Our remaining peaceful in hard times completely disarms the devil. He does not know what to do with someone who refuses to get upset. Peace is Power! When we remain calm, God moves to help us. Keeping our peace shows we trust God. In the scriptures, God told the Israelites the battle was not theirs but His, and I believe that promise is also for us today. Let God fight your battles while you remain at rest, trusting Him.
In the beginning the Word already existed. The Word was with God, and the Word was God.  He existed in the beginning with God.  God created everything through him, and nothing was created except through him.  The Word gave life to everything that was created, and his life brought light to everyone.  The light shines in the darkness, and the darkness can never extinguish it.
- John 1:1-5
As Pharaoh approached, the Israelites looked up, and there were the Egyptians, marching after them. They were terrified and cried out to the Lord.  They said to Moses, “Was it because there were no graves in Egypt that you brought us to the desert to die? What have you done to us by bringing us out of Egypt?  Didn’t we say to you in Egypt, ‘Leave us alone; let us serve the Egyptians’? It would have been better for us to serve the Egyptians than to die in the desert!”  Moses answered the people, “Do not be afraid. Stand firm and you will see the deliverance the Lord will bring you today. The Egyptians you see today you will never see again.  The Lord will fight for you; you need only to be still.” - Exodus 14:10-14
