Chapter 16

When You Fall Back

Grace for the lifelong journey of renewal

I want to begin this final chapter where every honest Christian book about transformation eventually has to begin.

You are going to fall back.

I do not mean that as a discouragement. I mean it as a relief. Because most of us, somewhere in the back of our minds while we have been reading a book like this one, have been carrying a quiet, anxious question. Will I be able to keep this up? What happens when I drift? What if, six months from now, I am back where I started?

Let me say this to you, as plainly as I can. You will drift. You will skip the journal. You will not keep up with your Bible reading routine the way you meant to. You will say the wrong thing to your spouse. You will find yourself, on some Tuesday afternoon in March, listening to a voice in your head that you thought you had finally beaten — and there it will be, talking with the same old confidence, as if you had never read a single chapter of this book.

This is normal.

This is, in fact, part of the journey. Not an interruption to the journey. Part of it.

And the entire reason this book ends with a chapter on grace, rather than a chapter on willpower, is because the renewing of your mind was never primarily a project you were going to complete by yourself. It was always going to require someone bigger than you to carry it.

That someone has a name. His name is Jesus. And before we close this book, I want to spend the final chapter making sure you have met Him properly.

Because everything we have talked about in the previous fifteen chapters — the new mindset, the new identity, the renewed thinking, the chrysalis, the wings, the path — all of it rests on a foundation that we have only touched lightly so far. And it is time to lay that foundation properly, before you put the book down.

Why Paul wrote to believers

I want you to notice something about the verse this entire book has been built on.

“Do not conform to the pattern of this world, but be transformed by the renewing of your mind” (Romans 12:2).

Paul is not writing this verse to people who are wondering whether to follow Jesus. He is writing it to people who already do. The letter to the Romans is addressed, in its opening verses, to all in Rome who are loved by God and called to be his holy people (Romans 1:7). The recipients are believers. They are already in. They have already trusted Christ. The renewing of the mind, in its biblical setting, is a Christian journey — a process that begins after a person has come into relationship with Jesus, not before.

This matters for two reasons.

If you are a Christian — if you have already trusted Jesus, given Him your life, received His forgiveness, become His — then everything in this book is for you. The renewal is real. The capacity is in you. The Spirit who raised Christ from the dead is alive in you, and He is the one who actually does the renewing.

But if you are not a Christian — if you have picked up this book because the principles sounded interesting, or because somebody pressed it into your hands, or because the language of renewal spoke to something you have been quietly hungry for — then I want to say something to you with all the warmth I can put into a page of writing.

You are very welcome here. I am genuinely glad you have read this far. And I want you to know that the doorway into everything this book describes is not a technique. It is not a programme. It is not even, in the deepest sense, a book. The doorway is a Person. His name is Jesus. And before you start any journey of renewal, this is the first thing you need to do.

You need to meet Him.

Let me tell you, simply and clearly, what He has done for you.

The gospel, in plain words

The story the Bible tells, from beginning to end, is the story of a God who made the world, made us, was rejected by us, and came after us anyway.

He made the world good. Genesis 1 says that, over and over again. And God saw that it was good. He made it beautiful, abundant, full of life, full of possibility. And He made human beings — you and me — in His own image, to know Him, to walk with Him, to enjoy Him, and to share in His work of cultivating the world He had made.

And we walked away.

The Bible calls this sin. The English word can sound religious and outdated. The reality is much simpler. Sin, at its root, is the deliberate decision of the human heart to be its own god rather than to trust God. To run the show ourselves. To define right and wrong on our own terms. To live as if God does not matter and we know better. It is not, primarily, a list of bad behaviours. It is the heart-level decision underneath the behaviours. And the Bible says, with brutal honesty, that every human being who has ever lived has made it. All have sinned and fall short of the glory of God (Romans 3:23).

The consequences of that decision run deep. Sin separates us from God, who is the source of all life. It fractures our relationships with each other. It distorts the way we see ourselves. It infects every corner of the world we live in. And ultimately, the Bible says, the wages of sin is death (Romans 6:23) — both the physical death we all face and a deeper, eternal separation from the God who made us. This is the bad news that the good news of the gospel comes to answer.

Because here is what God did.

He did not abandon us. He did not write us off. He did not say they made their choice; let them live with it. He did something so staggering that two thousand years later we still struggle to take it in.

He came after us Himself.

The Bible calls Him Jesus. In the beginning was the Word, and the Word was with God, and the Word was God… The Word became flesh and made his dwelling among us (John 1:1, 14). God Himself, in the person of His Son, stepped into the world He had made. He took on a human body. He was born in a stable in Bethlehem. He grew up in a working-class town. He lived an ordinary, observable human life — and an extraordinary one. He healed the sick. He fed the hungry. He forgave sinners. He told the truth about God and about us, with a clarity and tenderness no-one before or since has matched.

And then He did what He came to do.

He went to a cross.

