God Is Doing a New Thing in You

Article 8 of 14   |   Starting Point   |   Isaiah 43:18–19

by Dr. Timothy Mann

God does not merely close the book on your past. He opens a new one. Isaiah 43 moves straight from “I will not remember your sins” to “Behold, I will do a new thing,” which means your Christian life is not damage control. It is genuine forward movement that God Himself produces.

Stop Living in the Former Things

Look at what God says right before He promises to blot out transgressions:

“Do not remember the former things, nor consider the things of old. Behold, I will do a new thing, now it shall spring forth; shall you not know it? I will even make a road in the wilderness and rivers in the desert” (Isaiah 43:18–19).

“Do not remember the former things” is not a command to practice selective amnesia or pretend your history did not happen. It is a command to stop living there. To stop defining yourself by it. To stop letting what is behind you have the final word on who you are and where you are going.

There is a difference between remembering your past honestly and rehearsing it endlessly. The first produces gratitude. The second produces paralysis. One looks back at what God brought you out of. The other keeps you living in the house you were rescued from.

A Road in the Wilderness

Notice the two images God reaches for. A road in the wilderness. Rivers in the desert.

To people living in the ancient Near East, those pictures landed hard. A wilderness was not scenery; it was a place that killed travelers. A desert was not a landscape; it was the absence of the one thing that sustains life. God is saying: I will make a way through what looks impassable, and I will bring life where there is visibly none.

That is what He is doing in you. Not a modest improvement to a life that was basically fine. A road where there was no road. Water where there was only sand. And notice who does it. I will make a road. I will bring rivers. Every verb in that promise belongs to God.

New Creation Is a Present Reality

“If anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new” (2 Corinthians 5:17).

Old things have passed away. That includes the identity your past handed you. You are no longer defined by what you did or by what was done to you. You are defined by what Christ has done for you.

Understand what this is and is not. It is not perfection. Every believer knows the ongoing struggle with sin, and anyone who tells you otherwise is selling something. It is genuine forward movement. Real change, however uneven, in the direction of who God made you to be. And that movement is not something you manufacture by trying harder. It is something the Spirit produces in you.

That distinction matters enormously for how you handle a bad week. If your growth depended on your willpower, a setback would be evidence that the project is failing. Because your growth depends on God’s work in you, a setback is a detour on a road He is still building.

What to Actually Do With Your Past

Acknowledge it honestly. Do not pretend it did not happen or dress it up in softer language.

Bring it fully to God in confession and receive His complete forgiveness rather than negotiating with Him about it.

Then release your grip. Stop rehearsing it. Stop letting it define you. And stop agreeing with the enemy when he brings it up as evidence against you, because God does not bring it up. He has blotted it out. He has cast it into the depths of the sea. He has removed it as far as the east is from the west.

Your past is not your identity. Your identity is in Christ, and that identity is new, and clean, and carrying a future your past cannot touch.

APPLICATION & REFLECTION

Take one area where you have quietly assumed change is not possible for you: an old habit, a pattern in your relationships, a fear you have organized your life around. Name it, and ask God specifically to make a road there.

Then watch for evidence. Keep a short record over the next month of anything that has genuinely shifted, however small. Growth in the Christian life is usually invisible day to day and obvious over a year.

A question worth answering honestly: are you still introducing yourself, in your own mind, by your former things? Bring that to someone in your church who will remind you what is actually true.

FREQUENTLY ASKED QUESTIONS

What does it mean that I’m a new creation in Christ?

It means your fundamental identity has changed, not merely your behavior. 2 Corinthians 5:17 says the old has passed away and all things have become new. You are no longer defined by your past or by your own record, but by union with Christ and by what He has done for you.

If I’m a new creation, why do I still sin?

Because sanctification is progressive. Your standing before God changed instantly at conversion; your character changes over a lifetime. The ongoing struggle with sin is a normal Christian experience and is not evidence that your conversion was false.
