Passage
And the way of peace have they not known:
And the way of peace have they not known:
Romans 3:15 Their feet are swift to shed blood:
Romans 3:16 Destruction and misery are in their ways:
Romans 3:17 And the way of peace have they not known:
Romans 3:18 There is no fear of God before their eyes.
Romans 3:19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
The verse centers on "peace" and "known". It is saying that the verse draws attention to "peace" and "known", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "Destruction and misery are in their ways..." into verse 18's "There is no fear of God before...", so "peace" and "known" 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 "peace" and "known" with trust shaped by these words, not by a vague optimism outside the passage.
