From living by faith (Habakkuk 2:4) to the circumcision of the heart (Deuteronomy 10:16; 30:6).

A couple of thoughts about your comments.

Concerning the Habakkuk scripture, Paul quotes it three times in the New Testament to describe justification/salvation by faith.
Romans 1:17 (the Just)
Gal 3:11 (shall live)
Heb 10:38 (by faith)

I have a couple notes in my Bible at Hab 2:4 that I am not sure of their source.
The first is "Grandfather of the Reformation" I think I heard Bro. S.G. Norris say that.
The second is:
The Jewish Talmud says Moses gave Israel 613 commandments, David reduced them to 10, Isaiah to 2, and Habakkuk to one, "The just shall live by his faith."
