The Most Overlooked Test of Salvation in the Entire Bible

Mud-covered human hand reaching upward from a dark pit, symbolizing desperation and the cry for rescue.

The pit smelled like rot. Not just of earth and clay, but something deeper—something spiritual, something final.

You couldn’t see the top. You couldn’t climb. Every time you moved, you sank. Your feet slipped in the sludge of guilt. Your hands clawed upward only to find more of the same—mud, silence, fear. And when your voice finally broke through the shadows, all you could do was wait. Wait and cry. Wait and hope that Someone was listening.

David remembers that place.

And every real believer does too.

“He brought me up also out of an horrible pit, out of the miry clay, and set my feet upon a rock…” (Psalm 40:2)

This isn’t poetry. This is a rescue report. This is a man who nearly drowned in himself—and was pulled up by a hand not his own.

The Language of the Rescued

David speaks with the breath of someone who has been resuscitated. His voice cracks with memory. This is not ceremony. It is survival.

“I waited patiently for the LORD; and he inclined unto me, and heard my cry.” (v. 1)

Notice what he does not say. He does not say, “I figured it out.” He does not boast of a ladder he built or a prayer he perfected. He simply cried. And waited. And God leaned in.

That’s the first sign someone has truly been saved—they’ve given up on saving themselves.

Many churchgoers can mimic the vocabulary of Christianity. But when a man like David speaks, you hear something different. Something heavy. Something earned in the shadows. A real believer’s testimony isn’t polished—it’s splattered with the memory of where he was when grace found him.

Counterfeit Tongues in the Congregation

Psalm 40 draws a hard line through the congregation. And not the way most expect.

It’s not between the churched and the unchurched, the loud worshipers and the reserved ones, the casual and the committed. No, the dividing line here is deeper. It’s between those who speak the language of rescue—and those who do not.

There is a kind of counterfeit Christianity that’s fluent in clichés but silent on sin. It’s always positive, always polished, always safe. It offers comfort without conviction, heaven without the horror of hell. It sings songs but has never cried from the bottom of a pit.

Psalm 40 has no room for such religion.

David says plainly, “Many shall see it, and fear, and shall trust in the LORD.” (v. 3)

This is not private, internalized, quiet faith. This is visible transformation. The kind you can’t fake. The kind that makes people tremble.

He doesn’t just say God rescued me. He says people saw it. And in seeing it, they too turned to God.

So the question presses itself against our hearts: Can anyone see you’ve been rescued?

A Savior Who Spoke First

In verses 6–10, something remarkable happens.

The voice shifts. The story lifts its eyes.

These words, though written by David, are borrowed by another. Hebrews 10 tells us that what we read here are the very words of Jesus Christ, spoken to His Father before He stepped into flesh and bone.

“Sacrifice and offering thou didst not desire; mine ears hast thou opened… Then said I, Lo, I come… I delight to do thy will, O my God.” (Psalm 40:6–8)

The psalm that begins in the pit now ascends to the throne. From the cry of a man to the mission of the Messiah.

The Old Testament is littered with blood—bulls, goats, lambs. Rivers of it. But none of it could truly cleanse. None of it satisfied the holy ache in God’s heart for justice and mercy to meet.

So Christ came—not reluctantly, but delightedly.

His ears were pierced not by ceremony, but by surrender. Like the willing servant in Exodus whose ear was driven through with an awl to declare, “I will serve my master forever.”

Jesus came, not to play a role, but to fulfill a mission written in eternity: “In the volume of the book it is written of me.”

And He did not hide. He did not whisper. He preached righteousness “in the great congregation.” (v. 9)

His life, His death, His resurrection—it was all declared, not behind curtains, but in blood and wind and open graves.

The Strange Emotions of the Redeemed

By verse 11, David’s tone shifts again. The memory of rescue doesn’t erase the ache of remaining sin.

“Mine iniquities have taken hold upon me, so that I am not able to look up…” (v. 12)

This is not backsliding. This is Christian maturity.

A counterfeit faith may claim perfection. A real believer sees more sin now than ever before—not because there’s more of it, but because his eyes have finally adjusted to the light.

He’s out of the pit. But he still prays like a man who knows he could not last a moment without grace.

This is one of the strangest realities of Christian faith: joy and trembling never separate.

Like Paul, the believer lives as one who is “sorrowful, yet always rejoicing.” (2 Corinthians 6:10) He’s forgiven—and yet freshly wounded by his own frailty. He’s secure—and yet pleads: “Be pleased, O LORD, to deliver me… make haste to help me.” (v. 13)

When the World Mocks Holiness

David is not only battling internal sin. He’s under fire from external enemies.

And here the Psalm takes a sharp turn. It names the mockers. The sneerers. The ones who look at a faithful man and say with curled lips, “Aha, aha.” (v. 15)

You know them. Maybe you work with them. Maybe you live with them. Maybe you used to be them.

They don’t engage with your theology. They don’t wrestle with your arguments. They simply mock. Roll their eyes. Laugh at your restraint. Dismiss your joy.

David doesn’t ask God to help him win an argument. He asks God to shut their mouths.

“Let them be ashamed and confounded… Let them be desolate…” (v. 14–15)

Harsh words? Maybe. But understand this: David isn’t asking for revenge. He’s asking for the scorning of holiness to end. For righteousness to no longer be mocked.

The Christian, like Paul, prays for his enemies to be converted. But if they will not repent, he prays that God will defend His name, defend His people, and silence the mouths that slander what is sacred.

The Last Sentence: A Psalm in One Line

And then, with all the weight of memory and hope, David ends like this:

“I am poor and needy; yet the LORD thinketh upon me.” (v. 17)

That’s it.

That’s the language of the saved. Six words that summarize everything.

I am poor. No strength of my own. No confidence in the flesh.

I am needy. I cannot survive a day without help.

Yet the Lord thinks of me. The Maker of stars and cells, of oceans and orphans, of thunder and tears—He thinks of me.

If your theology doesn’t land here, it isn’t Christian theology. If your heart doesn’t cry this, it hasn’t been broken and remade.

Do You Speak This Way?

Let’s ask it plainly.

When David speaks, do you recognize the dialect?

Have you known the pit—not as metaphor, but as memory?

Have you cried, not to impress, but because there was no one else to cry to?

Have your feet been lifted?

Have your prayers changed?

Have your enemies sharpened?

Has your heart shifted from “I can do this” to “I am poor and needy”?

And—most of all—can you say, with trembling confidence, “Yet the Lord thinketh upon me”?

Because if not, I beg you: do not walk away from this Psalm unbothered.

Do not settle for a gospel that does not offend you first.

Do not assume that because you sit in church, or lead a group, or behave better than most, you are standing on the Rock.

If you do not speak this language, God may be revealing something far more terrifying than you imagined: you are not yet rescued.

But there is hope. Hope that leans toward the cry. Hope that moves at the sound of your voice. Hope that delights to save.

Cry out.

Wait patiently.

And soon, your mouth too will open, trembling, singing, changed:

“He heard my cry… He brought me up… He set my feet upon a rock…”

If this pierced you, share it. If it comforted you, tell someone. If it awakened you, don’t rest until you cry out to the only One who can pull you out.
