Many people today confuse faith with a kind of mental force or human effort. But biblical faith is not confidence in faith itself — that’s just another form of humanism. Real faith is confidence in a Person: the God who cannot lie and who always keeps His promises.
Sarah’s Story: When Facts Bow to Truth
Take Sarah as an example. The fact was that she was barren. But the truth was that God promised she would bear a son.
At first, she couldn’t see it. She even laughed at the promise (Gen. 18:12). Yet eventually, she believed the One who had promised, and in time, the facts became aligned with the truth.
Faith doesn’t ignore reality. It acknowledges the facts — but it clings to God’s truth until facts are forced to bow.
Abraham’s Assurance
Paul describes Abraham’s confidence this way:
“He was fully convinced that God was able to do what He had promised.”— Romans 4:21
Why? Because Abraham knew that God could create whatever was needed to fulfill His word, even calling into being things that did not exist (Rom. 4:17).
Paul J. Achtemeier comments:
“Hope that such a God will fulfill his promises can therefore never prove unfounded, even when all appearances go against it.”
(Romans, Interpretation Commentary, p. 82)
This is the essence of faith: not wishful thinking, but trust in the God who can make something out of nothing.
Faith Flows Out of Relationship
Faith flows from knowing the character of the One who makes the promise.
Hebrews 11 shows this in Abraham’s willingness to sacrifice Isaac:
- God had promised Abraham countless descendants through Isaac.
- Yet Abraham was willing to lay Isaac on the altar.
- Why? Because he reasoned that God could raise Isaac from the dead — even though resurrection was unheard of (Heb. 11:17–19).
Abraham’s faith wasn’t in his own ability to figure things out. His faith was in the faithfulness of God.
What This Means for Us
- Faith is not self-confidence; it’s God-confidence.
- Faith doesn’t deny facts; it trusts God until facts align with truth.
- Faith is rooted in relationship — the more we know His character, the more assured we become that He will perform what He has promised.
As Paul puts it:
“Faith comes by hearing, and hearing by the word of Christ” (Rom. 10:17).
Faith grows as we walk with the One who speaks, promises, and never fails.
Conclusion
Biblical faith is not about mustering inner strength. It is about being fully persuaded, like Abraham and Sarah, that God is able to do what He promised.
Faith is trust in a Person — and that Person is faithful.
