Keep Knocking - Justice

- 9/28/2025

I have never been what you would call handy. Just ask my

family what happens when I try to fix a sink. It turns out, you

can make it worse.

When I was in college, our Presbyterian student group

participated in a spring break build with the local Habitat for

Humanity chapter. I signed up, but I also clearly described

my qualifications and my experience. None and none. I

arrived the first day and was assigned by our project leader

to the front door. Now, I assumed this was because it was a

beginner-level project, matching my skills and experience.

Doors are just rectangles with hinges and a few screws,

right? Wrong. Very, very wrong.

It turns out that hanging a door properly is far more

complicated than it looks. You might know this, but the

frame must be measured perfectly. The door has to be

level, or it won’t swing correctly. And the hinges must be

positioned precisely.

Here’s what I learned: if you rush the job, the door won’t

work. It might even look fine, but over time it will sag, stick,

refuse to latch or open. And so, we worked and reworked

until it swung true. I was absurdly proud of that front door.

But it isn’t the carpentry I most remember from that

spring break. What sticks with me two decades later are

the homeowners: a mother and her fifteen-year-old son.

Their story was both heartbreaking and hopeful. Escaping

domestic violence, they spent months living in a car, then

the floor of a friend’s apartment. The home we were building

would be the first safe place for that fifteen-year-old to call

his own. His mother worked longer and harder than any of

us volunteers. For me, it was a college service project—a

good way to spend a spring break. For her, it was the way

out. I remember how she made sure that front door opened

and shut just as it had been designed. And I remember how

she made sure the lock worked, too. That physical door

represented a new chapter in a much longer story—years

of knocking on other doors, seeking help, demanding

safety, refusing to give up until she could build something

permanent for her son.

This is a sermon about justice. We all know that word is

fractured right now. It is contested, and it is weaponized.

To some, it means restoring a kind of order. For others, it

captures the call to turn the system upside down. It inspires,

and it threatens.

But the justice we pursue this morning must transcend

our tribal loyalty. It is the uncompromising vision we find in

Deuteronomy’s law and in the gospels, where Jesus centers

the persistence of one woman demanding what is right.

This is a sermon about prayer. This is a sermon about faith

that keeps knocking, about hope that will not give up.

Jesus told a story so that his disciples would remember

to pray always and not to lose heart, to persistently

petition God with hopeful hearts. At least, that’s how Luke

introduces the parable, which is why the story itself might

unsettle us when we hear it for the first time. It’s a short

story. There are only two characters. There is an unjust

judge—that’s all we know about the judge. He fears neither

God nor humans. And there is a widow seeking justice. How

are we to interpret this parable?

Is Jesus comparing God to an unjust judge? Are our prayers

being reduced to desperate pleading? Must we beg God to

listen to our righteous requests?

You have to read the parable through the lens of Luke’s

gospel. From beginning to end, Luke’s story centers those

pushed to the margins. His picture of God’s kingdom

begins at the back of the line. In this story, Jesus is using

a common rabbinical technique, known in Hebrew as

kal v’chomer. It’s the logic behind the rhetorical question:

how much more? If human injustice yields to relentless

persistence, how much more will God’s justice respond

to our call? In other words, divine justice is infinitely

more responsive. The text asserts God’s eagerness, not

reluctance. I want you to keep that in mind.

Of course, the hero of this story is the widow. Suffice to say,

that alone would have gotten the attention of an ancient

audience. The Greek word for widow is chera, which means

literally bereft. To be a widow is to be a woman without.

Without a husband, yes, but also without protection,

without income, without a voice in the public square or

even in the courts. Yet here she is, demanding what the

law guaranteed but common practice ignored. She keeps

coming back. She keeps knocking, though she has no

power. She embodies hope that will not give up.

Knocking on the door of power and demanding justice—not

charity, not pity, not a handout—justice. What is rightfully hers.

And that, I think, is what makes her prayer so potent, so

dangerous: she’s not praying that God would grant her

patience to endure injustice. She’s demanding what she

deserves—and right now.

