Regardless of whether the Bible is trustworthy or complete fiction, the consensus among Christian and non-Christian academics seems to be that the Bible's usage of the Greek word translated faith is intended to mean something akin to trust, not blind faith.1
The Oxford Companion to the Bible: “[It is a] kind of regard for or confidence in someone or something. … Abram's willingness to trust God… makes him the primary example of the biblical concept of faith.… a form of the Greek word pisteuein, 'to trust'…”[(Oxford, 1993), 222.]
International Standard Bible Encyclopedia: “The main sense of the word 'faith' in the NT is that of trust or reliance. …reliance on the thing or person in whom confidence is put,…” [2nd edition, Ed. by Bromiley (Eerdmans, 1982), 270-271.]
This corresponds to the Greek word translated faith: pistis (πίστις), which carries with it no notion of being evidentially unfounded.
Biblical heroes like Moses, the Apostles etc. had overwhelming evidence grounding their faith (having seen spectacular miracles).1 This is relevant because these same individuals are also known Biblically as great men of faith.
The Apostles etc. used evidence in their evangelism.1 (E.g. Jn 20:31 -- “but these have been written so that you may believe that Jesus is the Christ,” cf. 1 Cor 15:1-8). This is relevant because the apostles in doing so overtly undermine blind faith, and yet they would not do things which would sabatoge anyone's ability to have Biblical faith.
Biblical heroes encouraged people to “critically examine all things….” 1 This is relevant because this clearly undermines blind faith, and yet the Biblical heroes wouldn't encourage people to do things which would sabatoge their ability to have Biblical faith.
It says in Hebrews 11 -- “Now faith is the assurance of things hoped for, the conviction of things not seen. This is relevant because believing in things unseen more or less means believing things blindly (blind faith).
But wait, all things which are hoped for are unseen, “for who hopes for what he already sees?” (Rom 8:24). Still, countless beliefs are rational and well-evidenced while being unseen and hoped for. For example…
• …that your parachute will work when you jump out of the airplane.
• …that your spouse will be faithful after your wedding day.
Jn 20:29 -- “Jesus said to [Thomas], ‘Blessed are they who did not see [me], and yet believed.’” This is relevant because believing in things unseen more or less means believing things blindly (blind faith).
But wait, couldn't it simply be that…
…Jesus was stating a simple fact (they would be blessed), not critiquing Thomas.1
…Jesus was critiquing the stubborn/irrational nature of Thomas's disbelief.2
