody. Because why? Because everyone's after themselves. Everyone's doing something shady. Everybody's doing this thing. And so the question of our our culture really is, who can we trust? And I love to say it's different inside the church, but it's not. It absolutely is not different inside the body of believers. But I firmly believe that if our church body was different than the rest of the world, there would be a revival that begins. If we actually said what we said and followed through on it, if our yes was yes and our no was no, do you know how that would change the body of believers? Do you know what that would look like?”

#LiveYourWord

“``At the heart of this context or this text is a simple question. Why not why not let our lives confirm the reliability of our words? Why not allow our words to confirm it? Why not our actions be revealing the truthfulness of what we say? As followers of Jesus, shouldn't we have such an integrity and a character and a truthfulness of a heart that is absolutely believable and dependable? Shouldn't our yes and our no just be sufficient in our world? There's no need to swear by something else because we've said yes. And you know what happens with yes and no? When it's truly yes is yes and no is no, we become trustworthy. And people begin to acknowledge that what we say is going to happen because we deliver when we say that we will.”

#ActionsRevealFaith

“And so our actions must back up what we say and what we declare. I gave a little hint of a nugget, then I'll finish with it. If it weren't for the bumper sticker on your car, if it weren't for the shirt that you wear, if you didn't tell people you went to Grace Ridge Church, would your neighbor know you're a Christian? Would your coworker? They would if our yes was yes and our no was no. If you recognize the witness and the testimony of declaring the word of God in a world that is so desperate to hear it.”

#FaithfulnessInAction

“You see, faithful discipleship as a body of believers does not need to have oaths behind it. It just needs to have faithfulness behind it. Faithful disciples just need to be faithful. What we say we're supposed to do, we should do. What the word of god says to do, we need to do it. When we say we're going to deliver or do something and we don't, what does that tell the world? What does it say to the nonbeliever? What does it say to the doesn't just hurt the body, but what does it say to those who are watching and witnessing and watching for g GRC and watching how we handle things, and yet we are still living in a manner that is not in line with what we're speaking.”

55s

#LetYourYesBeYes

“What happens if our yes is yes and our no is no? It means there's no reason to add on this caveat of an oath. I swear to god. I swear by my when we have to do that, it's because people don't trust us because what we say isn't truly what our lives indicate. And so what's his point here? Just let your yes be yes and your no be no. I challenged the congregation to think about this at the first service, but I'll give it to you now. I'll give you the nugget now, then I'll I'll finish at the end with the same thing. If you didn't have a bumper sticker on your car that identify that you're a Christian and didn't wear Jesus paraphernalia. Would anybody know?”

#KeepYourWord

“But what happens? Here's the truth of our society. We don't commit because we're waiting for something better to happen. We're looking for a better option, a better plan, something that we like. And so we are noncommittal. We also refuse to be emboldened by the word and say, you know what? I'm going to go do this. So we have this business's mission with a with a wedding venue. And we signed a contract with this couple. And I refuse to go back on it even if something changes and we're gonna lose money or a little bit of money. We'll we'll still make a profit, but I'm I refuse to go back on it. Why? Because that's our word.”

39s

#AlwaysReliable

“True disciples of Jesus Christ do not need to provide oaths to confirm their trustworthiness. The lives and their faithfulness confirm the reliability of their words. And so being reliable once in a while isn't sufficient. It is an all the time, every time thing. It's something that we do. It's something of who we are. It's our way of living as faithful followers of Jesus Christ.”

37s

#CarryYourPart

“But don't forget, two weeks ago, we talked about every single person has a function in the body, and every single person is what God uses for the fullness of his body. How about when we stand up and say, I'm gonna be a covenant partner. I'm gonna be participating in life of the church, yet we don't. How about we say financially, I'm gonna support the church, and and we really don't. How about when we say we're gonna do something and we just don't follow through? What happens? Other parts of the body have to step up to take and fulfill those roles.”
