For I am persuaded that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which [is] in Christ Jesus our Lord.
Romans 8:36 According as it is written, For thy sake we are put to death all the day long; we have been reckoned as sheep for slaughter.
Romans 8:37 But in all these things we more than conquer through him that has loved us.
Romans 8:38 For I am persuaded that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers,
Romans 8:39 nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which [is] in Christ Jesus our Lord.
The verse centers on "persuaded", "neither", "death", "life", "angels", "principalities", "things", and "present". It is saying that the verse draws attention to "persuaded" and "neither", so its meaning should be read from those terms before moving to application.
The prior verse says "But in all these things we more...", giving immediate footing for "persuaded" and "neither". 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 "persuaded" and "neither" with trust shaped by these words, not by a vague optimism outside the passage.
