For many people, worry fills a void that comes from not being in control. There is an innate awareness that we are not sovereign and that someone else is ultimately calling the shots. Even an atheist has to yield his life to fate, or karma, or luck. The obedient Christian will take Paul’s command in Philippians 4:6 at face value and drop the habit of worry. The basis for such a change is that we replace it with faith in God. But it’s not that easy. We were created by God to think, and the more we think about what is going on around us, the more we are tempted to worry. But that is no longer an option if we are to remain obedient. Removing worry creates a vacuum. This has the potential to drive us to a thousand feeble substitutes to fill the void, unintentionally modeling the unbelievers strategy (Matthew 6:31-32). The only real solution is prayer. Through that act alone the human mind is insulated from fear to the degree we replace worry with trust in the form of active prayer. With practice and divine assistance, the new habit of prayer can be an instinctive reaction to calamity.
