Investigate the New Testament concept of “Pistis,” the Greek word often translated as faith or belief, in this fourth part of the “Key Words” series. Contrast the biblical understanding of faith with the common notion of mere intellectual assent, using the humorous analogy of believing in a chair versus actually sitting in it. Analyze the story of the Roman Centurion in Matthew 8, whom Jesus praised for having “great faith,” to understand faith as total confidence and reliance on Jesus’s authority and promises. Explore Hebrews 11’s “Hall of Faith” to see how genuine faith is always active and lived out. Discover that the foundation of our faith isn’t our own effort, but God’s unwavering faithfulness (His “hesed” love) toward us, even when we are faithless.
