God desires for you to live in peace and rest no matter what is happening around you. When you believe God, you enter into His perfect rest. But if you are controlled by your circumstances, if you’re up when things are up and down when things don’t go your way, then life is going to be a roller coaster. God’s plan is for you to be stable, consistent, not moved by any of these things.
Anytime you face adversity or hit a tough time, one of the best things you can do is simply stay calm and keep your peace. When you’re in peace, that’s a position of power. You’re saying with your actions, “God, I trust You. I know You are still on the throne. This may be difficult, but I know You are fighting my battles.” That’s what faith is—believing that God is who He says He is and that He is a rewarder of those who seek Him. When you believe God, you enter into rest and walk in peace and joy no matter what is happening around you.
