Hebrews 11:1
What Is Faith? The Bible's Definitive Answer
Introduction: The Faith Chapter's Opening Definition
Hebrews 11:1 contains perhaps the most famous and comprehensive definition of faith in all of Scripture. This single verse has been memorized by countless believers, quoted in sermons throughout church history, and studied by theologians seeking to understand the nature of genuine biblical faith. Often called the "faith chapter," Hebrews 11 begins with this foundational definition before proceeding to illustrate faith through the lives of Old Testament heroes.
This detailed exposition examines Hebrews 11:1 word by word, exploring the rich Greek terminology, theological implications, and practical applications of this profound definition. Understanding what faith is—and what it is not—is essential for every Christian seeking to grow in their relationship with God.
Context of Hebrews 11
Hebrews 11 does not stand alone. Chapter 10 concludes with the famous declaration "the just shall live by faith" (Hebrews 10:38), quoting Habakkuk 2:4. Chapter 11 then defines and illustrates this faith. Chapter 12 calls believers to run the race with endurance, looking to Jesus, "the author and finisher of faith." Hebrews 11:1 is the bridge between the call to live by faith and the examples of those who did.

Word-by-Word Exposition
📖 "Now Faith Is..." (Pistis)
The Greek word for faith (pistis) encompasses trust, confidence, conviction, and faithfulness. In the New Testament, faith is not merely intellectual assent but active trust and commitment. Biblical faith involves the whole person—mind, heart, and will.
Important: The author does not say "faith was" but "faith is"—this is a timeless definition, applicable to all believers in all ages. The definition is also comprehensive, covering both future realities ("things hoped for") and invisible realities ("things not seen").
💎 "Substance/Assurance" (Hypostasis)
The Greek word hypostasis is rich and complex. It appears only five times in the New Testament. Its meanings include:
- Foundation or basis: That which underlies something
- Confident assurance: Certainty, firm conviction
- Reality or substance: Actual existence, not mere imagination
- Title deed: Legal document guaranteeing ownership
Theological Significance: Faith is not wishful thinking or blind leap. It is hypostasis—solid, substantial, real. Faith provides present certainty about future promises. Like a title deed guarantees future possession, faith guarantees the reality of what God has promised. What we hope for is not uncertain; faith makes it present reality to the believer.
🎯 "Things Hoped For" (Elpizomenon)
Christian hope is not uncertainty ("I hope so") but confident expectation ("I know so"). Biblical hope is eschatological—oriented toward future fulfillment of God's promises: resurrection, eternal life, Christ's return, the new heaven and earth.
Key Point: Faith does not create hope; faith substantiates hope. The objects of hope are real because God promised them. Faith makes these future realities present possessions. We hope for what we do not yet have, but faith assures us we will receive it (Romans 8:24-25).
🔍 "Evidence/Conviction" (Elegchos)
The Greek word elegchos means proof, conviction, or evidence that convinces. It refers to evidence so compelling it produces inner conviction. This word is related to elenchō, meaning to convict or convince.
Theological Significance: Faith provides inner conviction about invisible realities. Just as physical senses provide evidence of physical reality, faith provides evidence of spiritual reality. Faith is not contrary to evidence—it is evidence of a different order, spiritual evidence perceived by spiritual senses.
👁️ "Things Not Seen" (Blepomenon)
This phrase encompasses all spiritual realities not perceivable by physical senses: God Himself, angels, the soul, heaven, hell, spiritual truths. Faith perceives what eyes cannot see.
Important Distinction: "Not seen" does not mean "not real." God is not seen but is most real. Heaven is not seen but is more permanent than earth. Faith perceives ultimate reality, not merely apparent reality. As Paul wrote, "We look not at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal" (2 Corinthians 4:18).
Complete Definition of Biblical Faith
Based on Hebrews 11:1, biblical faith can be defined as:
- Firm conviction produced by God in the believer's heart
- Present assurance of future promises God has made
- Inner certainty about spiritual realities not perceivable by physical senses
- Active trust that rests on God's character and Word
- Supernatural perception that sees beyond visible circumstances to invisible realities
Faith is NOT: Blind leap, wishful thinking, positive confession, self-generated optimism, or intellectual assent without trust.
