Audio commentary on this verse

Note 3 at Rom. 1:17: The expression "from faith to faith" describes the means whereby righteousness is given and retained. God's righteousness cannot be earned. It can only be acquired through faith. As proof that righteousness received by faith is not a new idea or concept, Paul quotes Habakkuk 2:4, "The just shall live by faith" (also quoted in Gal. 3:11 and Heb. 10:38).

Note 4 at Rom. 1:17: The just shall live by faith. They don't just visit faith every once and awhile, or vacation there once a year, they live in and by faith.
