Faith is everywhere—quoted in churches, worn on T-shirts, tattooed on skin—but do we really understand it?
In a culture saturated with spiritual slogans and feel-good mantras, the word faith gets tossed around so frequently that its depth often gets lost. You’ve likely heard it in moments of crisis—“Just have faith”—or seen it stitched into home décor or whispered in hospital corridors. Yet, when we stop and ask, “What is Faith?”, the answers can range from poetic to puzzling.
As a lifelong student of Scripture and a teacher of biblical theology, I’ve spent years walking people through the layers of this question. Faith isn’t just a religious buzzword—it’s the bedrock of Christian belief, the bridge between human weakness and divine strength. It is the thread that runs through every story of redemption in the Bible, the starting point of spiritual growth, and the heartbeat of Christian living.
But faith is more than belief in something unseen. It’s more than crossing your fingers and hoping for the best. According to the Bible, faith is a dynamic, living trust in God that transforms how we think, act, and live. It’s about assurance in God’s promises and conviction about spiritual truths—even when we don’t have all the answers.
Key Takeaway
In publication, we’re going to unpack the question “What is Faith?” in a way that’s both deeply rooted in Scripture and powerfully relevant to your everyday life. Together, we’ll explore:
- How faith is defined in the Bible
- How it plays a central role in salvation
- How it fuels our trust in God during life’s hardest moments, and
- How it’s meant to be lived out—not just believed in.
So whether you’re brand-new to Christian faith or a seasoned believer wanting to go deeper, this journey through the meaning and power of faith is for you.
What is Faith? — Question For Everyone
Ask ten people “What is Faith?” and you’ll likely get ten different answers. Some will say it’s blind belief, others call it hope, and still others confuse it with mere optimism. But Scripture gives us a definition that is both poetic and profoundly practical:
“Now faith is the assurance of things hoped for, the conviction of things not seen.”
— Hebrews 11:1
This verse, often quoted but rarely understood, offers two anchoring truths about faith: assurance and conviction. These aren’t vague feelings. They speak of confident trust in God’s promises (assurance), and a deep-rooted belief in spiritual realities we cannot yet see (conviction).
Let’s break that down.
Faith Is Trust in God—Not Just Belief in Ideas
Faith goes beyond believing that God exists. Even demons believe in God (James 2:19), but they don’t trust Him. Real faith, biblical faith, is an active, relational trust. It’s like leaning your full weight on a chair—not just believing it can hold you, but actually sitting down.
In the context of Christianity, faith means trusting that God is who He says He is, and that He’ll do what He’s promised—even when life’s circumstances scream otherwise. It’s trusting God’s heart when you can’t trace His hand.
Faith Includes Intellectual Belief—but It Doesn’t Stop There
Yes, faith has a rational element. You need to know what you believe. This includes understanding who Jesus is, what He did, and what Scripture teaches about salvation, grace, and spiritual growth. But intellectual belief alone isn’t enough.
Biblical faith always moves from the head to the heart—and then to the hands. It engages your mind, transforms your inner world, and results in outward action. As James 2:17 reminds us, “faith by itself, if it does not have works, is dead.”
Faith is Rooted in Relationship, Not Religion
Another common misconception is that faith is about following rules or checking off spiritual boxes. But the Bible paints a different picture. Faith is deeply relational. Abraham’s faith wasn’t about rituals—it was about trusting God when he was told to leave everything familiar and follow a promise (Genesis 12:1-4, Romans 4:20-21).
True faith means walking closely with God, growing in dependence on Him, and living in step with His Spirit. It’s not about perfection; it’s about posture—a posture of trust in God that reorients every part of your life.
Faith and Salvation: The Gateway to Grace
When we ask, What is Faith?, we can’t ignore the central role it plays in the greatest spiritual question of all: How are we saved?
The Bible answers that without hesitation:
“For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.”
— Ephesians 2:8–9
This passage captures the heart of the Christian faith. Salvation isn’t earned. It’s not a reward for good behavior or spiritual hustle. It is grace—pure, undeserved favor—received through faith.
Grace Is the Gift. Faith Is the Door.
Let’s not confuse the means with the source. Grace comes from God. Faith is how we receive it. Faith is the open hand that takes hold of God’s rescue plan. It doesn’t add anything to grace; it simply accepts it.
So when someone asks, “What is Faith?”, part of the answer is this: Faith is the God-ordained way we enter into salvation and begin a transformed life. It’s not just believing God exists. It’s trusting that Jesus’ death and resurrection are enough to make you right with God.
