Article 1 of 4 | The King and Truthful Living | Matthew 5:31–37
by Dr Timothy Mann
Some passages of Scripture are easy to approach. Others make you want to slow down before you get there.
Matthew 5:31–37 is the second kind.
Jesus speaks here about divorce, remarriage, and oaths. For many people, these are not abstract topics. They are personal. They touch real stories, real regrets, and real questions some have carried quietly for years. Others may feel defensive before the passage even starts.
So let's say this plainly before we go any further.
Jesus is not trying to embarrass anyone. He is not delivering a cold legal lecture. He is not pretending that broken lives are simple. He is doing something far more careful than that.
The Pattern Jesus Keeps Using
If you've been walking through the Sermon on the Mount, you've noticed a pattern. Jesus keeps saying the same thing in different ways. "You have heard that it was said... But I say to you."
Every time He uses that structure, He's doing the same thing: He's exposing the gap between what people thought righteousness required and what it actually demands. The religious leaders of His day had become skilled at technical compliance. They knew how to navigate the law in ways that satisfied the letter while protecting the heart. They had learned, over generations, how to appear righteous while quietly avoiding the cost of actually being righteous.
Jesus comes for that gap. Every time.
In verses 21–30, He addressed murder and adultery, pressing past the external act to the anger and lust that produced it. Now in verses 31–37, He addresses divorce and oaths, two areas where people had built elaborate legal and verbal systems to manage the appearance of integrity without the reality of it.
The subjects change. The diagnosis stays the same.
The Inner-Person Problem
Jesus is not making the law harder. He's revealing what the law was always about.
Think about the person who stays technically within the rules while managing everything around the rules. The person who looks for loopholes. The person who phrases things carefully to preserve an exit ramp. The person who wants the benefits of commitment without the full weight of it. That person can look very righteous from the outside. Their paperwork is in order. Their words are correct. They've stayed within the lines someone drew for them.
Jesus says that's not enough. Kingdom righteousness is a different category entirely.
"For I say to you, that unless your righteousness exceeds the righteousness of the scribes and Pharisees, you will by no means enter the kingdom of heaven." — Matthew 5:20, NKJV
That statement from earlier in the chapter frames everything Jesus says in this section. The scribes and Pharisees were not careless people. They were meticulous. They studied the law, taught the law, lived visibly by the law. And Jesus says that kind of righteousness isn't enough to enter the kingdom.
Not because the law was wrong, but because they had found ways to satisfy it externally while protecting the heart from its actual demands.
What This Series Will Examine
Over the next three articles, we'll walk through Matthew 5:31–37 together. We'll look at what Jesus says about covenant faithfulness and what it means when legal procedures replace genuine integrity in lifelong commitments. We'll examine the elaborate system of oaths people had built to sound honest while leaving room for deception. And we'll land on Jesus' summary statement in verse 37, where He gives us the clearest possible picture of what truthful kingdom living looks like.
Along the way, we'll try to be honest about the places where this passage challenges us. Because it will.
But here's what I want you to hold onto from the beginning. Jesus does not expose sin to crush people. He exposes it to restore them. He confronts the inner-person problem because He intends to heal it. And the gospel He preached and purchased at the cross is precisely the power that makes genuine truthfulness possible in people who were not naturally inclined toward it.
Kingdom righteousness tells the truth. In commitments. In words. Before God.
The question this passage keeps asking is not, "Have I followed the rules?"
It's a more searching question than that:
Is my life actually marked by truthful living before God?
That question is worth sitting with before we go any further.
Application & Reflection
Before reading further in this series, take a few minutes with the question Jesus is really asking: not whether your outward behavior is acceptable, but whether your heart is marked by truthfulness before God. Is there a place in your life where you've learned to look compliant while quietly protecting your heart from what faithfulness actually demands? Don't rush past your first honest answer.
Reflection Questions:
- When you think about your own spiritual life, is there a gap between how you appear to others and what you know to be true before God? What does that gap reveal about where the heart is?
- Why do you think external rule-keeping is so much more comfortable than the kind of heart-level truthfulness Jesus is describing? What makes the inner-person standard more demanding?
Next: Article 2, "When Covenant Becomes Convenient," examines what Jesus says about divorce, covenant faithfulness, and what it means when legal procedure replaces genuine integrity in our deepest commitments.
