Unearned Grace; Isaiah 55:1-9

Opening: The Feast of Unearned Grace

1.1 The word redemption is familiar to us. When we go to a store like Walmart or Superstore, they ask us if we want to redeem our points. We've earned them — one purchase at a time, one payment at a time — and now we can finally cash them in. That's how redemption works in our everyday world: it is entirely merit-based. You get out only what you first put in.

1.2 I confess there was a season in my ministry when I brought that same logic into my walk with God without realizing it. I had prayed hard, given sacrificially, poured myself into the work — and somewhere underneath it all, a quiet calculation was running: If I do this much, God owes me this much stability. This much peace. This much blessing. I was treating grace like a point balance — as if I were accumulating credit I could one day redeem.

1.3 But here's what stops me: in the Bible, redemption doesn't work that way at all. It isn't based on what we've accumulated. It is based entirely on God's decision and God's plan. The grace of God is not a rewards program — it is not something we earn our way toward. It is something given. So here's the question I want us to sit with this morning, not answer too quickly:

Why do we naturally believe that nothing in this life — especially our standing before God — is truly free?

1.4 I don't have a tidy answer for that yet. But I want us to hold that question for a few minutes before we rush toward a solution — because Isaiah 55 is about to interrupt it in a way none of us expect.

Isaiah 55:1–9 ESV

“Come, everyone who thirsts, come to the waters; and he who has no money, come, buy and eat! Come, buy wine and milk without money and without price. Why do you spend your money for that which is not bread, and your labor for that which does not satisfy? Listen diligently to me, and eat what is good, and delight yourselves in rich food. Incline your ear, and come to me; hear, that your soul may live; and I will make with you an everlasting covenant, my steadfast, sure love for David.
Behold, I made him a witness to the peoples, a leader and commander for the peoples. Behold, you shall call a nation that you do not know, and a nation that did not know you shall run to you, because of the Lord your God, and of the Holy One of Israel, for he has glorified you.
“Seek the Lord while he may be found; call upon him while he is near; let the wicked forsake his way, and the unrighteous man his thoughts; let him return to the Lord, that he may have compassion on him, and to our God, for he will abundantly pardon.
For my thoughts are not your thoughts, neither are your ways my ways, declares the Lord. For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts.

Phenomenological Description

2.1 Look at how this passage opens: "Hôi"—"Ho!" In Hebrew, this word is a profound paradox. Throughout the Old Testament, it almost always appears as a cry of judgment, a funeral lament, or a heavy "woe" pronounced over sin and impending disaster. But here, Isaiah takes this very word of mourning and flips it completely. Instead of a declaration of doom, it becomes a passionate, grace-filled summons: "Ho! Come!" The word we would expect to introduce condemnation instead introduces an extravagant invitation.

2.2 Charles Spurgeon beautifully captured the staggering heart behind this cry, noting that in calling out "Ho!", the Almighty God essentially "becomes a beggar to his own creature" . Think about the sheer condescension of this: the Creator of the universe is not demanding payment or issuing a divine subpoena; He is standing like a street vendor, pleading with bankrupt rebels to come to His table. Before God says a single word about what we owe, He is already calling out to us with the urgent, aching heart of a Father.

2.3 And notice how He calls: Come, buy, eat, listen, delight, incline, hear. Seven imperatives, stacked one after another, almost breathless. This isn't a quiet suggestion or a theological proposition to consider at your leisure — it's an urgent, active summons. God isn't inviting us into an idea. He's inviting us into a place, a table, an experience.

2.4 Now picture who first heard this. The exiles in Babylon weren't struggling with abstract theology — they were exhausted, working day after day just to survive in someone else's economy, buying bread that never truly filled them. Into that grinding, transactional system, God says: "Buy wine and milk without money and without price." Not discounted. Not on credit. Free. He's not offering them a better deal inside Babylon's economy — He's inviting them out of that economy altogether, into one that runs on entirely different rules. This is the economy of Grace. It is the upside-down Kingdom that does not match the contemporary world. In our world, paying for what we receive is simply how things work — it's the natural order. But God says we can have it without money. From the world's perspective, that isn't just generous. It's backward.

