Isaiah26:3

You will keep him in perfect peace, whose mind is stayed on You, because he trusts You.  Trust in the Lord forever, for Yah, the Lord, is everlasting strength.  

We can have peace in a troubled world.  It takes a little practice and patience as we learn the word and how God operates.  The benefits from trusting in God far exceed anything the world can offer us.  God offers us wisdom, prosperity, peace, and strength, and that is a shortlist.  Our peace relies on choices and choosing the word first in our life.
