Passage
Casting all your care upon him; for he careth for you.
Casting all your care upon him; for he careth for you.
1 Peter 5:5 Likewise, ye younger, submit yourselves unto the elder. Yea, all of you be subject one to another, and be clothed with humility: for God resisteth the proud, and giveth grace to the humble.
1 Peter 5:6 Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time:
1 Peter 5:7 Casting all your care upon him; for he careth for you.
1 Peter 5:8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:
1 Peter 5:9 Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.
The verse centers on "casting", "care", "upon", and "careth". It is saying that the verse draws attention to "casting" and "care", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "Humble yourselves therefore under the mighty hand..." into verse 8's "Be sober be vigilant because your adversary...", so "casting" 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 "casting" and "care" with trust shaped by these words, not by a vague optimism outside the passage.