The cross is, in many ways, the strangest thing at the centre of the Christian faith. A first-century Roman execution device, the most shameful and brutal punishment the ancient world could devise — and Christians wear it around their necks. We have grown so used to the symbol that we have lost some of the shock of it. But the cross is where everything we have just described — the sin, the separation, the death — was dealt with. Jesus, who had no sin of His own, took upon Himself the sin of the world. He himself bore our sins in his body on the cross (1 Peter 2:24). God made him who had no sin to be sin for us, so that in him we might become the righteousness of God (2 Corinthians 5:21).

What this means, in plain language, is this. The penalty that should have been ours, He took. The death that should have separated us from God forever, He died. He stood in our place. He carried what we could not carry. And His last words on the cross were three of the most important words in human history: It is finished(John 19:30). The Greek word He used — tetelestai — was a word used in the marketplaces of the ancient world when a debt was fully paid. Paid in full. That is what He said about the debt of sin between us and God.

And three days later, He rose.

This is not a metaphor. This is not a nice spiritual idea. The earliest Christians staked their lives on the historical reality that Jesus, who had been crucified, was found alive three days later. He appeared to His disciples. He ate with them. He walked with them. He spent forty days with them before ascending to be with the Father, with the promise that He would one day return.

The resurrection is the great vindication. It is God saying — the price has been accepted. The debt has been paid. Death has been defeated. The way home is open.

This is the good news. God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life (John 3:16).

This is what Jesus has done for you.

How to come home

If, reading this, you find something stirring in you — a sense that this is true, that you have been wandering, that you want to come home — then I want to tell you something simple.

You can.

The Bible says, if you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved (Romans 10:9). It is that simple. It is that accessible. There is no waiting list. There is no qualifying exam. There is no level of cleanness you have to reach before you walk through the door. Jesus has already done everything that needed to be done. All that remains is for you to receive Him.

If that is where you are, let me invite you to pray something with me. Out loud, if you can. In your own room. Wherever you happen to be reading this.

Lord Jesus, I come to you today. I admit that I have lived my life on my own terms, and I have fallen short of who you made me to be. I believe that you came into the world for me. I believe that you died on the cross to take my sin away. I believe that God raised you from the dead. Today, I turn from my old way of living, and I receive you as my Saviour and my Lord. Come into my life. Forgive me. Make me new. Thank you for loving me. I belong to you now. In your name, amen.

If you have just prayed that prayer, even quietly, even shakily, even uncertain whether you said the words right — I want to say to you, with everything I am, welcome home. Heaven is rejoicing over you right now. Find a Bible-believing church. Tell someone what you have just done. Begin the journey we have been describing in this book, because now you actually can.

For everyone else — for the readers who have been Christians for a long time — let me say a final word.

This is where the renewing of the mind has always been heading. Christ in you, the hope of glory (Colossians 1:27). Not you reaching up to God. God reaching down to you. Not you climbing toward heaven. Heaven coming to meet you. Not you trying harder. Christ being formed in you. The whole project rests, from beginning to end, on what He has already done.

Which is why grace is the only place this book can responsibly end.

What grace actually is

Let me tell you, plainly, what grace is.

Grace is the unearned favour of God toward people who could never earn it.

It is the doorway in. It is the foundation underneath. And — and this is the bit most of us miss — it is also the fuel for the journey.

We tend to think of grace as the thing that gets us in. We trust Jesus, we receive grace, we are forgiven, we are welcomed into God’s family — and from there, somehow, we are expected to carry on by our own effort. This is one of the great misunderstandings of the Christian life, and it has produced more burned-out, exhausted, secretly disappointed believers than almost any other error.

Grace is not just the doorway in. Grace is what carries you the whole way home.

Paul knew this. He wrote, in one of his most personal letters, by the grace of God I am what I am, and his grace to me was not without effect. No, I worked harder than all of them — yet not I, but the grace of God that was with me (1 Corinthians 15:10). Read that twice. I worked harder than all of them. Yet not I, but the grace of God that was with me. Paul is not bragging. He is explaining the mechanism. The work was real. He genuinely worked hard. But the source, the strength, the energy underneath the work — was grace.

That is what grace does. Grace is the empowering presence of God in the life of a believer. It is what gets you up in the morning when you do not feel like getting up. It is what keeps you walking the renewal path when you cannot remember why you started. It is what brings the truth back to your mind on the days you would have forgotten it. It is what makes the Bible “come alive” on the morning it would have felt dead. It is the Holy Spirit in you, doing what only the Holy Spirit can do.

You are not the engine of your own renewal.

The Holy Spirit is.

You are the willing participant. He is the One who does the work. And when you stumble — when you fall back, when you forget, when you find yourself once again in the place you thought you had escaped — grace is what is already there, waiting, before you even get up.

What grace looks like when you fall

Let me say something specific to those of you who have already fallen back.

