The world is increasingly complicated and chaotic. Peace is rare and difficult to find in the world around us, but it is available to you.
Peace comes when we hand over the chaos in our world to Jesus. This is why Jesus said not to worry and explained, "But seek first his kingdom and his righteousness, and all these things will be given to you as well." -Matthew 6:33
I've seen people do all kinds of things to battle chaos in their worlds. People try to create a peaceful atmosphere, practice clearing their minds, participate in extreme exercise, and even undergo surgical procedures to reduce stress. These tactics do not resolve the source of chaos. They just treat the symptoms.
A simple and effective way to cut the chaos out of your life is to just surrender this stress to Jesus each day and let his peace reign in your life.
