When you have peace with God, it doesn’t matter if the rest of the world is at war with you.
On the other hand, if you don’t have peace with God, it won’t matter if the rest of the world loves you.
Jesus came to be our peace with God. He died so that you could inherit that peace. He Himself is the guarantee – the proof – that the peace is yours.
Since you have that peace with God, don’t let anyone disturb it. Don’t even allow yourself to disturb it. Ask Him now how He wants you to live today. He will guide you. And you can be peaceful all day long.
