What is meant by the terms 'substance' and 'evidence' in Hebrews 11:1?

The terms 'substance' and 'evidence' in Hebrews 11:1 are foundational to understanding faith in the Christian context. 'Substance' refers to the assured foundation upon which our hope rests, implying that faith gives us tangible assurance about our future promises. 'Evidence', on the other hand, speaks to the conviction or proof that supports our beliefs about the realities we cannot see, such as eternal life and God's presence. Together, these terms underscore the active and dynamic nature of faith, which assures us of God's faithful word and the reality of the unseen blessings we anticipate.
