Let Your Yes Be Yes Matthew 5:33–37

Let Your Yes Be Yes

Matthew 5:33–37

When Jesus speaks about oaths, He is not merely correcting a way of speaking.

He is exposing something deeper: the truthfulness of the heart.

People often strengthen their words with statements such as, “I swear,” “I promise,” or “I am telling the truth.”

But Jesus raises a deeper question:

Why should an ordinary word need an oath before it can be trusted?

In Jesus’ day, people could make distinctions between different kinds of oaths.

An oath made directly in God’s name might be treated as especially binding, while an oath by heaven, earth, Jerusalem, or one’s own head could be viewed as less serious.

Jesus rejects this kind of reasoning.

Heaven is God’s throne.

Earth is His footstool.

Jerusalem is the city of the great King.

Even our own lives are not fully under our control.

There is no part of life that exists outside God’s presence.

Every word we speak is spoken before Him.

That is why Jesus says:

“Let what you say be simply ‘Yes’ or ‘No.’”

Citizens of God’s Kingdom should not need complicated guarantees to make their words believable.

Their ordinary speech should be trustworthy.

Their “yes” should mean yes.

Their “no” should mean no.

There should not be one meaning spoken aloud and another hidden in the heart.

This is part of the deeper righteousness Jesus describes in the Sermon on the Mount.

Legalistic religion asks:

“How serious does an oath have to be before I am obligated to keep it?”

Jesus asks:

“Is your word true?”

This reaches into every part of life.

It concerns what we say at home, in church, at work, in ministry, in business, and in our everyday promises.

Every word belongs under the lordship of God.

Yet when we examine ourselves, we realize that our words have not always been completely truthful.

We exaggerate to make ourselves look better.

We hide details to avoid responsibility.

We change our words depending on who is listening.

And once again, the teaching of Jesus leads us to Jesus Himself.

Jesus did not merely speak truth.

He is the Truth.

His words and His life were perfectly united.

He promised obedience to the Father and obeyed all the way to the cross.

He spoke of His death and resurrection, and His words were fulfilled.

In Christ, we see the faithfulness of all God’s promises.

Christian truthfulness, therefore, is more than good character.

It is part of becoming like Christ.

As the gospel frees us from the need to protect our image and earn the approval of others, we become increasingly free to speak simply and honestly.

We do not need exaggeration to prove our worth.

We do not need deception to protect our identity.

Our security is already found in Christ.

So let our yes truly be yes.

Let our no truly be no.

And may our ordinary words become trustworthy because our lives increasingly reflect Jesus Christ, the faithful and true One.