2.5 Then in verse 3, He goes further: "my steadfast, sure love for David." This was a promise originally made to one king, one royal line. But here God takes that personal covenant and hands it to the whole exiled community — ordinary, defeated, displaced people. What was once reserved for a king now belongs to them. And Paul later picks up this exact phrase in Acts 13:34, tying it to the resurrection of Jesus; Hebrews 13:20 calls it an "everlasting covenant" as well. 

Acts 13:34 ESV

And as for the fact that he raised him from the dead, no more to return to corruption, he has spoken in this way, “ ‘I will give you the holy and sure blessings of David.’

Hebrews 13:20 ESV

Now may the God of peace who brought again from the dead our Lord Jesus, the great shepherd of the sheep, by the blood of the eternal covenant,

The promise made to David doesn't stay locked in the past — it opens outward, eventually to us.

2.6 Verses 6–7 name what our response looks like: "let the wicked forsake his way... let him return (šûb) to the Lord." This isn't just feeling bad about our mistakes. Šûb means an actual turning — a change of direction, body and mind together. And it's paired with dāraš — "seek." Not a passive apology, but an active pursuit of God while He is near. Repentance here isn't groveling; it's turning our whole selves away from self-reliance and walking toward Him. So repentance is a radical change of our life's direction — from ourselves to God.

2.7 And then the passage grounds all of this in verses 8–9: "For my thoughts are not your thoughts, neither are your ways my ways... as the heavens are higher than the earth, so are my ways higher than your ways." This isn't God flexing His power over us. It's God explaining why unearned grace is even possible. Our ways run on merit and repayment. His ways run on abundant pardon — a pardon so generous it doesn't fit inside our categories of fairness. The distance between His thoughts and ours isn't a wall keeping us out; it's the very reason the door is open.

Hermeneutical Circulation

3.1 So this text doesn't stay in Babylon, and it doesn't stay in the 6th century BC. It walks straight into this room, this morning, and it doesn't speak to all of us the same way. Depending on where you're sitting in your life right now, this passage is going to land very differently.

3.2 To the spiritually exhausted — maybe you've been running on the treadmill of perfectionism. More devotion time, more service, more effort, hoping it finally adds up to enough. To you, this text doesn't ask "Are you doing enough?" It asks something else entirely: "Why do you spend your money for that which is not bread?" You're not being called to try harder. You're being called to stop buying what was never going to satisfy you in the first place.

3.3 And here's the deeper issue: it isn't about offering more. It isn't about giving God more of your time, your service, your things. Our spiritual exhaustion is rooted in our own willing and our own desire — we keep trying to fix it by our own effort, from our own perspective, rather than fixing our eyes on God and His perspective. That's precisely why we stay exhausted. And that's why we can't fully receive Jesus' invitation to rest:

Matthew 11:28 NLT

Then Jesus said, “Come to me, all of you who are weary and carry heavy burdens, and I will give you rest.

3.4 Being perfected was never God's calling for us. God isn't asking for our perfection — He's inviting us into a deeper relationship with Him, one where we can finally rest in Him instead of striving before Him.

3.5 To the cynical, the skeptical — maybe you've been burned by church before. Institutions that asked for your money, your time, your loyalty, and gave you conditions in return. To you, this text isn't another sales pitch dressed up in spiritual language. God isn't asking you to trust a system. He's bypassing the whole transactional structure and offering you an everlasting covenant rooted in nothing but His own faithfulness — ḥesed that doesn't depend on the institution getting it right.

3.6 And this is worth naming honestly: when we serve God, we sometimes fall into the same misunderstanding those institutions did — believing that our outward activity is what makes the church grow. That's partly true. But before we do the outward work, we need to examine our faith and our inner heart first. Action without a right heart is meaningless. And action driven by our own expectations of what God should do isn't God's work at all — it's just the same transactional logic, wearing church clothes.

3.7 To the self-righteous, the calculative — maybe you're not exhausted or cynical at all. Maybe you're doing quite well by your own scorecard. You pray, you give, you serve, and you know it. To you, verses 8–9 are the most unsettling part of this whole passage: "my thoughts are not your thoughts." God's higher ways don't just forgive the people who've failed — they dismantle the very scorecard you've been keeping. Repentance for you isn't just turning from wrongdoing; it's turning from your own bookkeeping.