Faith and Works: Not a Competition, but a Sequence
Another big question surrounding faith and salvation is this: If we’re saved by faith, do works even matter?
James 2:26 clears that up:
“For as the body apart from the spirit is dead, so also faith apart from works is dead.”
Works don’t save us. But they do flow naturally out of a living faith. It’s the difference between a seed and a tree. The seed of faith planted in salvation should produce fruit—actions, attitudes, and a way of life that reflects Christ.
This is where belief turns into Christian living. Where trusting in God changes how you spend, speak, serve, and suffer. When faith is real, it shows.
Saving Faith Is Personal and Transformational
There’s a reason John 3:16 is the most quoted verse in all of Scripture:
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.”
What is Faith? It’s the personal response to God’s love and the doorway to eternal life. It’s not inherited. It’s not automatic. And it’s not academic. It’s personal, relational, and eternal.
If grace is the wind, faith is the sail—opening your life to the movement of God and setting you on a course toward eternal hope.
Living by Faith: Action, Obedience, and Trust in God
Once we understand the answer to What is Faith? from a biblical lens, the next question is inevitable: What does faith look like in everyday life?
The short answer? Faith moves.
Faith is not a dormant belief or a spiritual accessory you wear to church on Sunday. It is a way of living. It shapes your decisions, your reactions, your relationships, and your resilience. Faith isn’t just about eternity—it’s about how you navigate Tuesday afternoon traffic, raise your kids, fight temptation, and face a doctor’s diagnosis.
“So also faith by itself, if it does not have works, is dead.”
— James 2:17
James isn’t contradicting Paul’s message of salvation by grace—he’s confirming it. True, saving faith will always bear fruit. It trusts in God’s character and responds with obedience, even when the path ahead is unclear.
Faith Is Trust That Walks
Paul writes in 2 Corinthians 5:7:
“For we walk by faith, not by sight.”
This isn’t just poetic language—it’s the Christian life in motion. Living by faith means stepping forward before all the answers are visible. It means choosing God’s promises over what culture, fear, or your feelings might say.
So when we ask, What is Faith?, the answer includes this:
Faith is trusting in God enough to obey Him, even when it costs you something.
Faith in Uncertain Times
Faith shows its true strength when life shakes. When the job is lost, the diagnosis is grim, the relationship is broken—faith holds steady. Why? Because its anchor is not in circumstances but in a sovereign God who does not change.
Proverbs 3:5–6 says it beautifully:
“Trust in the Lord with all your heart, and do not lean on your own understanding.
In all your ways acknowledge him, and he will make straight your paths.”
Christian living isn’t always neat or painless. But when you’re walking by faith, you are not walking alone. You are walking in trust, and God walks with you.
Living Faith: Real People, Real Faith
Throughout Scripture, we see how faith takes shape in real lives:
- Abraham trusted God enough to leave everything familiar and believe in an unseen promise.
- Noah built a massive ark when the sky was clear and neighbors laughed.
- The disciples left their livelihoods to follow a Rabbi who promised a kingdom they couldn’t yet see.
Faith doesn’t always make sense in the moment. But it always makes miracles possible.
Faith in the Bible: Verses That Illuminate and Inspire
The Bible doesn’t just define faith—it narrates it, commands it, and celebrates it. When someone asks, “What is Faith?”, the Scriptures themselves offer the most vivid answers—not as theories, but as living truth.
Here are key Bible verses that not only define faith, but also show its power, purpose, and promise:
1. Hebrews 11:1 – The Classic Definition
“Now faith is the assurance of things hoped for, the conviction of things not seen.”
This single verse is the bedrock of the biblical faith definition. Notice the dual dynamic:
- Assurance (elpis)—a confident expectation grounded in God’s trustworthiness.
- Conviction (elegchos)—a firm belief in unseen realities.
So when we ask What is Faith?, we find this: Faith is spiritual certainty in a physical world.
2. Ephesians 2:8–9 – Faith and Salvation
“For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.”
Faith is the means, not the source, of salvation. Grace is the gift; faith is how we receive it. These verses strip away performance-based religion and remind us that salvation is not earned—it’s received by faith.
3. James 2:17 – Faith That Works
“So also faith by itself, if it does not have works, is dead.”
Far from contradicting Paul, James brings out the other side of the same coin: Living faith is active faith. It’s faith that builds bridges, forgives enemies, serves the poor, and stays loyal in trials. If someone asks, “What is Faith?”, the answer must include this truth:
Faith transforms behavior because it trusts God more than self.
