What is Faith?

What is faith? The Bible in Hebrews 11:1 gave us the definition of faith.

And faith (πίστις) is of things hoped for (ἐλπιζομένων) a confidence (ὑπόστασις), of matters (πραγμάτων) not seen (οὐ βλεπομένων) a conviction (ἔλεγχος), (Hebrews 11:1 YLT)

Faith is the reality of what we hope for, the proof of what we don't see. (Hebrews 11:1 CEB)

Faith makes us sure of what we hope for and gives us proof of what we cannot see. (Hebrews 11:1 CEV)

Now faith is being sure of what we hope for, being convinced of what we do not see. (Hebrews 11:1 NET)

Now faith is the assurance (title deed, confirmation) of things hoped for (divinely guaranteed), and the evidence of things not seen [the conviction of their reality - faith comprehends as fact what cannot be experienced by the physical senses]. (Hebrews 11:1 Amplified Bible)

Now faith is confidence in what we hope for and assurance about what we do not see. (Hebrews 11:1 NIV)

Faith shows the reality of what we hope for; it is the evidence of things we cannot see. (Hebrews 11:1 NLT)

Now faith is the assurance of things hoped for, the conviction of things not seen. (Hebrews 11:1 ESV)

Now faith is the assurance of what we hope for and the certainty of what we do not see. (Hebrews 11:1 BSB)

Now faith is the reality of what is hoped for, the proof of what is not seen. (Hebrews 11:1 CSB)

Now faith is the substance of things hoped for, the evidence of things not seen. (Hebrews 11:1 KJV, MEV)
