What if you could call things into existence?
Declare is a battle manual for men who are done spectating — a guide to bringing what God says from the spiritual realm into the physical.
You are in a war you didn't choose. Ignoring it won't save you.
“We are in a spiritual battle, the warfare is real.”
“What you need to understand is that ignoring that battle will not lead to victory, only to demise.”
“The only way to have victory is to stand and fight. That is what declaration is.”
What you speak shapes who you become.
Your words don't just describe reality—they create it. The language you use becomes the lens through which you see your future. When you choose to speak life instead of defeat, you're not just changing your words. You're reprogramming your mind and reshaping your destiny.
This is where declaration begins.
“When you speak God's word, releasing it into the atmosphere and knowing it is true — you will see things change.”
Declaration is bold certainty made manifest.
It's not a question. It's not whispered in doubt. Declaration is a statement of absolute certainty—spoken with conviction, rooted in faith, and backed by the authority God has already given you.
When you declare, you change the spiritual atmosphere.
“Declaration is like blowing the horn of war announcing to the enemy that the battle is beginning.”
You're not just speaking words into the void. You're announcing to the heavens and earth that you believe, that you stand, and that what God says will manifest. That's power.
The Missing Ingredient.
Most men know what they *should* declare. But they don't have the conviction to back it up. They whisper instead of roar. They hope instead of know. That gap between knowing and believing? That's where Declare comes in.
“We can only expect victory in declaration if we have conviction in what we speak.”
It's not about volume. It's about knowing—deep in your gut—that what you speak is backed by the authority of God. And that changes everything.
You carry the authority of heaven.
“As a prodigal returned home you receive protection, provision and authority to do business in Jesus' name.”
You are not a beggar asking God for crumbs. You're a son coming home to your Father's house—and everything in it belongs to you by right. Protection. Provision. Authority.
When you declare from that place of identity, you're not hoping God will act. You know He will.
What you declare takes time to manifest.
Declaration isn't magic. It's not a 10-second fix. It's a process. Like a locomotive building momentum, your words start slow and gain power over time. The stronger your conviction, the faster the momentum. But you have to trust the process.
Don't quit. Don't doubt. Keep declaring what God says, and over time you'll look back and see how far you've come.
“Often Declaration works more like a locomotive than a 10-second car.”
This is the objection you've been waiting for the book to address. Your breakthrough is coming. Stay the course.
Why Declaration Actually Works (And Why So Many Christians Miss It)
From Genesis to Revelation, scripture reveals a consistent pattern: God creates and changes things by speaking. "Let there be light." "Lazarus, come forth." "Peace, be still." When Jesus walked the earth, He didn't just pray about problems — He spoke directly to them. He commanded storms. He cursed fig trees. He declared healing. And He told His disciples they would do "even greater things."
That authority didn't disappear at the cross. It was transferred. Yet most Christian men today live as if the only weapon in their arsenal is a polite, hopeful prayer. They petition heaven for things God has already declared, while the enemy walks unchallenged through their marriages, finances, careers, and families.
The Three Pillars of Effective Declaration
In Declare: Calling the Spiritual into the Physical, Mark Simpson breaks down the practice of biblical declaration into three foundational pillars that every man needs to understand before he opens his mouth:
1. Foundation in Truth
Declaration only works when it's anchored in what God has actually said. You can't declare your way around scripture — you declare what scripture already promises. The book teaches you how to find and own those promises.
2. Conviction in Spirit
Words without belief are noise. The book walks you through how to build the inner certainty — the gut-level "knowing" — that turns spoken words into spiritual force. Without conviction, declaration becomes performance.
3. Authority in Identity
A beggar's words have no weight. A son's words carry his father's name. The book reframes who you are in Christ, so when you speak, you speak from identity — not from desperation. That changes everything.
The Difference Between Praying, Wishing, and Declaring
This is where most men get stuck. They think declaration is just "really intense prayer" or "speaking positively." It's not.
- →Wishing says, "I hope this changes." It's passive, hopeful, and powerless.
- →Praying says, "God, please change this." It's active, faithful, and asks heaven to move.
- →Declaring says, "By the authority of God's word, this will change." It enforces what heaven has already decided.
All three have their place. But Christian men who only know how to wish and pray are leaving the most powerful tool in the toolbox unused. Declare teaches you how to add the third — and how to know which to use when.

Author · Teacher · Believer
Mark Simpson writes for Christian men who are done playing small. After years walking out the principles of declaration in his own life — through marriage, business, parenting, and personal trials — he wrote Declare to put what he learned into the hands of other men.
His writing is direct, biblical, and practical. No fluff. No filler. Just the truth about what God's word can do when men finally start speaking it like they believe it.
Common questions about declaration & the book.
What is declaration in the Bible?+
Biblical declaration is speaking God's word with conviction as a statement of certainty — not a question, not a wish. It's the practice of agreeing with heaven and calling what God has already said into your physical reality. Throughout scripture, God creates, heals, and changes circumstances by speaking. Declaration is the believer doing the same — under His authority and according to His word.
Who is this book written for?+
Declare is written primarily for Christian men — though anyone can benefit from it. It's especially for men who feel stuck spectating their own lives, men who want to step into spiritual authority, and men who want a practical, no-fluff guide to fighting the spiritual battles they're already in. If you've been a passive Christian and you're ready to stand and fight, this book is for you.
Is declaration the same as positive thinking or 'manifesting'?+
No, and this is one of the most important distinctions the book makes. Positive thinking is rooted in your own optimism. 'Manifesting' is rooted in self. Biblical declaration is rooted in God's word and backed by His authority. The power doesn't come from you — it comes from what God has already said. You're not creating reality with your thoughts; you're enforcing what heaven has already decided.
How quickly does declaration work?+
Sometimes immediately. Often, not. The book uses the metaphor of a locomotive versus a 10-second car — declaration usually builds momentum over time. The key is consistency and conviction. Don't be discouraged if you don't see immediate results. Sometimes God changes the situation, and sometimes He changes your heart toward the situation. Both are wins.
Is this a prosperity gospel book?+
No. Declare doesn't promise you'll get rich or that life will be easy if you say the right words. It's grounded in scripture and reality. It teaches biblical declaration as a tool in the believer's spiritual life — alongside prayer, worship, and obedience. Not as a shortcut to a perfect life.
Do I need to be a 'mature' Christian to read this?+
Not at all. The book is written to be accessible to new believers and challenging enough for seasoned Christians. If you have a Bible and a willingness to take God at His word, you have what you need.
What format is the book available in?+
The paperback edition is currently available on Amazon. It's designed to be a field manual you can mark up, dog-ear, and revisit — not a coffee table book to look at.
How long is the book?+
It's intentionally concise. Designed to be read, absorbed, and applied — not skimmed and shelved. Most readers can finish it in a few sittings, but its principles are meant to be lived out for a lifetime.
Stop spectating. Start declaring.
Pick up the paperback and learn how to call what God says into the physical realm — with conviction.
