Peace Beyond Our Understanding
What is your definition of peace? Peace is more than quiet. The peace of God is bigger than we can understand. Why is this? Because God is bigger and wiser than we can understand. The peace of God speaks to your hearts and minds in the present and it will continue to speak even in the most difficult days in your future. You do not know what they will be, but God always does.
So if you struggle with no peace the answer to your problem is in the previous verse. There Paul bids everyone who is anxious to go to God with prayer and petitions with thanksgiving and so talk to God in prayer. Prayer has a way of giving everything you struggle with to God and helps us realize that he is always there to hear and to help.
