Peace is not always the absence of trouble but rest even in the midst of trouble. And  one of the characteristics of a believer is ability to be at peace all the time.

one of the ways we know a man of faith is the ability to be peaceful even amidst all odds,they are not easily moved by circumstances around them. And this is an allocation in which our Lord Jesus Christ promised us ,Christians must come to that estate where the peace of God will keep our hearts and minds.

I believe this is a  message  for someone ,do not fret about anything but in everything by prayer and thanksgiving make your requests known un to God.
