Be careful for nothing

In the King James English of 1611, 'careful' meant full of care, anxious, worried; it did not mean cautious or attentive, as it does today. Paul is not telling believers to be careless or unconcerned about their responsibilities. He is forbidding the corrosive inner state of being pulled apart by worry.

The Greek verb, merimnao, pictures a mind divided, torn between competing concerns, unable to settle. Jesus uses the identical verb in the Sermon on the Mount when He tells His hearers not to be anxious about food, drink, or clothing, because their heavenly Father already knows what they need (Matthew 6:31-32).

Paul does not simply say stop being anxious and leave it there. The rest of the verse gives the mechanism: 'but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.' Anxiety is not repressed; it is handed over.

This matters pastorally. A command to stop feeling anxious, with no outlet given, tends to produce guilt on top of the original worry. Paul instead gives a place for the care to go: into prayer, joined with thanksgiving, addressed directly to God.

The instruction's authority comes partly from where it was written. Paul is a prisoner facing an uncertain trial, potentially a death sentence, when he tells the Philippians not to be consumed by anxious care. This is not advice from someone insulated from real threat.

Read this way, the command becomes far more demanding and far more credible. Paul is not minimizing the church's worries from a position of safety; he is inviting them into the same discipline he is practicing himself, in chains.
