Passage
Cast all your care on him: for he careth for you.
Cast all your care on him: for he careth for you.
1 Peter 5:5 Likewise ye yonger, submit your selues vnto the elders, and submit your selues euery man, one to another: decke your selues inwardly in lowlinesse of minde: for God resisteth the proude, and giueth grace to the humble.
1 Peter 5:6 Humble your selues therefore vnder the mightie hand of God, that he may exalt you in due time.
1 Peter 5:7 Cast all your care on him: for he careth for you.
1 Peter 5:8 Be sober, and watch: for your aduersarie the deuil as a roaring lyon walketh about, seeking whom he may deuoure:
1 Peter 5:9 Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren which are in the world.
The verse centers on "cast", "care", and "careth". It is saying that the verse draws attention to "cast" and "care", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "Humble your selues therefore vnder the mightie..." into verse 8's "Be sober and watch for your aduersarie...", so "cast" and "care" belong inside that flow. In 1 Peter context, the local focus is hope in suffering, holy conduct, submission, and grace.
A plain takeaway is to answer the verse's own emphasis on "cast" and "care" with trust shaped by these words, not by a vague optimism outside the passage.
