1. Hebrews 11:1
"Now faith is confidence in what we hope for and assurance about what we do not see."
This classic definition introduces Hebrews 11, "The Faith Hall of Fame." The Greek word "hypostasis" (confidence/substance) means underlying reality or foundation - faith gives substance to our hopes. "Elegchos" (assurance/evidence) is a legal term meaning proof that convinces. Faith isn't wishful thinking but conviction based on God's promises. It bridges the gap between present reality and future hope, making unseen spiritual realities as real as visible things (Calvin's Commentary).
