Passage
Because that which is known of God is manifest in them. For God hath manifested it unto them.
Because that which is known of God is manifest in them. For God hath manifested it unto them.
Romans 1:17 For the justice of God is revealed therein, from faith unto faith, as it is written: The just man liveth by faith.
Romans 1:18 For the wrath of God is revealed from heaven against all ungodliness and injustice of those men that detain the truth of God in injustice:
Romans 1:19 Because that which is known of God is manifest in them. For God hath manifested it unto them.
Romans 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made. His eternal power also and divinity: so that they are inexcusable.
Romans 1:21 Because that, when they knew God, they have not glorified him as God or given thanks: but became vain in their thoughts. And their foolish heart was darkened.
The verse centers on "known", "manifest", "hath", and "manifested". It is saying that the verse draws attention to "known" and "manifest", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "For the wrath of God is revealed..." into verse 20's "For the invisible things of him from...", so "known" and "manifest" 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 "known" and "manifest" with trust shaped by these words, not by a vague optimism outside the passage.
