In Philippians 4:6–7, Paul sums up an entire theology of prayer practice in very concise form: “Pray with gratitude, and the peace of Christ, which is bigger than knowledge or understanding, will guard both your mind and your heart in Christ Jesus.” Only a pre-existent attitude of gratitude, a deliberate choice of love over fear, a desire to be positive instead of negative, will allow us to live in the spacious place Paul describes as “the peace of Christ.” - Richard Rohr
