Isaiah 43:19 Meaning: What Does "I Am Doing a New Thing" Really Mean?

"Behold, I will do a new thing" is a verse people reach for at the start of a new year, after a breakup, during a career change, or in any season that feels like an ending giving way to something else. There's good reason for that impulse — the verse genuinely is about newness, restoration, and hope. But Isaiah 43:19 was spoken to a specific people, in a specific historical crisis, about a specific kind of "new thing" — not a general prediction that a new job, relationship, or personal breakthrough is on its way for whoever happens to be reading it.

This article walks through Isaiah 43, especially verses 14–21, to recover what "new thing" originally meant — and to responsibly draw out what Christians today can and cannot take from this promise.

"Behold, I will do a new thing; now it shall spring forth; shall ye not know it? I will even make a way in the wilderness, and rivers in the desert."Isaiah 43:19 · KJV

Quick Answer

Isaiah 43:19 is part of a passage (43:14–21) addressed to Israel, specifically anticipating their return from Babylonian exile. God, identifying himself as Israel's "Redeemer" (43:14), promises to bring down Babylon (43:14) and then, drawing on the memory of the exodus from Egypt — "which maketh a way in the sea, and a path in the mighty waters" (43:16) — announces something new: a second exodus, a way home from exile through the wilderness, complete with provision ("rivers in the desert," 43:19–20) for the journey. Verse 18's instruction, "Remember ye not the former things, neither consider the things of old," does not mean forgetting Israel's entire history (Isaiah elsewhere repeatedly calls Israel to remember God's past faithfulness, e.g., 46:9). In context, it specifically means not clinging to the first exodus as the final, unsurpassable standard, since God is about to do something comparably wondrous — a new exodus, a new act of deliverance for a new moment of need.

This is a powerful promise of God's covenant faithfulness and restoring power, but it is historically rooted in Israel's return from exile, not a generic prediction that a new job, relationship, or personal breakthrough is coming for any modern reader who claims it. Applying the verse responsibly today means first understanding this original restoration context, and then drawing out legitimate, broader Christian principles — about God's faithfulness, his capacity to bring life out of desolation, and his pattern of doing genuinely new things in the lives of his people — without turning a specific prophetic promise into an open-ended guarantee of personal outcomes.

The Story Behind the Verse

Isaiah 43 sits within chapters 40–55, a section of the book widely understood to address Israel either anticipating or already experiencing exile in Babylon (the sixth century BC), offering comfort, a case for God's incomparable power against the idols of Babylon, and promises of eventual restoration. The prophet's task in this section is largely pastoral and theological: convincing a defeated, displaced, and discouraged people that their God has neither abandoned them nor been defeated by Babylon's gods, and that restoration is genuinely coming.

Chapter 43 opens with comfort grounded in Israel's identity and God's ownership of them: "But now thus saith the LORD that created thee, O Jacob, and he that formed thee, O Israel, Fear not: for I have redeemed thee, I have called thee by thy name; thou art mine" (43:1). The chapter continues with promises of God's presence through difficulty — "When thou passest through the waters, I will be with thee" (43:2) — and God's declaration of Israel's identity and purpose: "This people have I formed for myself; they shall shew forth my praise" (43:21, closing the unit relevant to our verse).

Verses 14–21 form a specific sub-unit building toward verse 19. Verse 14 announces judgment on Babylon: "For your sake I have sent to Babylon, and have brought down all their nobles." Verse 15 restates God's identity as "the LORD your Holy One, the creator of Israel, your King." Verses 16–17 recall the first exodus in vivid, specific terms — "Thus saith the LORD, which maketh a way in the sea, and a path in the mighty waters; Which bringeth forth the chariot and horse, the army and the power; they shall lie down together, they shall not rise: they are extinct, they are quenched as tow" — deliberately evoking the crossing of the Red Sea and the defeat of Pharaoh's army (Exodus 14).

Then comes the pivot: "Remember ye not the former things, neither consider the things of old" (43:18) — not erasing this history, but redirecting attention forward, because verse 19 announces: "Behold, I will do a new thing; now it shall spring forth; shall ye not know it? I will even make a way in the wilderness, and rivers in the desert." Verse 20 extends the imagery: "The beast of the field shall honour me, the dragons and the owls: because I give waters in the wilderness, and rivers in the desert, to give drink to my people, my chosen." Verse 21 closes the unit with purpose: "This people have I formed for myself; they shall shew forth my praise."

Historical and Biblical Context

The Babylonian exile. Babylon destroyed Jerusalem and the temple in 586 BC, after earlier deportations, creating the national trauma that forms the horizon of much of Isaiah 40–55. These chapters speak comfort and restoration to Zion and explicitly name Cyrus in Isaiah 44:28–45:1. After Persia conquered Babylon, Cyrus authorized displaced peoples, including Judeans, to return and restore sanctuaries; the first return is conventionally dated to the late 530s BC. The historical setting supports the restoration reading without requiring every detail of Isaiah’s composition history to be settled.

