Blind faith: trust in the law of Moses (Jn 1:17; 5:45)
Seeing faith: some "better" thing God hath provided for "us" (Heb 11: conclusion)

Seeing faith is based on what's evident from the evidence, not on theories or doctrines of men.

Result of blind faith: these all died and received not the promise (Heb 11)

Result of seeing faith: awareness and understanding.

With all thy getting, get understanding (Prov 4:7).

Whatsoever is not of faith is sin: Rom 14:23b
The law is not of faith: Gal 3:12a
"You" do the allegorical reasoning.
And remember the end of the commandment:
Love(God) one another, as I have loved "you".

I don't see the harm in it(law)... famous last words.
The POINT of the God shew is to SEE the harm in it.
Selah.
