Delve into the rich meaning of “Zoe,” the Greek word for life, in this fifth part of the “Key Words” series. Contrast Zoe (spiritual, eternal life) with “Bios” (biological life, lifespan), understanding Paul’s concept in Ephesians 2 that one can be biologically alive yet spiritually “dead in trespasses and sins.” Explore how the New Testament presents Christ not just as the giver of life, but as life itself (“Christ who is our life,” Colossians 3:4). Discover the profound truth that eternal life (Zoe Aionios) isn’t just a future promise but a present reality—a quality of life experienced now through knowing God and His love (John 17:3). Understand how salvation makes us truly human, restoring the abundant life God intended.