You picked up this book. You started to feel something stir in you. You began to walk the renewal path. And then, somewhere in the middle of it all, you fell. You went back to the old thinking. You picked up the old habit. You hurt the person you promised you would treat better. You found yourself reaching for your old comfort mechanisms — the screen, the food, the things that are just not helpful, the things you know in your heart God does not want for you. You went silent on God for weeks.

You know who you are.

Hear me. Grace is still here.

The most famous story Jesus ever told — the parable of the prodigal son (Luke 15) — is, in the end, about exactly this. A son walks away. He takes his inheritance. He blows it on a life his father would never have approved of. He ends up feeding pigs in a foreign country, hungrier than the pigs themselves. He decides, in desperation, to go home — not as a son, because he has forfeited that right, but as a hired servant, hoping at least to be fed.

He never gets to finish his prepared speech.

The father has been waiting. The father sees him while he is still a long way off. The father runs to him — and ancient fathers in that culture did not run; running was considered undignified — but this father runs anyway, runs to his returning son, throws his arms around him, kisses him, and before the boy can even get out the words make me one of your servants, the father is calling for the best robe, a ring, sandals, a feast.

That is grace.

That is what God is like.

If you have fallen, you have not fallen out of His love. You have not used up His patience. You have not finally proved that you are the one He cannot help. You have, in fact, simply discovered for yourself what every believer eventually discovers — that we do not pull this off on our own, and we were never expected to.

Get up. Come back to Him. Not through penance. Not through performance. Not through a thousand promises that this time you will do better. Simply come. He is already running to meet you.

Resilience comes from grace, not from grit

I want to add one more thing before we close, because in the leadership world there is a great deal of talk about resilience, and most of it is unhelpful for the Christian life.

The world’s resilience is about grit. About refusing to quit. About powering through. About a kind of personal toughness that is admired in business books and motivational talks. There is some truth in it. Perseverance matters. The Bible commends it.

But the resilience of the renewed mind is something different. It is not grit. It is grace-fuelled endurance. It is the long, slow, sustained capacity to keep walking — not because you are strong, but because the One walking with you is.

Paul wrote, when he was suffering in a way he could not bear, my grace is sufficient for you, for my power is made perfect in weakness (2 Corinthians 12:9). Notice what God did not say. He did not say toughen up. He did not say try harder. He did not say you’ve got this. He said my grace is enough. And Paul, in response, said something that should be tattooed on every tired Christian’s heart. Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me.

The resilience that lasts a lifetime is not built out of grit. It is built out of learning, again and again, to lean into grace.

You will not finish this journey by becoming a stronger version of yourself. You will finish it by becoming a more dependent version of yourself — dependent on the One who has been carrying you the whole way.

A final word from one traveller to another

We have come a long way together, you and I.

I have not always known what you needed to hear. I have, in places, written more confidently than I felt. I have leaned on books I have loved, on Scriptures that have held me, on conversations with people who have walked things I have only watched from a distance. But I have written everything in this book in good faith, because the truth in it has carried me, and I genuinely believe it will carry you.

If there is one sentence I want you to leave this book with, it is this.

You are loved.

You are loved by a God who knows everything about you, who has watched every minute of the life you have lived, who has seen every thought you have thought, and who loves you anyway. You are loved with a love that does not depend on your performance. You are loved with a love that has already cost Him everything. You are loved by Someone who is more committed to your renewal than you will ever be.

The renewing of your mind is not, in the end, your project.

It is His.

And He is very good at what He does.

Go now. Walk the path. Fall, get back up, keep walking. Believe what He says about you. Speak the truth back to your soul. Meditate on His Word. Spend time with Him. Forgive the people who hurt you. Love the people He has put around you. Pursue the vision He has placed in you. And when you fall back — and you will fall back — let grace lift you again.

The God who began this good work in you will carry it on to completion until the day of Christ Jesus (Philippians 1:6).

That is my prayer for you.

That is my prayer for me.

That is the renewed life.

Personal reflection

•       Have you, in your own heart, ever made the decision to trust Jesus and receive Him as your Saviour and Lord? If not, what is keeping you?

•       If you have fallen back somewhere on the journey, what is one small step you could take, today, to come home?

•       Where in your Christian life have you been trying to live by grit rather than by grace?

•       Who is one person you could share this gospel with, in your own words, in the coming weeks?

•       As you close this book, what is the one truth you most want to carry forward into your daily life?

A final prayer

Lord Jesus, thank you for everything you have done for me. Thank you for the cross, where you paid what I could never pay. Thank you for the resurrection, where you opened the way home. Thank you for your Spirit, who lives in me and renews me. Lord, I cannot do this on my own. I do not want to do this on my own. Carry me. Renew me. Be patient with me when I fall. Lift me when I stumble. Walk with me all the way home. And let the renewing of my mind be the slow, faithful work of your grace in me, for the rest of my days. In your name I pray, amen.
