Isaiah 26:3
You will guard him and keep him in perfect and constant peace whose mind is stayed on You, because he commits himself to You, leans on You, and hopes confidently in You.

When our thoughts and our hope and confidence is in Him, we can have peace in every situation. We don't have to be shaken in bad times. We know the One who holds the world in His hand. So trust Him, He will not let you down. He has not forgotten you. Allow yourself to be saturated in His perfect peace.
