Hebrews 11:1

ἔστιν δὲ πίστις ἐλπιζομένων ὑπόστασις, πραγμάτων ἔλεγχος οὐ βλεπομένων.

estin de pistis elpizomenōn ypostasis, pragmatōn elegchos oy blepomenōn.

King James Version (KJV)

Now faith is the substance of things hoped for, the evidence of things not seen.

Modern English

Now faith is confidence in what we hope for and assurance about what we do not see.