"New exodus" theme. Isaiah 40–55 repeatedly draws on exodus imagery to describe the anticipated return from exile — a pattern scholars often call the "new exodus" motif. This includes a highway through the wilderness (40:3–5; 43:19), water provided in the desert (41:17–20; 43:19–20; 48:21), and God's presence leading his people (52:11–12). The original exodus from Egypt functions as the template and guarantee for this second, greater deliverance: the God who acted decisively once will act decisively again.

"Rivers in the desert" and ancient Near Eastern geography. The imagery of water in a wilderness carries immediate, concrete significance for people whose planned journey home from Babylon to Judah would cross genuinely arid terrain; God's provision of "rivers in the desert" is both a literal, practical promise relevant to the return journey and a rich theological image of abundant, unexpected provision in a barren place.

Important Words and Phrases

"New thing" (Hebrew chadashah, feminine form of "new," possibly implying "a new thing" in a comprehensive or foundational sense). The word describes genuine novelty — not simply a repetition of the past, but something distinct, even while patterned after and guaranteed by God's past faithfulness (the exodus). In context, this "new thing" specifically refers to the return from Babylonian exile and the journey home through the wilderness with divine provision.

"Remember ye not the former things" (43:18). This instruction must be read carefully alongside the rest of Isaiah, which elsewhere explicitly commands Israel to remember God's past acts (46:9, "Remember the former things of old: for I am God, and there is none else"). The apparent tension resolves when read in context: 43:18 is not a blanket command to forget history, but a specific instruction not to treat the first exodus as an unrepeatable, unsurpassable high point that limits expectations for what God can do next. It's forward-orientation, not historical amnesia.

"Shall spring forth" (Hebrew tsamach, "to sprout," "to spring up," often used of plant growth). This agricultural image suggests organic, visible emergence — the new thing is not distant or merely promised in the abstract; it is described as already beginning to appear, "now."

"A way in the wilderness, and rivers in the desert." Direct parallel and echo of the "way in the sea" language used of the first exodus in verse 16, establishing this new deliverance as comparable in scale and character to the original exodus — God making a path where none naturally exists, and providing water where none naturally flows.

The Verse in Its Surrounding Passage

Verse 19 cannot be separated from verses 16–18's deliberate recollection of the exodus, nor from verses 20–21's continuation of the wilderness-provision imagery and statement of purpose ("that they might shew forth my praise"). The whole unit builds a single argument: the God who parted the sea and defeated Pharaoh's army is now announcing a comparable, even more immediate act of deliverance — bringing Israel home from Babylon through the wilderness, providing for their journey, for the ultimate purpose of their praise and witness to who he is. Removing verse 19 from this frame and treating it as an isolated declaration about "newness" in general loses this entire structure of promise-fulfillment-purpose that gives the verse its original force and meaning.

What This Verse Does NOT Mean

It does not mean a new job, relationship, or personal breakthrough is specifically guaranteed to any individual reader who claims this verse. The "new thing" in its original context is a specific historical event — Israel's return from Babylonian exile — not an undefined promise of positive change applicable to any modern personal circumstance.

It does not mean forgetting or erasing your past, in a general therapeutic sense. "Remember ye not the former things" is a specific instruction not to treat the first exodus as limiting expectations for a second deliverance — it is not a general biblical principle about detaching from personal history or trauma, though it can be responsibly and gently connected to broader themes of hope and forward movement in other contexts.

It does not mean your breakthrough is guaranteed, or that God must replace everything you have lost. The promise in Isaiah 43 is specific, covenantal, and historically fulfilled in Israel's return from exile — extrapolating it into a universal law that God owes every person replacement or breakthrough after every loss goes beyond the text's actual claim.

It does not mean the "new thing" happens without ongoing dependence on God. Even within the promise, Israel's journey through the wilderness required continued reliance on God's provision (verses 19–20) — the "new thing" is not self-generated success but a continuation of the same pattern of dependence that marked the original exodus.

How Christians Can Understand This Verse Today

ORIGINAL CONTEXT: God promises exiled Israel a second exodus — deliverance from Babylon and a journey home through the wilderness, provided for by God himself, comparable to and guaranteed by his past act of deliverance from Egypt.

BIBLICAL PRINCIPLE: God is faithful to bring his people through desolation into restoration, capable of doing genuinely new things that are not limited by what he has done before, and his past faithfulness is the pattern and guarantee — not the ceiling — for what he can do in the future.

RESPONSIBLE MODERN APPLICATION: Christians can draw real, legitimate hope from Isaiah 43:19 that God is capable of bringing renewal and restoration out of desolate circumstances, and that his past faithfulness in a person's life is grounds for trusting his ongoing faithfulness, not a limit on it. This is different from treating the verse as a specific prediction of a particular desired outcome — a job, a relationship, a financial turnaround — which the text does not promise to any individual reader.

