Passage
who is marked out Son of God in power, according to the Spirit of sanctification, by the rising again from the dead,) Jesus Christ our Lord;
who is marked out Son of God in power, according to the Spirit of sanctification, by the rising again from the dead,) Jesus Christ our Lord;
Romans 1:2 which He announced before through His prophets in holy writings--
Romans 1:3 concerning His Son, (who is come of the seed of David according to the flesh,
Romans 1:4 who is marked out Son of God in power, according to the Spirit of sanctification, by the rising again from the dead,) Jesus Christ our Lord;
Romans 1:5 through whom we did receive grace and apostleship, for obedience of faith among all the nations, in behalf of his name;
Romans 1:6 among whom are also ye, the called of Jesus Christ;
The verse centers on "Spirit", "marked", "power", "sanctification", "rising", "again", "dead", and "jesus". It is saying that the verse draws attention to "Spirit" and "marked", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "concerning His Son who is come of..." into verse 5's "through whom we did receive grace and...", so "Spirit" and "marked" 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 "Spirit" and "marked" with trust shaped by these words, not by a vague optimism outside the passage.
