Passage
righteousness of God by faith of Jesus Christ towards all, and upon all those who believe: for there is no difference;
righteousness of God by faith of Jesus Christ towards all, and upon all those who believe: for there is no difference;
Romans 3:20 Wherefore by works of law no flesh shall be justified before him; for by law [is] knowledge of sin.
Romans 3:21 But now without law righteousness of God is manifested, borne witness to by the law and the prophets;
Romans 3:22 righteousness of God by faith of Jesus Christ towards all, and upon all those who believe: for there is no difference;
Romans 3:23 for all have sinned, and come short of the glory of God;
Romans 3:24 being justified freely by his grace through the redemption which [is] in Christ Jesus;
The verse centers on "faith", "righteousness", "jesus", "christ", "towards", "upon", "believe", and "difference". It is saying that the verse draws attention to "faith" and "righteousness", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 21's "But now without law righteousness of God..." into verse 23's "for all have sinned and come short...", so "faith" and "righteousness" 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 "righteousness" with trust shaped by these words, not by a vague optimism outside the passage.
