Everyone suffers anxiety of some kind at some point. Paul says we need to bring everything to God in prayer. We come to Him with thanksgiving, not for the situation, but for our salvation, acknowledging that we don’t deserve it. When we bring our prayers and petitions, God gives us His peace. Paul was in prison when he wrote this, not knowing if he was going to be executed. This peace might not change our situation but enables us to cope. We can’t understand this peace because we can’t understand God, but our understanding of Him will increase through trusting Him more. We don’t just need Him at the points of anxiety but every moment. This protection will only happen if we are in Christ Jesus.
