In the past, many Biblical scholars found "from faith to faith" to be difficult to understand. I recall the scholarly books that found it puzzling and enigmatic.
1.17 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;
19 Because that which may be known of God is manifest in them; for God hath shewed it unto them.
When people began to emphasize the Faith of Jesus, the scales dropped from their eyes. Jesus has all the attributes of a believer because He was one from the beginning and remains the ultimate Believer.
For therein is the righteousness of God revealed
from faith to faith: as it is written, The just shall live by faith.
Once the Faith of Jesus is appreciated as a rare book or article, the readers open their eyes to the meaning of Romans 1:17.
