I also read your entire commentary. And while it is nice and focuses on the meaning of faith for a believer, like most commentaries it leaves much else out and adds into it things it should not.
I do not put stock in commentaries, but the Word of God alone. Every verse is supported by every other verse. It does not need a commentary.
Here is the supporting verse for the EVIDENCE and SUBSTANCE and the duty to know the supposedly unknowable.
Prov 25:2 It is the glory of God to conceal a thing: but the honor of kings is to search out a matter.
He expects you to know and to have the faith that you CAN know.
Like I said: piece of work
God bless us all.