I think the persistent widow shines light on a truth we

often miss. You may have noticed that whenever tragedy

strikes, we immediately hear competing, distinct voices:

some of those voices lift up “thoughts and prayers” while

others demand “action now.” But the widow refuses this

false choice. In her words and in her actions, she shows

that prayer without work is hollow, but work without prayer

burns out. Her activism is prayerful, and her prayers compel

action. The two are threads of the same fabric, woven

together in her life of faith.

She doesn’t just annoy the judge with her persistence. She

threatens him, the one thing he values: his reputation. The

Greek here suggests she’s giving him a public black eye. In

other words, she is shining a scorching light on his injustice.

Persistent prayer turns petition to mission. To pray as Jesus

teaches us is to let our lives become the Spirit’s answer.

Action depends on prayer. It roots our work in God’s justice,

rather than our own strength. It sustains us when quick

victories do not come. Prayer grounds us in God’s power.

We have seen testimony of this truth right here.

In just a few moments, as we do every single Sunday, we

will pray, “Give us this day our daily bread.” That petition is

also a summons. What we ask for ourselves, we also ask

for all who lack it. And so, that prayer does not cease at

the benediction. Once you have prayed for daily bread, you

cannot ignore hunger in your community. That’s why, three

days a week, neighbors receive a warm welcome, bags of

groceries, hygiene supplies, and household necessities right

here in this building—850 families every month. Daily bread.

But we also know that daily bread is more than groceries. If

charity feeds hungry bodies, justice asks why our neighbors

are hungry.

We pray for those who lack daily bread, and then we work

to change the conditions that keep some hungry. Right here

in Washington Township, half of public-school students

rely on free lunch. In the Crooked Creek neighborhood,

41% of families are below the level of poverty—a reminder

that neighbors close to home are struggling. That’s why we

launched the Thriving Families Initiative: building cross-

class community so economic mobility can grow through

relationships, not just service.

The question is not whether we should pray. The question

is whether our prayers move us toward places of pain. The

question is whether our prayers transform us, make us

bolder in our faith.

This is a house of prayer. Here we ask God for peace and

healing, for reconciliation and justice. But will those prayers

change us? Will they make us as persistent as the widow?

Will they drive us to keep knocking on doors that must open?

Jesus closes this story with an ominous, probing question.

When the Son of Man comes, will he find faith on earth?

Will faith persist until his return, or will it be crushed by

indifference and cruelty? Will he find faith on earth? I hear

the voice of Jesus in our own time.

Will I find churches that pray for peace and then work to

end violence? Will I find disciples who pray for reconciliation

and then build bridges? Will I find communities who pray

for the hungry and advocate to end poverty? Will I find

believers who pray for their neighbors and then welcome

the anxious stranger? Will I find faith that knocks on the

doors of injustice until they open? Will I find faith that

refuses to lose heart?

No, the widow didn’t have any power. She had something

much mightier. She knew the Word of God that says,

“Pursue justice.” Justice shalt thou pursue. And she did. She

refused to accept her oppression as a permanent condition.

And I think Jesus is looking for disciples who pray like her. I

think God is waiting for a church that prays like that.

Do you remember the promise tucked inside this tough

little story? God is not the unjust judge. How much more

will God—who knows your name and hears your cry—grant

justice to all who put their lives on the line in prayer?

Friends, God is eager to answer prayers that compel our

action. So don’t you dare stop knocking.

Knock for the child who goes to school hungry. Knock

for the elderly couple choosing between medicine and

groceries. Knock for the families trembling at borders and

those grieving inexplicable loss. Knock for the veteran

sleeping on the street and the mother escaping violence in

her own home. Knock for a nation in need of reconciliation

that only prayer makes possible. Knock for the soul of a

nation spiraling toward self-destruction. Knock for your own

soul seeking salvation from the snare of evil.

Keep knocking until your knuckles are bare. Keep praying

until your voice is sore. The doors of injustice are strong, but

faith is stronger. And God, the God of justice, is eager to turn

the latch.

Pray with me: Holy One, make us persistent in our petition

and audacious in our action. Ground our words and our

deeds in your justice. Amen.
