“What use is it for a man to say he has faith when he does nothing to show it?” ask James. (James 2: 14) “With faith; if it does not lead to action, it is in itself a lifeless thing.”
The author of Hebrews asks, “And what is faith?” And offers this answer: “Faith gives substance to our hopes, and makes us certain of realities we do not see.” (Hebrews 11: 1)
Abel offers a better sacrifice than Cain by believing God is good. “Without faith it is impossible to please [God]; for anyone who comes to God must believe that He exists and that He rewards those who search for Him.” (Hebrews 11: 6)
Jesus says that faith as tiny as a mustard-seed is able to “give substance to our hopes.” Our faith is not in our good deeds, but in Christ, “for it is in Christ that the complete being of the Godhead dwells embodied, and in Him [we] are brought to completion.” (Colossians 2: 9)
Our faith is not lifeless, but alive. Though we do not see the realities of which we are certain, our faith does indeed “give substance to our hopes.” And this living faith allows us to act.
