In these verses Paul reminds the Philippians to “be anxious for nothing” because “the peace of God will guard your hearts and minds in Christ Jesus”. How can we appropriate God’s peace in our lives? “By prayer and supplication with thanksgiving, letting our requests be made known to God”. Scripture is full of examples of people calling out to God in prayer (psalm 39:12, 54:2) and of God responding to prayer (Is 38:4-6) and promising to respond (James 5:16). Anticipatory prayer or prayer as “supplication with thanksgiving” is being so confident in God’s responsiveness to our prayer that we thank him for that answer ahead of time. A great example of this is in John 11 when Jesus asks the father to raise Lazarus from the dead and says “I thank you that you have heard me” even before Lazarus comes out. 1 Peter 5:7 then offers the source for peace through prayer. As we have a God who hears and responds, we can trust this happens in the context of his care for us (as 1Peter 5:7)…”casting all your anxiety on Him because He cares for you”.