4. Romans 10:17 – How Faith Grows
“So faith comes from hearing, and hearing through the word of Christ.”
This verse is crucial for anyone pursuing spiritual growth. Faith is not self-generated. It is sparked and strengthened by hearing God’s Word. In other words, if you want your faith to grow—feed it truth.
5. Proverbs 3:5–6 – Daily Trust in God
“Trust in the Lord with all your heart, and do not lean on your own understanding.
In all your ways acknowledge him, and he will make straight your paths.”
This is one of the most beloved Bible verses about faith—and for good reason. It’s a call to full-hearted trust in God, not partial or conditional. When you ask, “What is Faith?”, here’s one answer:
Faith is trusting God when logic says otherwise.
6. 2 Corinthians 5:7 – The Daily Walk
“For we walk by faith, not by sight.”
Faith is not a leap—it’s a walk. It’s daily decisions in the direction of trust, not visible certainty. You may not see the end of the road, but you trust the One who paved it.
These verses—and many more—paint a full picture of what biblical faith really means. Faith is not a feeling; it’s a conviction. It’s not vague optimism; it’s anchored assurance. It’s not a fallback when life gets hard; it’s the very fuel of the Christian life.
Everyday Faith — How to Live It Today
When people ask, “What is Faith?”, they’re rarely asking for a theological lecture. Most often, they want to know:
“What does faith look like on Monday morning? When I’m facing real problems, how does faith help me?”
The good news is: faith is not just a belief system—it’s a life system.
1. Faith Means Trusting God When Life Doesn’t Make Sense
It’s easy to say we have faith when everything is going right. But what about:
- A job loss?
- A diagnosis?
- A silent heaven?
This is where faith becomes real. Proverbs 3:5-6 isn’t poetic fluff—it’s a daily command:
“Trust in the Lord with all your heart… and He will make your paths straight.”
What is Faith? It’s trusting God’s character when you can’t trace His hand.
2. Faith Anchors Us in God’s Promises, Not Our Performance
In a culture obsessed with achievement, faith says:
“You are not defined by what you do, but by who God is.”
This doesn’t lead to laziness—it leads to peace. Because when you know God is faithful, you don’t have to be perfect. You can rest in His grace. That’s spiritual growth.
As Ephesians 2:8-9 reminds us, faith connects us to grace—not just once at salvation, but every day afterward.
3. Faith Fuels Obedience, Even When It’s Hard
When Abraham left his home with no map (Genesis 12), or when Peter stepped out onto the water (Matthew 14), they didn’t act on certainty—they acted on faith.
What is faith? It’s obedience before the outcome.
Today, that might look like:
- Forgiving someone who doesn’t deserve it
- Staying honest in your taxes
- Giving generously even when it feels tight
This is what James meant when he said, “faith without works is dead.” Faith does.
4. Faith Prays with Confidence
Faith doesn’t just wait—it asks boldly. Jesus said in Mark 11:24:
“Whatever you ask in prayer, believe that you have received it, and it will be yours.”
That doesn’t mean God is a vending machine—but it does mean faith is confident hope in God’s power and timing.
When you live by faith, prayer becomes your first move, not your last resort.
5. Faith is a Lens for Life
Walking by faith means seeing the world differently:
- Where others see fear, you see opportunity.
- Where others see delay, you see God’s timing.
- Where others see weakness, you remember that God’s strength is made perfect in it.
That’s why 2 Corinthians 5:7 says:
“We walk by faith, not by sight.”
Faith changes your vision, not just your vocabulary.
Everyday faith is more than just belief—it’s a posture. It’s how we carry ourselves when we trust that God is real, His Word is true, and His promises will come to pass.
So, what is faith? It’s the quiet confidence that no matter what happens, God is who He says He is, and He will do what He says He’ll do.
Real People, Real Faith Examples That Speak
Understanding the meaning of What is Faith? becomes more vivid when we see it lived out. The Bible is filled with stories of people who didn’t just talk about faith—they walked it, breathed it, and staked everything on it. Their lives offer a living definition of what belief, trust in God, and conviction really look like.
1. Abraham — Faith That Waits and Obeys
Abraham is often called the father of faith, and for good reason. God told him he would be the father of many nations—before he had a child and after he was well past childbearing age.
“Abraham believed God, and it was credited to him as righteousness.” (Genesis 15:6)
He obeyed God’s call to leave his homeland without knowing the destination (Hebrews 11:8). Later, he was even willing to sacrifice Isaac, the very child of promise, trusting that God could raise him from the dead (Hebrews 11:17–19).
