There's something deeply human about the way we cling to what was. We collect memories like precious stones, polishing them until they shine brighter than they perhaps did in real time. We tell ourselves that if we could just recapture that magic from years past, everything would be okay again.

But what happens when our memories become more vivid than our hopes? What happens when we're so busy looking backward that we miss what's unfolding right in front of us?

The Danger of Driving by the Rearview Mirror

Imagine trying to drive a car by looking exclusively in the rearview mirror. Theoretically, you might think it could work—keep the road relatively straight behind you, adjust for curves, and you should stay on track, right?

Of course, it's absurd. You'd have no idea what's ahead, no awareness of obstacles or opportunities. You'd be a danger to yourself and everyone around you.

Yet this is precisely how many of us—and many of our institutions—try to navigate the future. We allow what worked before to dictate what we attempt now. We say "that's how we've always done it" as if those words carry the weight of divine mandate rather than simple habit.

A People Stuck Between Memory and Hope

The prophet Isaiah encountered this very tension among God's people. They were living in—or approaching—exile, a season when everything that once defined them had been stripped away. The land, the temple, the security of their identity—all gone.

In their grief, they did what grieving people always do: they reached back for better days. They held tightly to their formational story, the Exodus from Egypt. It was the narrative that shaped their identity as a people—the dramatic rescue, the parting of the sea, the defeat of Pharaoh's army, the miraculous provision in the wilderness.

God had done it before. Surely God could do it again, in exactly the same way.

Isaiah begins by meeting them in that memory. In Isaiah 43:16-17, he reminds them: "Thus says the LORD, who makes a way in the sea, a path in the mighty waters, who brings out chariot and horse, army and warrior..."

The prophet honors their history. He validates the importance of remembering God's faithfulness. Memory matters. Tradition has value. The stories of what God has done form the foundation of faith.

But then Isaiah does something shocking.

"Do Not Remember the Former Things"

Just after affirming their story, Isaiah delivers one of the most startling commands in all of Scripture: "Do not remember the former things or consider the things of old. I am about to do a new thing; now it springs forth; do you not perceive it? I will make a way in the wilderness and rivers in the desert" (Isaiah 43:18-19).

Wait—don't remember? Didn't we just establish how important the Exodus story was?

Here's the crucial insight: at some point, the Exodus had become a ceiling rather than a floor. What was meant to be the foundation of faith had become the limit of imagination.

The people could only conceive of God working in the way God had worked before. When they didn't see a repeat performance, they assumed God wasn't working at all. Their vision had narrowed to the rearview mirror.

But notice something powerful in verse 16. When Isaiah says God "makes a way in the sea," the verb isn't past tense. It's present, continuous action. The God of the Exodus isn't a historical figure locked in the past. God is actively, presently, continuously at work.

The problem isn't that God has stopped moving. The problem is that the people have stopped seeing.

What Blinds Us to the New Thing?

What causes this kind of spiritual tunnel vision? Several culprits come to mind:

Nostalgia can be a beautiful thing, but it can also become a trap. When our love for how things were interferes with our ability to embrace how things could be, nostalgia has overstayed its welcome.

Fear often masquerades as faithfulness. We're afraid of change, afraid of the discomfort that accompanies new seasons, afraid that different means worse.

Fixed expectations about what God should do leave no room for what God is actually doing. We write the script and then get frustrated when God doesn't follow our stage directions.

Surface-level innovation tempts us to think that a fresh coat of paint on old structures equals transformation. It rarely does.

God's response to all of this? "Look up! Pay attention! Something is already happening. Do you not perceive it?"

Rivers in the Desert

The imagery Isaiah uses is stunning in its reversal. The first Exodus was about making a way through water—the sea parted and Israel walked on dry ground.

But God's new thing isn't a simple rerun. God promises to make a way through the wilderness and provide water in the desert. The categories have been redrawn. The wilderness becomes a place of provision. The desert becomes a source of life.

This is how God works. Every new act of divine faithfulness takes the old patterns and reimagines them. God is endlessly creative, never boring, always doing something fresh while remaining utterly consistent in character.

And the purpose? "The people whom I formed for myself so that they might declare my praise" (Isaiah 43:21).

This isn't about mere survival. It's not about just getting through hard times or maintaining what once was. It's about becoming a people so shaped by God's faithfulness that they can't help but point others toward it.

Perceiving the New Thing

The invitation embedded in Isaiah's prophecy is as relevant now as it was then: Where are you seeing signs of what God is doing?

Maybe it's a conversation that surprised you, opening a door you didn't know existed. Perhaps it's a "chance" encounter that felt anything but random. It could be a relationship that deepened unexpectedly or a moment of clarity that broke through the fog of confusion.

These are rivers in the desert. These are signs of the new thing already springing forth.

The question is whether we have eyes to see them.

Building the Future Together

Isaiah's word wasn't simply "Hang in there, God's got a plan." It was "Get moving, because God is already on the move."

Those who are formed to declare God's praise can't do it from the sidelines. They do it by stepping into what God is already doing and saying, "Count me in."

The future isn't found in the rearview mirror. It's not built by perfectly replicating what worked in another era for different people in different circumstances. The future is built by people who honor their history while keeping their eyes fixed on what God is doing now.

It's built by communities that ask not "How do we preserve what was?" but "How do we participate in what's emerging?"

It's built by individuals who say yes to God's invitation, even when—especially when—it looks different than expected.

The past is a springboard, not a bench. It's meant to propel us forward, not keep us stationary.

So here's the challenge: What new thing is God doing in your life, in your community, in your corner of the world? And more importantly, do you perceive it?

The rivers are already flowing in the desert. The way is already being made in the wilderness.

The only question is whether we'll step into the story being written right now.
