From the sermon Think on these things, Philippians 4:8-9

The peace of God is connected to our obedience to God. More than any previous generation in the history of the world, we have more trinkets, entertainment, and devices that vie for our attention. It seems that as the things that seek our attention have grown, so has the amount of our anxiety and worry. We live in a culture that is consumed with anxiety. The peace of God is known when you turn your attention away from the things of this world and turn to the Lord.
