Now faith is
Hebrews 11:1
1Now faith is the assurance of things hoped for, the conviction of things not seen.
What's happening here
The letter to the Hebrews is written to Christians under pressure — family disownment, the loss of property, the slow grind of being the wrong kind of people in a hostile city. Chapter 11 is the famous roll call of faith: Abraham, Sarah, Moses, Rahab, and the unnamed ones who were sawn in two. But the chapter opens with a definition, and the single Greek noun the author picks for what faith IS has made translators sweat for two thousand years.
The word that matters
Greek · what stands under — foundation, substance, ground
Hypostasis is built from hypo (under) and stasis (standing). It is the word philosophy used for what a thing is underneath all appearance — its substance, what it stands on. The KJV translated it as "substance." Modern translations try "assurance" or "confidence." Both are defensible. But the image the author reaches for is not a feeling at all. Faith is the ground under your feet when the future has not happened yet.
Where else this shows up
Hebrews 11:3
Two verses on: "what is seen was not made out of things that are visible." Hypostasis as the invisible ground of the visible.
2 Corinthians 4:18
"The things that are seen are transient, but the things that are unseen are eternal." Same theology, different vocabulary.
Hebrews 1:3
The same noun: the Son is the "exact imprint of his hypostasis" — the underneath-ness of God made visible.