Real-Life Application

Someone entering a genuinely new season after loss. A person starting over after a divorce, job loss, or major life transition can find real, legitimate encouragement in this verse's theme — that God is not limited to repeating the past, and can bring genuine newness even out of a wilderness season — while being cautious not to treat it as a specific guarantee of a particular desired outcome.

A church community facing decline or difficulty. Just as this promise was originally corporate (addressed to the nation of Israel), it applies meaningfully to church communities navigating decline, conflict, or uncertainty, offering hope for genuine renewal without prescribing its exact form or timing.

Someone using this verse to avoid processing past trauma. If "remember ye not the former things" is used to suggest a person should suppress or avoid dealing with genuine trauma or grief, that use misapplies the verse; healthy healing typically requires honest processing of the past, not denial of it, and this verse's original meaning is about not being limited by past expectations, not about avoiding necessary grief work.

A person waiting for their own "wilderness" season to end. Even within the promise of restoration, the imagery includes wilderness and desert — real, hard terrain that must still be crossed, even with God's provision. This verse doesn't promise instant escape from difficulty, but God's provision and presence within it, on the way toward restoration.

A Deeper Spiritual Lesson

There's something worth noticing in how this promise is structured: the "new thing" doesn't erase the wilderness — it runs straight through it. God doesn't promise to transport Israel from Babylon to Judah instantly, bypassing hardship. He promises "a way in the wilderness, and rivers in the desert" — provision within difficult terrain, not exemption from it. The newness of God's work is displayed precisely in his capacity to sustain his people through desolate territory, not in his removal of that territory altogether.

This has real significance for how the verse should be applied today. A shallow reading treats "I am doing a new thing" as a promise that hardship is ending and comfort is arriving. The text itself resists that shallow reading: the new thing includes wilderness and desert as its very setting. What's new is not the absence of hard terrain, but God's provision and presence within it — a way where there was no way, water where there was no water. This is a considerably more durable, honest kind of hope than a promise of imminent ease, because it doesn't require present circumstances to have already improved in order to be true.

There's also theological weight in the purpose clause that closes the unit: "This people have I formed for myself; they shall shew forth my praise" (43:21). The "new thing" isn't ultimately about Israel's comfort as an end in itself — it's connected to their identity and purpose as a people formed to display God's character to the world. This reframes how any individual believer might responsibly apply the passage: not primarily as a promise oriented toward personal comfort or achievement, but as an invitation to trust that whatever renewal God works — corporately or individually — is ultimately in service of a larger purpose, that God's people would "shew forth" who he is. The "new thing," rightly understood, is never simply about the recipient; it's about what the recipient's restored life then testifies to others about the God who restored them.

Original Prayer

Lord, you are the God who made a way through the sea and who makes a way in the wilderness — not because the wilderness disappears, but because you sustain your people within it. I bring you the desolate places in my own life right now, the seasons that feel like exile, and I ask not for an escape from every hard thing, but for your provision and presence within it. Thank you that your past faithfulness isn't a ceiling on what you can do now — you are capable of genuinely new things, even when I can't yet see how. Help me trust your character rather than demanding a specific outcome, and let whatever renewal you work in me ultimately point back to you, not just to my own comfort. Make a way, Lord, and let my life show forth your praise. Amen.

FAQ

Does Isaiah 43:19 promise a new job, relationship, or personal breakthrough? Not specifically. In its original context, the "new thing" refers to Israel's return from Babylonian exile — a specific historical restoration, not an open-ended personal prediction.

What does "remember ye not the former things" mean? It means not treating the first exodus as an unrepeatable high point that limits expectations for what God can do next — not a general command to forget or suppress your personal history, which Isaiah elsewhere explicitly instructs Israel to remember.

Why does the verse mention a "way in the wilderness" and "rivers in the desert"? This imagery directly parallels and echoes the first exodus (a way through the sea) and reflects the literal geography of the journey home from Babylon to Judah, which required crossing arid wilderness terrain.

Can I still apply this verse to my own life today? Yes, responsibly — as a picture of God's faithful character and capacity to bring genuine renewal out of desolate circumstances, understood as a broader principle drawn from the original historical promise, not as a specific guarantee of a particular personal outcome.

Does this verse mean hardship will disappear once God's "new thing" arrives? No — the promise includes provision within the wilderness and desert, not the removal of that difficult terrain. The newness is God's sustaining presence and provision within hardship, not necessarily an escape from it.

Who is the Servant or figure being addressed in Isaiah 43? Unlike the Servant Songs, this passage addresses the nation of Israel/Jacob directly as God's people, not primarily an individual servant figure.

How does this relate to Revelation 21:5, "Behold, I make all things new"? Revelation 21:5 represents the ultimate, final fulfillment of God's pattern of renewal first displayed in passages like Isaiah 43:19 — a much larger, cosmic "new thing" realized in the new creation.

What's the danger in using this verse as a personal prediction? It can create false expectations or disappointment when a hoped-for specific outcome doesn't materialize, and it can obscure the verse's richer, more durable original meaning about God's faithful character and presence within hardship.
