NOW FAITH is the assurance (the confirmation, the title deed) of the things [we] hope for, being the proof of things [we] do not see and the conviction of their reality [faith perceiving as real fact what is not revealed to the senses].
Amplified Bible
Now faith is being sure of what we hope for and certain of what we do not see.
New International Version
Now faith is the substance of things hoped for, the evidence of things not seen.
King James Version
The fundamental fact of existence is that this trust in God, this faith, is the firm foundation under everything that makes life worth living. It’s our handle on what we can’t see.
The Message
Faith is the confidence that what we hope for will actually happen; it gives us assurance about things we cannot see.
New Living Bible
