How we treat others reveals the condition of our hearts

There is a simple truth that cuts through centuries of history and lands squarely in the middle of our everyday lives: how we treat other people matters. It matters more than we often realize, and it reveals something far deeper than mere manners or social courtesy. The way we treat others is a window into the condition of our own hearts.

This truth runs through the book of Jeremiah with remarkable clarity. As God addresses the kings of Judah, the charges brought against them are not abstract theological failures alone. They are concrete, observable, human failures. People were being robbed. Workers were going unpaid. The poor were being oppressed. Foreigners, orphans, and widows were being mistreated. And God's response was unambiguous: this is unacceptable, and it will not go unanswered.

The Heart Behind the Behavior
Before examining what God said to those specific kings, it is worth stepping back to understand the root issue. The people of Judah had drifted into idolatry. Their hearts had wandered away from God and toward the gods of the surrounding nations. This is the pattern that Jeremiah describes throughout his writings, and it is the same pattern that surfaces in human relationships today.

When a person's heart is not aligned with God, it shows up in how they treat others. The two things are inseparable. Jeremiah 17 reminds us that the heart is desperately wicked and deceitful above all things. The kings of Judah were a living demonstration of that reality. Their treatment of the people around them was not an isolated problem. It was the outward expression of hearts that had turned away from God.

The King Who Built on the Backs of Others
One of the most striking examples in Jeremiah 22 is the indictment of King Jehoiakim. He was consumed with building a magnificent palace, paneled with fine cedar, painted in lovely colors, filled with large rooms and grand windows. On the surface, it sounds impressive. But God pulls back the curtain and reveals what was actually happening. The palace was being built through forced labor. Workers were not being paid. Jehoiakim was constructing his legacy on the suffering of the people beneath him.

God's response is pointed and direct. A beautiful palace does not make a great king. Jehoiakim's father, Josiah, had also enjoyed prosperity. But Josiah used that prosperity differently. He gave justice and help to the poor and needy. He dealt honestly. He cared for the vulnerable. And God says something remarkable about Josiah: that is what it means to know me.

That phrase deserves to sit with us for a moment. To know God is not merely a theological position or a spiritual experience confined to private devotion. To know God is to reflect His character in the way we engage with the people around us. Josiah understood this. Jehoiakim did not.

Grace in the Merge Lane
This principle does not stay confined to ancient kings and royal courts. It shows up in the most ordinary moments of daily life. Consider a woman who commutes eighty miles a day through heavy traffic. One afternoon, a driver beside her signals to merge in front of her. Annoyed, she speeds up to block the move. The other driver eventually finds a way over and exits the highway. Conviction settles in immediately. That was not a gracious response.

Then, just moments later, she approaches a closed toll lane and needs to merge herself. A truck driver sees her signal and waves her in. Grace, extended freely, even though she had just withheld it from someone else.

This small story carries a large truth. We are often far quicker to demand grace for ourselves than we are to extend it to others. And when we withhold grace, we are not simply being rude in traffic. We are failing to represent the heart of the God we claim to follow.

The Words We Speak
The treatment of others does not only show up in our actions. It lives in our words as well, and sometimes the words we speak about people when they are not present do more damage than anything we might do directly.

It is easy to talk about someone when we feel wronged. It is easy to share our version of a story without knowing the full picture. Someone walks past us at church without saying hello, and we construct an entire narrative about their character. Someone leaves a ministry under difficult circumstances, and we repeat their complaints to others without knowing what actually happened. A public figure claims faith while speaking about others with contempt, and the watching world draws its conclusions about Christianity from what it sees.

None of this is harmless. Every careless word, every negative characterization, every story told from only one side has consequences. It shapes how others see people. It can close doors that God is trying to open. It can drive away someone who was just beginning to consider whether faith might be real.

Representing God Well
The call embedded in Jeremiah 22 is the same call that echoes throughout the New Testament. We are to be people who reflect the character of God in our dealings with others. Not because every person we encounter deserves our kindness. Not because people always treat us well in return. But because we represent someone whose grace is given freely, not earned.

Josiah gave justice and help to the poor and needy, and God said that is what it means to know me. That standard has not changed. The question worth sitting with today is whether the people around us, believers and unbelievers alike, would recognize the character of God in how we treat them.

The condition of our hearts will always find its way to the surface. It shows up in traffic. It shows up in the words we choose. It shows up in whether we pay the people who work for us, whether we stand up for those who cannot stand up for themselves, and whether we extend to others the same grace we so readily receive.

How we treat others is not a peripheral concern. It is a direct reflection of who we are on the inside, and ultimately, of who we believe God to be.
