So many times the word "Faith" is touted around, especially in debates concerning "blind faith" (and usually levelled at "believers"), but what is it really?
Heb 11:1 defines it as follows:
"Now faith is the substance of things hoped for, the evidence of things not seen." KJV
"Faith is the assured expectation of things hoped for, the evident demonstration of realities though not beheld." NWT
"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
Having been raised with the NWT, I always thought it a little vague, so I find the KJV a far better definition. It is distinct from hope (which appears to be the word so often transposed when folks object to "faith").
Hope is something not seen (Rom.8:24,25), but "Faith" appears to be the signature on the cheque. The evidence that the hope is not unfounded.
Given that according to scripture "Faith" is a fruit of the Holy Spirit, and the Holy Spirit is the "token" or "seal" by which we can have confidence in our adoption (Rom.8:15; Gal.4:5-7), it would follow that it is the very substance of our hope.
Better felt than telled, I guess...
Would that match your description of it?
