Passage
For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
Romans 1:15 So, as much as in me is, I am ready to preach the gospel to you that are at Rome also.
Romans 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
Romans 1:17 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
Romans 1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;
Romans 1:19 Because that which may be known of God is manifest in them; for God hath shewed it unto them.
The verse centers on "faith", "therein", "righteousness", "revealed", "written", "just", and "shall". It is saying that the verse draws attention to "faith" and "therein", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "For I am not ashamed of the..." into verse 18's "For the wrath of God is revealed...", so "faith" and "therein" belong inside that flow. In Romans context, the local focus is righteousness by faith, union with Christ, life in the Spirit, and God's covenant faithfulness.
A plain takeaway is to answer the verse's own emphasis on "faith" and "therein" with trust shaped by these words, not by a vague optimism outside the passage.