3.8 To the community on mission — remember verse 5: "you shall call a nation that you do not know, and a nation that did not know you shall run to you." This restored, undeserving community doesn't just receive grace and keep it. They become the very place the nations run to. If you've received this unearned feast, you're not meant to guard the table — you're meant to set more places at it.

3.9 Four very different postures, one and the same invitation. That's what makes this "Ho! Come!" so different from anything Babylon — or our own hearts — ever offer.

Impression (The Retained Perspective)

4.1 Isaiah 55 doesn't end in the 6th century BC, and it doesn't end this morning either. Centuries later, at the very close of Scripture, we hear the same invitation echo one more time:

Revelation 22:17 NIV

The Spirit and the bride say, “Come!” And let the one who hears say, “Come!” Let the one who is thirsty come; and let the one who wishes take the free gift of the water of life.

4.2 The same call. The same word — come. The same "without price." What began as a word to exhausted exiles in Babylon becomes the final word of the entire Bible: an open invitation, still standing, still free, all the way to the end of the story.

 But we need to be careful here — "free" and "without price" don't mean "without cost." They mean the cost was never ours to pay.

4.3 Turn back just two chapters, to Isaiah 53 — the very passage that comes right before this one. There we read of a suffering servant who was "pierced for our transgressions," "crushed for our iniquities," the one "upon whom was the chastisement that brought us peace." Isaiah placed these two chapters side by side on purpose. Chapter 53 is where the price gets paid. Chapter 55 is where the invitation goes out. The reason we can come and buy wine and milk without money is that Someone else already paid in full — not with silver, but with His own life.

4.4 This is why Paul can say we were "bought with a price" (1 Corinthians 6:20), and why Peter says we were redeemed "not with perishable things such as silver or gold... but with the precious blood of Christ" (1 Peter 1:18–19). The table is free to us. It was not free to Him.

1 Corinthians 6:20 NRSV

For you were bought with a price; therefore glorify God in your body.

1 Peter 1:18–19 ESV

knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold, but with the precious blood of Christ, like that of a lamb without blemish or spot.

4.5 That's what tells us this was never just a temporary provision for one struggling community. It's who God has always been, from Isaiah's exiles to us this morning to whoever stands at the very last chapter of history. The feast doesn't run out. The invitation doesn't expire. The economy of grace isn't a one-time exception to how God deals with us — it's the ground floor of it. And it stands on the cross, not around it.

4.6 So I don't want to leave you with a three-step plan this morning. I don't want you walking out trying harder to earn what was never for sale in the first place — and I don't want you thinking it cost nothing, either. It cost everything. Just not from you. I just want to leave you with one image to carry through this week:

4.7 Whatever ledger you've been keeping — whether you're exhausted, cynical, self-righteous, or still finding your place in this — that ledger was never what got you a seat at the table. Someone else already settled it. Ho! Come. The table is already set. And it was never about what you brought to it.

Response

5.1 So let me leave you with a few questions to sit with this week — not to solve them right now, but to carry them home with you.

1) If you've been running on the treadmill of perfectionism — where in your life are you still trying to earn what God has already given for free?

2) If you've been burned by transactional religion — can you let this text bypass the institution and speak to you directly, from God's own faithfulness rather than anyone else's failures?

3) If you've been keeping score without realizing it — what would it look like this week to set the ledger down, not because you've balanced it, but because it was never the point?

4) And if you've already tasted this grace — who around you is still buying bread that doesn't satisfy, and how might you set another place at this table for them?

5.2 Four different questions, for four different hearts in this room. But every one of them leads back to the same door.

Conclusion

6.1 The exiles in Babylon didn't walk out of exile because they finally earned enough to leave. They walked out because God said "Ho! Come!" — and that was enough. The same voice is speaking this morning, over whatever ledger you've been keeping, whatever exhaustion or cynicism or quiet self-righteousness you walked in with. The table is already set. The price is already paid. All that's left is to come.
