Biblical Word Etymology
The Etymology of “Faith”
The biblical word “Faith” traces back to Ancient Hebrew (emunah), where it meant “Emunah - steadfast trust rooted in the faithfulness of God, not mere intellectual belief”. Across 5eras it evolved into the modern sense: “Faith reclaimed as relational fidelity - not blind belief but covenant loyalty”.
