What does Hebrews say about the nature of faith?

In Hebrews 11:1, faith is described as the substance and confidence of things hoped for and the evidence of things not seen. This definition underscores faith's role as a conviction that transcends physical evidence, firmly rooted in trust in God's character and promises. The chapter goes on to present various historical figures, showing that their salvation was not based on the magnitude of their faith but on faith's object—God Himself. Every example demonstrates that believing in God's promises was the distinguishing factor for their righteousness. This assurance emerges clearly through the acknowledgment of God's unchanging nature and the corresponding hope we possess in Christ, who fulfills all God's promises.
