This is important to understand so you know what to do when trouble comes.
Your innermost being is always at peace, because it is the very residence of the Holy Spirit. So, when trouble comes, all you need to do is quiet your mind and tune in to your spirit.
Don't wait for trouble to leave or fade away. You don't have to endure a certain amount of trouble before you find peace.
Peace is always available. It's already in you. You just have to choose to let your spirit lead instead of your mind.
