Have peace in everything. A. Not another admonition, but the result of following the above. B. Peace of God. Since the peace stands in contrast to the anxiety in verse 6, inner contentment is probably in view. C. Beyond our understanding.
Christians ought to be as worried and stressed-out as anyone.
Instead, God can give us a sense of peace in the midst of turmoil. A life insurance company did a study. They learned that people who attend church once a week, live on the average, 5.7 years longer than the general public. The contentment and joy of knowing God is truly health-giving. We can't explain it, but deep down we know it is true.