Two Dimensions of Faith
⏰ Faith and Time: Present Assurance of Future Reality
Hebrews 11:1 reveals faith's relationship to time. Faith brings future promises into present experience. What God has promised for the future, faith appropriates now. This is not making the future happen but recognizing that God's promises are so certain they can be treated as present reality.
Example: Abraham believed God's promise of descendants and land. Though he died without seeing complete fulfillment, faith made the promise present reality to him (Hebrews 11:13-16).
🌐 Faith and Reality: Conviction About Invisible Truth
Hebrews 11:1 also reveals faith's relationship to reality. The physical world is not the only—or even the ultimate—reality. Spiritual realities (God, heaven, eternal life) are more real than physical realities, though invisible to physical eyes. Faith perceives this ultimate reality.
Example: Moses "endured as seeing Him who is invisible" (Hebrews 11:27). Moses perceived God's reality more clearly than Egypt's visible splendor, leading him to reject Egypt for God's purposes.
Faith in the Rest of Hebrews 11
The definition of 11:1 is illustrated throughout the chapter. Each example demonstrates faith as substance of things hoped for and evidence of things not seen:
📚 Examples from Hebrews 11
- Abel (v. 4): Offered better sacrifice by faith—assured of unseen approval
- Enoch (v. 5-6): Walked with God by faith—convinced of unseen reward
- Noah (v. 7): Built ark by faith—assured of unseen flood
- Abraham (v. 8-19): Obeyed and offered by faith—convinced of unseen promises
- Moses (v. 23-29): Chose God by faith—saw the invisible God
- Rahab (v. 31): Welcomed spies by faith—assured of unseen deliverance
Each example shows faith providing present certainty about future or invisible realities—exactly what 11:1 defines.
Practical Applications
Living Out Hebrews 11:1
- Trust God's Promises: Identify specific promises in Scripture. Claim them by faith, knowing they are as certain as if already fulfilled. God's Word is more reliable than visible circumstances.
- Perceive Spiritual Reality: When circumstances contradict God's truth, choose faith over sight. What God says is more real than what you see. Train yourself to perceive spiritual reality through faith.
- Act on Faith: Biblical faith produces action (James 2:17). If you believe God's promises are real, live accordingly. Make decisions based on eternal reality, not temporary circumstances.
- Endure Through Testing: Faith's assurance sustains believers through trials. When you cannot see God working, faith assures you He is. When you cannot understand, faith trusts His character.
- Grow in Faith: Faith grows through hearing God's Word (Romans 10:17). Read Scripture regularly. Meditate on God's promises. Remember past faithfulness. Faith strengthens through exercise (Hebrews 5:14).
- Look to Jesus: Hebrews 12:2 calls believers to look to Jesus, the author and finisher of faith. He is both the source of faith and its perfect example. Union with Christ strengthens faith.
Faith and Reason
Hebrews 11:1 does not teach faith against reason but faith beyond reason. Faith is not irrational but trans-rational—perceiving realities reason cannot reach. Faith has its own evidence (the Word of God, the Spirit's witness, transformed lives) just as reason has its evidence (observation, logic, experience). Both are valid ways of knowing; faith knows spiritual realities reason cannot access.
"Faith is not belief without evidence, but trust in the One who has all evidence. Faith is not closing our eyes but opening them to realities we cannot see with physical sight."— Adapted from various Christian teachers
Conclusion: The Foundation of Christian Life
Hebrews 11:1 provides the foundation for understanding biblical faith. Faith is not vague hope but solid assurance. It is not blind leap but confident conviction. It is not self-generated but God-given. It is not optional but essential—"without faith it is impossible to please God" (Hebrews 11:6).
This definition challenges believers to examine their faith. Is it substantial—providing real assurance? Is it convicting—producing inner certainty? Is it oriented toward things hoped for and things not seen? Or has faith become merely intellectual assent or emotional experience?
May we cultivate the faith Hebrews 11:1 describes—faith that perceives invisible reality, appropriates future promises, and pleases the God who rewards those who diligently seek Him. Like the heroes of Hebrews 11, may we live by faith, die in faith, and receive the end of our faith—the salvation of our souls (1 Peter 1:9).
