Setting the terms: fear, care, and anxious thought
The English word “anxiety” gathers several biblical ideas: fear in the face of threat, “care” that weighs the heart, and restless concern about tomorrow. Scripture does not treat these as imaginary. It gives language for them and then directs the sufferer toward God.
In the Gospels, Jesus names the condition plainly. He tells Martha she is “worried and upset about many things” (Luke 10:41), and he warns that hearts can be “weighed down with… the anxieties of life” (Luke 21:34). The Psalms repeatedly place fear before God rather than denying it: “When I am afraid, I put my trust in you” (Psalm 56:3).
Matthew Henry’s Commentary · Matthew Henry
On Philippians 4, Henry stresses that the cure for carefulness is not stoic indifference but prayer with thanksgiving, committing every concern to God who cares for his people.
Apostolic counsel: cast cares and pray
Peter addresses scattered believers under pressure: “Cast all your anxiety on him because he cares for you” (1 Peter 5:7). The verb evokes throwing a burden onto another; the ground is God’s paternal care, not the strength of the sufferer’s resolve.
Paul’s parallel instruction in Philippians 4:6–7 is more detailed. Believers are told not to be anxious about anything, but in everything, by prayer and petition with thanksgiving, to present requests to God. The promised result is the peace of God that “will guard your hearts and your minds in Christ Jesus.” Anxiety is met not by emptying the mind, but by filling prayer with specific requests and gratitude.
Jamieson-Fausset-Brown Bible Commentary · JFB
JFB on 1 Peter 5:7 links the casting of care to humility in the prior verse: pride keeps the burden; humility hands it to God. On Philippians 4:6 they note thanksgiving as the companion of petition, lest prayer itself become another form of anxious grasping.
Jesus on provision: Matthew 6:25–34
In the Sermon on the Mount, Jesus forbids anxious concern about food, drink, and clothing (Matthew 6:25–34). He argues from lesser to greater: if the Father feeds birds and clothes lilies, how much more will he care for his children? The climax is not “feel nothing,” but “seek first his kingdom and his righteousness,” with the assurance that “all these things will be given to you as well,” and the practical word: “do not worry about tomorrow.”
Proverbs adds a pastoral observation from wisdom literature: “Anxiety weighs down the heart, but a kind word cheers it up” (Proverbs 12:25). The biblical witness holds together divine care, communal kindness, and disciplined trust.
John Gill’s Exposition of the Bible · John Gill
Gill on Matthew 6 emphasizes that Christ’s prohibition targets distrustful solicitude about worldly necessaries, not diligent labor or lawful planning. The Father’s knowledge of our needs is the theological ground of the command.
