Hebrew 11:1-2, 8-19
The author of the Letter to the Hebrews gives us a profound definition of faith: “Now faith is the foundation of things hoped for, the evidence of things not seen” (Hebrews 11:1-2). But what does this truly mean?

Faith as a Firm Foundation
The Greek word used for “foundation” is ὑπόστασις (hupostasis), which literally means “that which stands underneath.” This tells us that faith is not a fleeting emotion or a momentary burst of belief. It is not something can instantly be produced through loud music or strong screams. Instead, it is a steady, unshakable confidence in God’s promises. Faith anchors us, giving substance to what we hope for even when we cannot yet see it.
Faith as Convincing Evidence
The author also describes faith as ἔλεγχος (elengkos), a term often used in legal contexts to refer to irrefutable proof. In a courtroom, verified evidence determines guilt or innocence. Similarly, faith serves as undeniable confirmation of spiritual realities we cannot perceive with our physical senses, our eyes, our ears, and our mouth. Though unseen, these realities are just as real because faith testifies to their truth.
Where Does Such Faith Come From?
But how can faith be so strong? How can it serve as both foundation and evidence? The answer lies in its source: faith does not originate from within us but from God’s faithfulness. The promises we hope for are not human wishes but divine guarantees. Since God is trustworthy, our faith rests on His unchanging commitment to fulfil His promises
Then, how do we know God is truly faithful? History proves it. The Old Testament is filled with stories of God keeping His word, and Hebrews highlights Abraham as a key example. At seventy-five, Abraham obeyed God’s call to leave his comfortable homeland for an unknown future and uncharted land. Despite his old age and Sarah’s barrenness, he believed God’s promise of descendants as numerous as the stars. Even when tested with the unthinkable, sacrificing his son Isaac, Abraham trusted God’s faithfulness that everything would turn just right. He died without seeing the full fulfilment, yet God’s promises came to pass.
The Ultimate Fulfilment in Christ
Hebrews shows us that God’s faithfulness, demonstrated through generations, culminates in Jesus Christ. He is the final and fullest expression of God’s promises. He was born like us humans, suffered and died for us, and resurrected. Our faith, therefore, is not only built on emotions or human reasoning but on historical acts of God, proven in the lives of believers before us and sealed in Christ. Faith is more than simple belief. It is trust in the One who has never failed. And because God is faithful, we can stand firm, even when the path ahead is unseen.

Reflection Questions
- How do we understand faith? Is it merely an emotional feeling, a product of logic, or a personal encounter with God?
- Have we faced moments of doubt or a crisis of faith? How did we overcome them?
- How does recognizing God’s faithfulness in Scripture strengthen our trust in Him today?
