Again, I am always surprised when I am directed in different ways toward a similar theme or topic. I've spent a lot of time in the car lately, and Sunday had the opportunity to listen to part of a sermon on Philippians 4. The chapter fits perfectly along the lines of Isaiah 26 and finding peace.
Rejoice. Be gentle. Don't worry. Give thanks. Pray. "And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus." I'd say that's a formula worth trying.
On a side note, I just read an opinion peace in the New York Times on Sandra Bullock's situation and whether or not the Oscar was a good trade for a broken relationship. The author of the piece, David Brooks, says no. The focus of the column really isn't the actress, but research on how personal relationships bring more happiness than career successes and material wealth. It's research worth pondering in a gimme, gimme culture.
