There’s something uncomfortable about these words of Jesus. They don’t sound soft… they sound direct. Almost confronting.
He said it clearly in Matthew 5:33–37: we don’t need to swear by anything; our “yes” should be yes and our “no” should be no… because anything beyond that comes from the evil one.
And that… hits.
Because He’s not just talking about religious oaths. He’s talking about something deeper: the integrity of the heart.
At the time when Jesus spoke these words, many people were used to making oaths so others would believe them. Saying “yes” or “no” wasn’t enough; they felt they had to swear by heaven, by earth, by Jerusalem, or by something sacred to make their words sound more serious. But Jesus was showing them that a person with integrity doesn’t need to decorate their words with oaths. Their life should be enough proof of what they say.
But Jesus breaks that pattern.
Not because swearing is the problem… but because it reveals the problem.
When you need to add something extra to your words so people will believe you… it’s because your words have already lost their weight.
And that’s where He says something strong: anything beyond a simple “yes” or “no”… comes from the evil one.
He’s not saying that every unfulfilled promise literally makes you “of the devil.” He’s pointing to something more subtle… deeper… more honest.
The origin.
Because the enemy has always worked the same way: distortion, deception, half-truths. As it says in John 8:44, he is the father of lies… and everything that moves away from truth somehow reflects that same pattern.
And when we promise something we don’t keep, when we say “yes” knowing we might not follow through, when we use words just to get through the moment… we step, without realizing it, into that same ground.
It’s not just a mistake.
It’s a disconnection between what you say… and who you are.
And that, little by little, weakens the soul.
Jesus didn’t come to complicate our lives… He came to simplify them. To make our lives so clean, so transparent, that we don’t need to add anything extra.
In fact, this same teaching is repeated in James 5:12: let your “yes” be yes and your “no” be no… so that you don’t fall.
So that when you say “yes”… people can rest.
And when you say “no”… they can too.
Because there are people who no longer trust what you say… not out of malice, but because of history.
Promises that weren’t kept.
Words spoken lightly.
Commitments forgotten.
And maybe, if we’re honest… we’ve all been there.
But here’s the beautiful part… the hopeful part.
This is not to condemn you.
It’s to realign you.
To bring you back to a life where your words regain their value… not because of what you say… but because of who you are.
Let me leave you with this thought: is your “yes” really yes… or does it depend on the moment, the emotion, or convenience?
Because in the end, it’s not about speaking better…
It’s about being true.
I invite you to join me in this prayer:
Father, help me to be a person of integrity, that my words may be true and reflect what is in my heart. In the name of Jesus Christ, Amen.
We are Christians, connecting hearts with Christ.