Abraham teaches us that faith isn’t passive waiting—it’s active trust in the unseen promises of God.
2. The Woman with the Issue of Blood — Faith That Reaches Out
In Mark 5:25–34, a woman who had been bleeding for 12 years believed that if she could just touch Jesus’ robe, she would be healed.
She didn’t have a theological degree or a seat of honor in the synagogue—but she had belief. And Jesus honored her courage and faith:
“Daughter, your faith has healed you. Go in peace.” (Mark 5:34)
Her story shows us that faith in God sometimes looks like desperate hope wrapped in action—and that’s enough for Jesus.
3. The Disciples — Faith That Follows
When Jesus called His first disciples, He simply said, “Follow me.” And they did. They left careers, families, and everything familiar to walk with a man who had no earthly credentials. (Matthew 4:18–22)
That wasn’t blind faith. It was conviction rooted in the trust that Jesus was who He claimed to be.
Even when they failed—as Peter did when he sank on the water—they learned that faith also includes getting back up and growing spiritually from the stumble (Matthew 14:30–31).
4. Modern Believers — Faith in the Everyday
Faith isn’t just a Bible-era phenomenon. Today, countless Christians around the world are living by faith:
- Parents trusting God while raising children in a chaotic world
- Professionals choosing integrity over profit
- Students believing God has a plan beyond the pressure of grades
- People fighting illness while clinging to hope in Christ
Faith means living with assurance even when the outcome is unknown—and trusting that God is present in every moment, big or small.
Each of these examples reminds us that faith is never abstract. It’s deeply personal, often costly, and always powerful. It shows up in crisis, in calling, in quiet prayers, and bold moves. And it answers the question “What is Faith?” with real lives that speak louder than definitions.
Conclusion: Walking by Faith, Not by Sight
So, what is faith?
After walking through its biblical roots, theological weight, and real-life application, we can now say: faith is more than belief—it’s the living, breathing confidence in who God is and what He promises, even when we can’t see the full picture.
Faith is trust in God when the path is unclear.
It’s conviction in what’s eternal while living in a temporary world.
It’s assurance that even in suffering, confusion, or doubt, God is still faithful.
“For we walk by faith, not by sight.” (2 Corinthians 5:7)
This walk isn’t always easy. But it’s the path that leads to spiritual growth, peace that passes understanding, and a life anchored in grace.

Frequently Asked Questions: What Is Faith?
What is faith according to the Bible?
The Bible defines faith in Hebrews 11:1 as “the assurance of things hoped for, the conviction of things not seen.” In essence, faith is trusting in God’s promises, even when they’re not yet visible or fully understood. It combines belief, trust in God, and obedience to His Word.
Is faith just believing in God?
Not exactly. While belief in God is part of faith, biblical faith goes deeper—it involves personal trust, surrender, and action. James 2:19 says even demons believe in God—but they don’t trust or obey Him. True Christian faith results in a transformed life and spiritual growth.
How do I grow my faith?
Faith grows by hearing God’s Word (Romans 10:17), spending time in prayer, and walking in obedience—even when it’s hard. Surrounding yourself with other believers and reflecting on God’s faithfulness also strengthens trust and deepens your faith meaning over time.
Can I have faith and still doubt?
Yes. Many biblical figures experienced doubt—Abraham, Thomas, even John the Baptist. But doubt doesn’t disqualify faith. Faith is choosing to trust God in spite of doubt. Bring your questions to Him. He welcomes honest hearts (Mark 9:24).
What’s the difference between faith and works?
Faith is the root; works are the fruit. We are saved by grace through faith (Ephesians 2:8-9), not by works. However, genuine faith produces good works as evidence of a changed heart (James 2:17). They work together, not in opposition.
Is faith a gift from God?
Yes. Ephesians 2:8 calls faith “the gift of God.” While we respond to God with belief and trust, the ability to believe and follow Him originates in His grace. This gift invites us into a relationship with Him, not just a belief system.
What does “walk by faith, not by sight” mean?
It means we live in dependence on God’s Word and promises, not just what we can see, feel, or control. Even when circumstances look impossible, faith holds onto what God says is true (2 Corinthians 5:7).
How does faith affect everyday life?
Faith influences everything—from how you make decisions to how you handle suffering, finances, relationships, and your purpose. It’s a lens through which we see the world: one that trusts in God’s guidance, timing, and goodness in every moment.
