Guarding Your Heart: Speaking Truth to One Another Well

From the sermon preached on July 5, 2026

Speaking truth to one another is not a soft suggestion buried in an old prophet's sermon. It is God's clear instruction for anyone trying to live at peace after a season that left them tired and guarded. In Zechariah 8, God tells a rebuilding, weary people exactly how to treat each other: tell the truth, and stop devising evil against others who have already been hurt enough.

That instruction lands differently depending on where you are standing. Maybe you are the one still replaying what someone did to you, turning it over at night like a stone in your pocket. Maybe you are the one who said something you cannot take back, and the silence since then has said even more.

The prophet Zechariah spoke to Jewish exiles who had just been given permission to return home and start over. They were tired, underfunded, and half convinced the whole project was doomed. Into that exhaustion, God did not offer a pep talk; he offered a promise, and a set of instructions for how to live once the promise started coming true.

God's jealousy for his people sounds, on the surface, like something to be uneasy about. Nobody wants a jealous friend, let alone a jealous God. But God's jealousy for his people in Zechariah 8 is not insecurity; it is the fierce protectiveness of someone who has already given everything and will not stand by while what he loves is handed to something smaller.

The Hebrew word behind it pictures a face flushing red with deep feeling, the kind of reaction a parent has watching a child walk toward something that will hurt them. That is closer to what God's jealousy for his people actually means. He is not possessive over what is not his; he is protective over what already belongs to him.

Think about the pull toward things that promise to fill you and never quite do: a job that consumes you, a relationship you keep returning to even though it costs you, a habit you cannot fully name out loud. Watching someone you love choose something that cannot be what they need is its own particular grief, and God's jealousy for his people comes from that same place.

Here is one honest step: name the thing you have been leaning on instead of God, even just to yourself, without excusing it.

Speaking truth to one another was God's first instruction to a people trying to rebuild what had been broken. Not clever truth, not comfortable truth, but truth that lines up with what God says is real, spoken plainly to people who need to hear it. Guarding your heart from sin starts here, because the two are connected in ways we do not always notice.

There is a real temptation to treat truth as something flexible, something that bends to fit whatever feels right in the moment. But truth that changes depending on who is talking is not truth at all; it is preference wearing a nicer word. Guarding your heart from sin means refusing that trade, even when it costs you the easier version of the story.

Sometimes the clearest truth is small and almost funny. One pastor used to call the black cattle he passed on the drive to Gilman "black llamas," just to make his kids laugh. His son thought it was hilarious. His daughter was having none of it; those were cows, and speaking truth to one another started right there, in the back seat, long before it mattered anywhere bigger.

Guarding your heart from sin rarely happens in one dramatic moment; it happens in small, ordinary honesty like this. Try this today: pick one place where you have been softening the truth to keep the peace, and say the honest version out loud, gently but clearly.

Rebuilding after spiritual exile is not just an ancient Israelite problem. It is what it looks like to come out of any hard season, whether that season was your own doing or something done to you, and try to live differently on the other side of it. Zechariah promised a rebuilt Jerusalem: old people sitting safely in the streets, children playing without fear, a city no longer defined by what tore it down.

That promise came with a warning attached. God's instruction was not only to speak truth, but to stop devising evil against others, to quit plotting how to ruin a reputation or quietly get even. Rebuilding after spiritual exile cannot happen in a heart still running the old scripts of revenge, even the quiet, private, never-said-out-loud kind.

This is where the sermon got personal: a father watching his fourteen-year-old daughter grow up and feeling the crushing weight of knowing she could be hurt by someone incapable of being what she needs. That fear, multiplied, is close to what God feels watching his people run toward things that cannot fill them, yet he is not devising evil against others in return; he stays patient, even while honest about the cost of sin.

Devising evil against others keeps a person locked in the very exile they are trying to leave. Rebuilding after spiritual exile means letting go of the plan to get even and trusting the one who promised a new season is not finished writing it. One honest step: the next time you catch yourself rehearsing what you would say to get back at someone, stop mid-sentence and ask God to change the sentence instead.

Zechariah 8 is built around a contrast the whole sermon leans on: seventy years of wrath, and then a season of mercy that starts the moment God says it does. The people had not earned the shift. They were simply told it had come, and then given clear instructions for how to live inside it. Zechariah 8:16-17 names those instructions directly: speak truth, render honest judgment, make peace, stop devising evil, and refuse false oaths.

Zechariah 8 does not ask the people to earn the new season. It asks them to live like it is already true, because it is.

There is a particular kind of tired that comes from carrying a grudge or a half-truth for years without ever setting it down. It is the weight of knowing exactly what you would say if you finally let yourself say it, and choosing, so far, not to. That weight does not care whether you live in town or out past the last stoplight.

Whether you are in Watseka, tucked into Ashkum or Goodland, or somewhere among the fields between Danforth and Milford, that same invitation to rebuild something honest is open to you across Iroquois County and into Newton County.

Zechariah told a worn-out people their season of wrath was over and a season of mercy had begun, and their part was simple: keep speaking truth to one another, and stop devising evil against the people God still loves. That instruction is not locked in the past; it is available the next time you are tempted to hold a grudge or nurse a plan to get even.

There is a place for you at Trinity Church across all three campuses: Ashkum, Goodland, and Watseka. You are welcome to come as you are, plan your visit below.
