What does the Bible say about faith that does not save?

In John 11:45, we see that many believed in Jesus after witnessing the resurrection of Lazarus. However, this belief was not saving faith because it was based on what they saw rather than on spiritual conviction. True saving faith, as articulated in Hebrews 11:1, is the substance of things hoped for and the evidence of things not seen. Therefore, while many have a form of faith, only that which looks beyond physical evidence—trusting fully in Christ without reliance on sight or personal experience—is saving faith.
