By faith Noah, having been divinely warned concerning the things not yet seen, having feared, did prepare an ark to the salvation of his house, through which he did condemn the world, and of the righteousness according to faith he became heir.
Hebrews 11:5 By faith Enoch was translated--not to see death, and was not found, because God did translate him; for before his translation he had been testified to--that he had pleased God well,
Hebrews 11:6 and apart from faith it is impossible to please well, for it behoveth him who is coming to God to believe that He is, and to those seeking Him He becometh a rewarder.
Hebrews 11:7 By faith Noah, having been divinely warned concerning the things not yet seen, having feared, did prepare an ark to the salvation of his house, through which he did condemn the world, and of the righteousness according to faith he became heir.
Hebrews 11:8 By faith Abraham, being called, did obey, to go forth to the place that he was about to receive for an inheritance, and he went forth, not knowing whither he doth go;
Hebrews 11:9 by faith he did sojourn in the land of the promise as a strange country, in tabernacles having dwelt with Isaac and Jacob, fellow-heirs of the same promise,
The verse centers on "world", "condemn", "faith", "noah", "having", "been", "divinely", and "warned". It is saying that the verse draws attention to "world" and "condemn", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "and apart from faith it is impossible..." into verse 8's "By faith Abraham being called did obey...", so "world" and "condemn" belong inside that flow. In Hebrews context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "world" and "condemn" with trust shaped by these words, not by a vague optimism outside the passage.
